why are there still monkeys?
niçin hâlâ maymunlar var?
and not a monkey
to understanding where we came from.
anlamak için gerçekten önemli.
evolutionary biology classes in the US,
derslerinden birine giriyorum
why I call them fish all the time,
balık dediğimi en sonunda anladıklarında
by dispelling some hardwired myths,
bilinenleri ortadan kaldırarak başlıyorum,
many of us were taught evolution wrong.
çoğumuz evrimi yanlış öğrendik.
to say "the theory of evolution."
demek öğretildi.
and just like the process itself,
ve sürecin kendi de buna dâhil,
are the ones that survive to this day.
günümüze kadar gelmiş olanlar.
is Darwinian natural selection.
Darwin'in doğal seçilimi.
that best fit an environment
en iyi şekilde uyum sağlayan organizmalar
slowly die off.
yavaş yavaş yok olurlar.
and it's a fact.
ve bu tamamen gerçek.
as much as the "theory of gravity."
teorisi'' kadar gerçek.
memelilerle ortak özelliğiniz
with other placental mammals,
with other vertebrates,
paylaştığınız omurganıza
with all other life on earth.
ortak olan DNA'nıza bakabilirsiniz.
birden ortaya çıkmadı.
from different ancestors
how we learn biology early on, is it?
öğrenmiyoruz, değil mi?
are primitive things,
ilkel olduklarını öğreniyoruz,
followed by reptiles and mammals,
sonra sürüngen ve memeliler geldi,
at the end of the line.
evrilmiş canlı var.
takip ederek evrim geçirmez
portrayed something like this,
böyle bir şey olduğu gösteriliyor,
to becoming us.
bir düzlem üzerindeler.
any more than we would become them.
onlar da bize dönüşmüyor.
evolution the right way?
has led to many problems,
pek çok soruna yol açtı,
evolution the right way.
anlamadan soramazsınız.
to many convoluted and corrupted views
tüm diğer yaşama ilişkin
other life on earth,
bakış açısına sebep oldu,
we all came from.
tek hücreli organizma.
to other single-celled life,
yaşama olanak sağladı
the Archaea and Bacteria
tür olduğunu söylüyor.
to be here well after us.
devam edecekleri kesin.
multicellularity evolved.
çok hücrelilik evrim geçirdi.
and your plants and your animals.
ve hayvanlar da dâhil.
a backbone were fishes.
all vertebrates are fishes,
tüm vertebralar aslında balık,
the mammals and reptiles.
memeliler ve sürüngenlere imkân sağladı.
some mammals become primates,
memelilerin bir kısmı da primat,
including a variety of human species.
içine alan büyük apelere dönüştü.
biz maymunlardan evrilmedik
a common ancestor with them.
around us kept evolving:
evrim geçirmeye devam etti:
lots of fish, fish, fish.
ve çok sayıda balık.
yes, they're my favorite group.
onlar benim en sevdiğim grup.
bir yandan da nesiller tükeniyor.
for a few million years.
birkaç milyon yıl hayatta kaldılar.
that we see around us today
gördüğümüz hayatın büyük kısmı
it's self-centered to think,
for an evolutionary minute,
an unfinished book for sure.
bir kitap olarak düşünün.
few pages of each chapter.
son birkaç sayfasını görüyoruz.
on the eight million species
four billion years of evolution.
bir evrim süreci olduğunu düşünün.
on this ancient and gigantic tree of life,
genç yaprakları olarak hayal edin,
not just to each other,
yalnızca birbirimize değil,
and our evolutionary ancestors.
ve evrimsel atalarımıza bağlıyız.
trying to learn, with others,
hâlâ herkesin birbirleriyle
who is related to whom.
öğrenmeye çalışıyorum.
as a little fish out of water.
olarak düşünmek çok daha iyi.
a lot of learning to do

Why you should listen
Dr. Prosanta Chakrabarty is an Associate Professor and Curator of Fishes at the Museum of Natural Science and Department of Biological Science at Louisiana State University.
Chakrabarty is a systematist and an ichthyologist studying the evolution and biogeography of both freshwater and marine fishes. His work includes studies of Neotropical (Central and South America, Caribbean) and Indo-West Pacific (Indian and Western Pacific Ocean) fishes. His natural history collecting efforts include trips to Japan, Australia, Taiwan, Madagascar, Panama, Kuwait and many other countries. He has discovered over a dozen new species including new anglerfishes and cavefishes.
The LSU Museum of Natural Science fish collection that Chakrabarty oversees includes nearly half a million fish specimens and nearly 10,000 DNA samples covering most major groups of fishes. He earned his PhD at the University of Michigan and his undergraduate degree is from McGill University in Montreal. He has written two books including A Guide to Academia: Getting into and Surviving Grad School, Postdocs and a Research Job. He is also a former Program Director at the National Science Foundation. He was named a TED Fellow in 2016 and a TED Senior Fellow in 2018.
