tak proč tu s námi opice pořád ještě žijí?
why are there still monkeys?
a ne opice,
and not a monkey
to understanding where we came from.
pochopit, odkud pocházíme.
o evoluční biologii v USA
evolutionary biology classes in the US,
why I call them fish all the time,
proč jsem jim celou dobu říkal ryby,
by dispelling some hardwired myths,
že vyvrátím některé zakořeněné mýty,
many of us were taught evolution wrong.
hodně věcí, které nás o evoluci naučili,
učili o „evoluční teorii“.
to say "the theory of evolution."
a stejně jako evoluce sama o sobě,
and just like the process itself,
údajům, jsou ty, které přežijí dodnes.
are the ones that survive to this day.
is Darwinian natural selection.
Darwinova teorie přirozeného výběru.
that best fit an environment
který se nejlépe přizpůsobí prostředí,
pomalu vyhynou.
slowly die off.
and it's a fact.
as much as the "theory of gravity."
jako „gravitační teorie“.
with other placental mammals,
with other vertebrates,
with all other life on earth.
živá stvoření na celé planetě.
from different ancestors
nejen my.
how we learn biology early on, is it?
biologii neučíme, že ano?
are primitive things,
jsou primitivní stvoření
followed by reptiles and mammals,
které následovali plazi a savci.
at the end of the line.
na konci řetězce.
portrayed something like this,
která zobrazovala něco takového,
to becoming us.
any more than we would become them.
a my se též nestaneme jimi.
produktem evoluce.
evolution the right way?
has led to many problems,
vedlo k mnoha problémům,
evolution the right way.
to many convoluted and corrupted views
zavádějícím a zcestným názorům
other life on earth,
k ostatním stvořením na zemi
we all came from.
ze kterého jsme se vyvinuli.
to other single-celled life,
vyvinul další jednobuněčný život,
the Archaea and Bacteria
archea a bakterie,
to be here well after us.
multicellularity evolved.
asi před 3 miliardami let.
and your plants and your animals.
i vašich zvířat.
a backbone were fishes.
byly ryby.
all vertebrates are fishes,
všichni obratlovci ryby,
Takže mi neříkejte,
the mammals and reptiles.
savci a plazi.
z některých savců primáti,
some mammals become primates,
including a variety of human species.
včetně různých lidských druhů.
nevyvinuli z opic,
a common ancestor with them.
around us kept evolving:
lots of fish, fish, fish.
všude plno ryb, ryb a ryb.
yes, they're my favorite group.
tak mám ryby nejraději.
druhy také vymírají.
for a few million years.
několik milionů let.
that we see around us today
který nás obklopuje,
it's self-centered to think,
si myslet, že
for an evolutionary minute,
v ten správný okamžik
an unfinished book for sure.
knihu, která ještě není dopsaná.
few pages of each chapter.
stránek z každé kapitoly.
on the eight million species
uvidíte 8 milionů druhů,
four billion years of evolution.
4 miliardy let evoluce.
mladé listy na tomto prastarém a obrovském
on this ancient and gigantic tree of life,
neviditelnými větvemi nejen mezi sebou,
not just to each other,
and our evolutionary ancestors.
a našimi evolučními předky.
trying to learn, with others,
se snažím spolu s ostatními zjistit,
who is related to whom.
a kdo je propojený s kým.
as a little fish out of water.
o malé rybce na suchu.
chodit a mluvit,
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.
