ABOUT THE SPEAKER
Jared Diamond - Civilization scholar
Jared Diamond investigates why cultures prosper or decline -- and what we can learn by taking a broad look across many kinds of societies.

Why you should listen

In his books Guns, Germs and Steel and Collapse (and the popular PBS and National Geographic documentaries they inspired), big-picture scholar Jared Diamond explores civilizations and why they all seem to fall. Now in his latest book, The World Until Yesterday, Diamond examines small, traditional, tribal societies -- and suggests that modern civilization is only our latest solution to survival.
 
Diamond’s background in evolutionary biology, geography and physiology informs his integrated vision of human history. He posits that success -- and failure -- depends on how well societies adapt to their changing environment.

Jared Diamond: How societies can grow old better

Filmed:
1,100,581 views

There's an irony behind the latest efforts to extend human life: It's no picnic to be an old person in a youth-oriented society. Older people can become isolated, lacking meaningful work and low on funds. In this intriguing talk, Jared Diamond looks at how many different societies treat their elders -- some better, some worse -- and suggests we all take advantage of experience.

To give me an idea of how many of you here
0
745
2229
00:14
may find what I'm about to tell you
1
2974
2122
00:17
of practical value,
2
5096
1625
00:18
let me ask you please to raise your hands:
3
6721
2689
00:21
Who here is either over 65 years old
4
9410
3567
00:24
or hopes to live past age 65
5
12977
3769
00:28
or has parents or grandparents who did live
6
16746
2945
00:31
or have lived past 65,
7
19691
1967
00:33
raise your hands please. (Laughter)
8
21658
2585
00:36
Okay. You are the people to whom my talk
9
24243
2154
00:38
will be of practical value. (Laughter)
10
26397
2434
00:40
The rest of you
11
28831
1657
00:42
won't find my talk personally relevant,
12
30488
1788
00:44
but I think that you will still find the subject
13
32276
1914
00:46
fascinating.
14
34190
1647
00:47
I'm going to talk about growing older
15
35837
1632
00:49
in traditional societies.
16
37469
2419
00:51
This subject constitutes just one chapter
17
39888
2746
00:54
of my latest book, which compares
18
42634
2591
00:57
traditional, small, tribal societies
19
45225
3217
01:00
with our large, modern societies,
20
48442
2550
01:02
with respect to many topics
21
50992
1625
01:04
such as bringing up children,
22
52617
1859
01:06
growing older, health, dealing with danger,
23
54476
3921
01:10
settling disputes, religion
24
58397
2345
01:12
and speaking more than one language.
25
60742
2791
01:15
Those tribal societies, which constituted
26
63533
2557
01:18
all human societies for most of human history,
27
66090
2985
01:21
are far more diverse than are our modern,
28
69075
3294
01:24
recent, big societies.
29
72369
2167
01:26
All big societies that have governments,
30
74536
2363
01:28
and where most people are strangers to each other,
31
76899
2266
01:31
are inevitably similar to each other
32
79165
2348
01:33
and different from tribal societies.
33
81513
2848
01:36
Tribes constitute thousands of natural experiments
34
84361
3311
01:39
in how to run a human society.
35
87672
2549
01:42
They constitute experiments from which we ourselves
36
90221
2807
01:45
may be able to learn.
37
93028
2402
01:47
Tribal societies shouldn't be scorned
38
95430
2020
01:49
as primitive and miserable,
39
97450
1736
01:51
but also they shouldn't be romanticized
40
99186
2371
01:53
as happy and peaceful.
41
101557
2217
01:55
When we learn of tribal practices,
42
103774
2259
01:58
some of them will horrify us,
43
106033
1774
01:59
but there are other tribal practices which,
44
107807
2550
02:02
when we hear about them,
45
110357
1349
02:03
we may admire and envy
46
111706
1947
02:05
and wonder whether we could adopt those practices
47
113653
2224
02:07
ourselves.
48
115877
2697
02:10
Most old people in the U.S. end up living
49
118574
3087
02:13
separately from their children
50
121661
1987
02:15
and from most of their friends
51
123648
1506
02:17
of their earlier years,
52
125154
1692
02:18
and often they live in separate
retirements homes for the elderly,
53
126846
3854
02:22
whereas in traditional societies,
54
130700
2208
02:24
older people instead live out their lives
55
132908
2834
02:27
among their children, their other relatives,
56
135742
2166
02:29
and their lifelong friends.
57
137908
2397
02:32
Nevertheless, the treatment of the elderly
58
140305
2169
02:34
varies enormously among traditional societies,
59
142474
3165
02:37
from much worse to much better
60
145639
2181
02:39
than in our modern societies.
61
147820
2958
02:42
At the worst extreme, many traditional societies
62
150778
2797
02:45
get rid of their elderly
63
153575
1813
02:47
in one of four increasingly direct ways:
64
155388
3531
02:50
by neglecting their elderly
65
158919
1663
02:52
and not feeding or cleaning them until they die,
66
160582
3429
02:56
or by abandoning them when the group moves,
67
164011
3054
02:59
or by encouraging older people to commit suicide,
68
167065
3139
03:02
or by killing older people.
69
170204
3045
03:05
In which tribal societies do children
70
173249
2749
03:07
abandon or kill their parents?
71
175998
2386
03:10
It happens mainly under two conditions.
72
178384
3024
03:13
One is in nomadic, hunter-gather societies
73
181408
2980
03:16
that often shift camp
74
184388
1723
03:18
and that are physically incapable
75
186111
2179
03:20
of transporting old people who can't walk
76
188290
3123
03:23
when the able-bodied younger people already
77
191413
2560
03:25
have to carry their young children
78
193973
1935
03:27
and all their physical possessions.
79
195908
2818
03:30
The other condition is in societies
80
198726
2164
03:32
living in marginal or fluctuating environments,
81
200890
3310
03:36
such as the Arctic or deserts,
82
204200
2333
03:38
where there are periodic food shortages,
83
206533
2584
03:41
and occasionally there just isn't enough food
84
209117
1929
03:43
to keep everyone alive.
85
211046
2480
03:45
Whatever food is available has to be reserved
86
213526
2424
03:47
for able-bodied adults and for children.
87
215950
4325
03:52
To us Americans, it sounds horrible
88
220275
2900
03:55
to think of abandoning or killing
89
223175
2233
03:57
your own sick wife or husband
90
225408
2181
03:59
or elderly mother or father,
91
227589
2299
04:01
but what could those traditional societies
92
229888
3759
04:05
do differently?
93
233647
1483
04:07
They face a cruel situation of no choice.
94
235130
3820
04:10
Their old people had to do it to their own parents,
95
238950
2995
04:13
and the old people know
96
241945
1288
04:15
what now is going to happen to them.
97
243233
3151
04:18
At the opposite extreme
98
246384
1814
04:20
in treatment of the elderly, the happy extreme,
99
248198
2679
04:22
are the New Guinea farming societies
100
250877
1987
04:24
where I've been doing my fieldwork
for the past 50 years,
101
252864
2997
04:27
and most other sedentary traditional societies
102
255861
3247
04:31
around the world.
103
259108
2086
04:33
In those societies, older people are cared for.
104
261194
2948
04:36
They are fed. They remain valuable.
105
264142
2350
04:38
And they continue to live in the same hut
106
266492
2188
04:40
or else in a nearby hut near their children,
107
268680
2687
04:43
relatives and lifelong friends.
108
271367
3899
04:47
There are two main sets of reasons for this variation
109
275266
2432
04:49
among societies in their treatment
110
277698
2355
04:52
of old people.
111
280053
1397
04:53
The variation depends especially
112
281450
1637
04:55
on the usefulness of old people
113
283087
2270
04:57
and on the society's values.
114
285357
2713
05:00
First, as regards usefulness,
115
288070
2323
05:02
older people continue to perform useful services.
116
290393
3455
05:05
One use of older people in traditional societies
117
293848
2685
05:08
is that they often are still effective
118
296533
2000
05:10
at producing food.
119
298533
2413
05:12
Another traditional usefulness of older people
120
300946
2413
05:15
is that they are capable of babysitting
121
303359
3279
05:18
their grandchildren,
122
306638
1694
05:20
thereby freeing up their own adult children,
123
308332
2670
05:23
the parents of those grandchildren,
124
311002
1871
05:24
to go hunting and gathering
food for the grandchildren.
125
312873
3473
05:28
Still another traditional value of older people
126
316346
2205
05:30
is in making tools, weapons, baskets,
127
318551
2920
05:33
pots and textiles.
128
321471
1957
05:35
In fact, they're usually the people who are best at it.
129
323428
3249
05:38
Older people usually are the leaders
130
326677
2768
05:41
of traditional societies,
131
329445
1849
05:43
and the people most knowledgeable about politics,
132
331294
3259
05:46
medicine, religion, songs and dances.
133
334553
3999
05:50
Finally, older people in traditional societies
134
338552
2452
05:53
have a huge significance that would never occur
135
341004
3927
05:56
to us in our modern, literate societies,
136
344931
3676
06:00
where our sources of information are books
137
348607
2415
06:03
and the Internet.
138
351022
1684
06:04
In contrast, in traditional societies without writing,
139
352706
3423
06:08
older people are the repositories of information.
140
356129
3686
06:11
It's their knowledge that spells the difference
141
359815
2565
06:14
between survival and death for their whole society
142
362380
3750
06:18
in a time of crisis caused by rare events
143
366130
3258
06:21
for which only the oldest people alive
144
369388
2595
06:23
have had experience.
145
371983
2289
06:26
Those, then, are the ways in which older people
146
374272
2470
06:28
are useful in traditional societies.
147
376742
2903
06:31
Their usefulness varies and contributes
148
379645
2562
06:34
to variation in the society's treatment
149
382207
2618
06:36
of the elderly.
150
384825
2000
06:38
The other set of reasons for variation
151
386825
1819
06:40
in the treatment of the elderly is
152
388644
1875
06:42
the society's cultural values.
153
390519
3235
06:45
For example, there's particular emphasis
154
393754
2026
06:47
on respect for the elderly in East Asia,
155
395780
3209
06:50
associated with Confucius' doctrine
156
398989
2911
06:53
of filial piety, which means obedience,
157
401900
3550
06:57
respect and support for elderly parents.
158
405450
4094
07:01
Cultural values that emphasize
respect for older people
159
409544
3713
07:05
contrast with the low status of the elderly
160
413257
2817
07:08
in the U.S.
161
416074
2162
07:10
Older Americans are at a big disadvantage
162
418236
2558
07:12
in job applications.
163
420794
2113
07:14
They're at a big disadvantage in hospitals.
164
422907
2535
07:17
Our hospitals have an explicit policy
165
425442
2623
07:20
called age-based allocation of healthcare resources.
166
428065
4967
07:25
That sinister expression means that
167
433032
2773
07:27
if hospital resources are limited,
168
435805
2206
07:30
for example if only one donor heart
169
438011
2050
07:32
becomes available for transplant,
170
440061
2298
07:34
or if a surgeon has time to operate
171
442359
2102
07:36
on only a certain number of patients,
172
444461
2511
07:38
American hospitals have an explicit policy
173
446972
2950
07:41
of giving preference to younger patients
174
449922
2320
07:44
over older patients
175
452242
1480
07:45
on the grounds that younger patients are considered
176
453722
3244
07:48
more valuable to society
177
456966
1817
07:50
because they have more years of life ahead of them,
178
458783
2645
07:53
even though the younger patients have fewer years
179
461428
2660
07:56
of valuable life experience behind them.
180
464088
3982
08:00
There are several reasons for this low status
181
468070
2228
08:02
of the elderly in the U.S.
182
470298
2342
08:04
One is our Protestant work ethic
183
472640
3185
08:07
which places high value on work,
184
475825
2313
08:10
so older people who are no longer working
185
478138
2223
08:12
aren't respected.
186
480361
1983
08:14
Another reason is our American emphasis
187
482344
2857
08:17
on the virtues of self-reliance and independence,
188
485201
3383
08:20
so we instinctively look down on older people
189
488584
3069
08:23
who are no longer self-reliant and independent.
190
491653
3597
08:27
Still a third reason is our American cult of youth,
191
495250
4101
08:31
which shows up even in our advertisements.
192
499351
2808
08:34
Ads for Coca-Cola and beer always depict
193
502159
3264
08:37
smiling young people,
194
505423
1555
08:38
even though old as well as young people
195
506978
1970
08:40
buy and drink Coca-Cola and beer.
196
508948
2322
08:43
Just think, what's the last time you saw
197
511270
2003
08:45
a Coke or beer ad depicting smiling people
198
513273
2677
08:47
85 years old? Never.
199
515950
2949
08:50
Instead, the only American ads
200
518899
1806
08:52
featuring white-haired old people
201
520705
2006
08:54
are ads for retirement homes and pension planning.
202
522711
3865
08:58
Well, what has changed in the status
203
526576
2050
09:00
of the elderly today
204
528626
1983
09:02
compared to their status in traditional societies?
205
530609
3389
09:05
There have been a few changes for the better
206
533998
1870
09:07
and more changes for the worse.
207
535868
2205
09:10
Big changes for the better
208
538073
1601
09:11
include the fact that today we enjoy
209
539674
2151
09:13
much longer lives,
210
541825
1984
09:15
much better health in our old age,
211
543809
2294
09:18
and much better recreational opportunities.
212
546103
3638
09:21
Another change for the better is that we now have
213
549741
2270
09:24
specialized retirement facilities
214
552011
2840
09:26
and programs to take care of old people.
215
554851
3351
09:30
Changes for the worse begin with the cruel reality
216
558202
2868
09:33
that we now have
217
561070
1689
09:34
more old people and fewer young people
218
562759
2574
09:37
than at any time in the past.
219
565333
2684
09:40
That means that all those old people
220
568017
1751
09:41
are more of a burden on the few young people,
221
569768
2425
09:44
and that each old person has less individual value.
222
572193
4486
09:48
Another big change for the worse
in the status of the elderly
223
576679
3184
09:51
is the breaking of social ties with age,
224
579863
2677
09:54
because older people, their children,
225
582540
1844
09:56
and their friends,
226
584384
1316
09:57
all move and scatter independently of each other
227
585700
2850
10:00
many times during their lives.
228
588550
2254
10:02
We Americans move on the average
229
590804
1813
10:04
every five years.
230
592617
1953
10:06
Hence our older people are likely
231
594570
2031
10:08
to end up living distant from their children
232
596601
2307
10:10
and the friends of their youth.
233
598908
2803
10:13
Yet another change for the worse
in the status of the elderly
234
601711
3162
10:16
is formal retirement from the workforce,
235
604873
3730
10:20
carrying with it a loss of work friendships
236
608603
2750
10:23
and a loss of the self-esteem associated with work.
237
611353
4140
10:27
Perhaps the biggest change for the worse
238
615493
2485
10:29
is that our elderly are objectively
239
617978
2873
10:32
less useful than in traditional societies.
240
620851
3162
10:36
Widespread literacy means that they are no longer
241
624013
2963
10:38
useful as repositories of knowledge.
242
626976
2631
10:41
When we want some information,
243
629607
1943
10:43
we look it up in a book or we Google it
244
631550
2261
10:45
instead of finding some old person to ask.
245
633811
3470
10:49
The slow pace of technological change
246
637281
2087
10:51
in traditional societies
247
639368
1822
10:53
means that what someone learns there as a child
248
641190
2850
10:56
is still useful when that person is old,
249
644040
2659
10:58
but the rapid pace of technological change today
250
646699
3603
11:02
means that what we learn as children
251
650302
2067
11:04
is no longer useful 60 years later.
252
652369
2890
11:07
And conversely, we older people are not fluent
253
655259
2379
11:09
in the technologies essential for surviving
254
657638
3034
11:12
in modern society.
255
660672
1971
11:14
For example, as a 15-year-old,
256
662643
2173
11:16
I was considered outstandingly
good at multiplying numbers
257
664816
3590
11:20
because I had memorized the multiplication tables
258
668406
3195
11:23
and I know how to use logarithms
259
671601
2145
11:25
and I'm quick at manipulating a slide rule.
260
673746
2863
11:28
Today, though, those skills are utterly useless
261
676609
3086
11:31
because any idiot
262
679695
2371
11:34
can now multiply eight-digit numbers
263
682066
2358
11:36
accurately and instantly with a pocket calculator.
264
684424
3187
11:39
Conversely, I at age 75
265
687611
2170
11:41
am incompetent at skills
266
689781
2664
11:44
essential for everyday life.
267
692445
2454
11:46
My family's first TV set in 1948
268
694899
2784
11:49
had only three knobs that I quickly mastered:
269
697683
3053
11:52
an on-off switch, a volume knob,
270
700736
2750
11:55
and a channel selector knob.
271
703486
2221
11:57
Today, just to watch a program
272
705707
2088
11:59
on the TV set in my own house,
273
707795
2456
12:02
I have to operate a 41-button TV remote
274
710251
3717
12:05
that utterly defeats me.
275
713968
1982
12:07
I have to telephone my 25-year-old sons
276
715950
3014
12:10
and ask them to talk me through it
277
718964
2197
12:13
while I try to push those wretched 41 buttons.
278
721161
4997
12:18
What can we do to improve the lives of the elderly
279
726158
2647
12:20
in the U.S., and to make better use of their value?
280
728805
3454
12:24
That's a huge problem.
281
732259
1774
12:26
In my remaining four minutes today,
282
734033
2471
12:28
I can offer just a few suggestions.
283
736504
2577
12:31
One value of older people is that they are
284
739081
1922
12:33
increasingly useful as grandparents
285
741003
3444
12:36
for offering high-quality childcare
286
744447
2507
12:38
to their grandchildren, if they choose to do it,
287
746954
2653
12:41
as more young women enter the workforce
288
749607
2849
12:44
and as fewer young parents of either gender
289
752456
2334
12:46
stay home as full-time caretakers of their children.
290
754790
3660
12:50
Compared to the usual alternatives
291
758450
2036
12:52
of paid babysitters and day care centers,
292
760486
3598
12:56
grandparents offer superior, motivated,
293
764084
3127
12:59
experienced child care.
294
767211
2688
13:01
They've already gained experience
from raising their own children.
295
769899
3266
13:05
They usually love their grandchildren,
296
773165
2344
13:07
and are eager to spend time with them.
297
775509
2665
13:10
Unlike other caregivers,
298
778174
1901
13:12
grandparents don't quit their job
299
780075
2897
13:14
because they found another job with higher pay
300
782972
2436
13:17
looking after another baby.
301
785408
3513
13:20
A second value of older people is paradoxically
302
788921
2404
13:23
related to their loss of value
303
791325
2661
13:25
as a result of changing world
conditions and technology.
304
793986
4073
13:30
At the same time, older people have gained
305
798059
2036
13:32
in value today precisely because
306
800095
2311
13:34
of their unique experience of living conditions
307
802406
3109
13:37
that have now become rare
308
805515
1719
13:39
because of rapid change, but that could come back.
309
807234
3310
13:42
For example, only Americans now in their 70s
310
810544
2954
13:45
or older today can remember
311
813498
2260
13:47
the experience of living through a great depression,
312
815758
3328
13:51
the experience of living through a world war,
313
819086
2638
13:53
and agonizing whether or not
314
821724
2546
13:56
dropping atomic bombs would be more horrible
315
824270
3037
13:59
than the likely consequences
of not dropping atomic bombs.
316
827307
4113
14:03
Most of our current voters and politicians
317
831420
2276
14:05
have no personal experience of any of those things,
318
833696
2732
14:08
but millions of older Americans do.
319
836428
2695
14:11
Unfortunately, all of those terrible situations
320
839123
2651
14:13
could come back.
321
841774
1387
14:15
Even if they don't come back,
322
843161
1306
14:16
we have to be able to plan for them
323
844467
2192
14:18
on the basis of the experience of what they were like.
324
846659
2811
14:21
Older people have that experience.
325
849470
1834
14:23
Younger people don't.
326
851304
2053
14:25
The remaining value of older people
327
853357
1520
14:26
that I'll mention involves recognizing that
328
854877
2443
14:29
while there are many things that older people
329
857320
2580
14:31
can no longer do,
330
859900
1606
14:33
there are other things that they can do
331
861506
1489
14:34
better than younger people.
332
862995
2095
14:37
A challenge for society is
to make use of those things
333
865090
2896
14:39
that older people are better at doing.
334
867986
2472
14:42
Some abilities, of course, decrease with age.
335
870458
3249
14:45
Those include abilities at tasks
336
873707
2638
14:48
requiring physical strength and stamina,
337
876345
3571
14:51
ambition, and the power of novel reasoning
338
879916
3124
14:55
in a circumscribed situation,
339
883040
2425
14:57
such as figuring out the structure of DNA,
340
885465
2588
15:00
best left to scientists under the age of 30.
341
888053
3901
15:03
Conversely, valuable attributes
342
891954
1649
15:05
that increase with age include experience,
343
893603
3546
15:09
understanding of people and human relationships,
344
897149
3013
15:12
ability to help other people
345
900162
2291
15:14
without your own ego getting in the way,
346
902453
2428
15:16
and interdisciplinary thinking about large databases,
347
904881
3525
15:20
such as economics and comparative history,
348
908406
2825
15:23
best left to scholars over the age of 60.
349
911231
3214
15:26
Hence older people are
much better than younger people
350
914445
2472
15:28
at supervising, administering, advising,
351
916917
3971
15:32
strategizing, teaching, synthesizing,
352
920888
3482
15:36
and devising long-term plans.
353
924370
2706
15:39
I've seen this value of older people
354
927076
2020
15:41
with so many of my friends in their 60s,
355
929096
2572
15:43
70s, 80s and 90s,
356
931668
1990
15:45
who are still active as investment managers,
357
933658
3285
15:48
farmers, lawyers and doctors.
358
936943
3013
15:51
In short, many traditional societies
359
939956
2130
15:54
make better use of their elderly
360
942086
2113
15:56
and give their elderly more satisfying lives
361
944199
3110
15:59
than we do in modern, big societies.
362
947309
2850
16:02
Paradoxically nowadays,
363
950159
1865
16:04
when we have more elderly people than ever before,
364
952024
2926
16:06
living healthier lives and with better medical care
365
954950
2721
16:09
than ever before,
366
957671
1486
16:11
old age is in some respects more miserable
367
959157
2707
16:13
than ever before.
368
961864
1767
16:15
The lives of the elderly are widely recognized
369
963631
2422
16:18
as constituting a disaster area
370
966053
2767
16:20
of modern American society.
371
968820
2533
16:23
We can surely do better by learning
372
971353
1681
16:25
from the lives of the elderly
373
973034
1875
16:26
in traditional societies.
374
974909
2012
16:28
But what's true of the lives of the elderly
375
976921
1942
16:30
in traditional societies
376
978863
1464
16:32
is true of many other features
377
980327
1695
16:34
of traditional societies as well.
378
982022
2594
16:36
Of course, I'm not advocating that we all give up
379
984616
2589
16:39
agriculture and metal tools
380
987205
2115
16:41
and return to a hunter-gatherer lifestyle.
381
989320
3084
16:44
There are many obvious respects
382
992404
1544
16:45
in which our lives today are far happier
383
993948
2479
16:48
than those in small, traditional societies.
384
996427
3062
16:51
To mention just a few examples,
385
999489
1706
16:53
our lives are longer, materially much richer,
386
1001195
2970
16:56
and less plagued by violence
387
1004165
2283
16:58
than are the lives of people in traditional societies.
388
1006448
3228
17:01
But there are also things to be admired
389
1009676
2528
17:04
about people in traditional societies,
390
1012204
2142
17:06
and perhaps to be learned from them.
391
1014346
2319
17:08
Their lives are usually socially much richer
392
1016665
2591
17:11
than our lives,
393
1019256
1592
17:12
although materially poorer.
394
1020848
2292
17:15
Their children are more self-confident,
395
1023140
2952
17:18
more independent, and more socially skilled
396
1026092
2594
17:20
than are our children.
397
1028686
2336
17:23
They think more realistically
about dangers than we do.
398
1031022
3743
17:26
They almost never die of diabetes, heart disease,
399
1034765
3529
17:30
stroke, and the other noncommunicable diseases
400
1038294
3234
17:33
that will be the causes of death of almost
401
1041528
2512
17:36
all of us in this room today.
402
1044040
3086
17:39
Features of the modern lifestyle
predispose us to those diseases,
403
1047126
4010
17:43
and features of the traditional lifestyle
404
1051136
2234
17:45
protect us against them.
405
1053370
2507
17:47
Those are just some examples of what we can learn
406
1055877
2159
17:50
from traditional societies.
407
1058036
2288
17:52
I hope that you will find it as fascinating

ABOUT THE SPEAKER
Jared Diamond - Civilization scholar
Jared Diamond investigates why cultures prosper or decline -- and what we can learn by taking a broad look across many kinds of societies.

Why you should listen

In his books Guns, Germs and Steel and Collapse (and the popular PBS and National Geographic documentaries they inspired), big-picture scholar Jared Diamond explores civilizations and why they all seem to fall. Now in his latest book, The World Until Yesterday, Diamond examines small, traditional, tribal societies -- and suggests that modern civilization is only our latest solution to survival.
 
Diamond’s background in evolutionary biology, geography and physiology informs his integrated vision of human history. He posits that success -- and failure -- depends on how well societies adapt to their changing environment.
