why are there still monkeys?
kodėl jos vis dar egzistuoja?
and not a monkey
o ne beždžionės
to understanding where we came from.
iš kur mes atsiradome.
evolutionary biology classes in the US,
evoliucinės biologijos kursų JAV,
why I call them fish all the time,
kodėl juos nuolat vadinu žuvimis,
by dispelling some hardwired myths,
tam tikrų įsišaknijusių mitų išsklaidymo,
many of us were taught evolution wrong.
buvome mokomi apie evoliuciją klaidingai.
to say "the theory of evolution."
„evoliucijos teorija“.
and just like the process itself,
ir, visai kaip pats procesas,
are the ones that survive to this day.
išlieka iki šių dienų.
is Darwinian natural selection.
Darvino natūraliosios atrankos teorija.
that best fit an environment
labiausiai prisitaikę prie aplinkos,
slowly die off.
pamažu išmiršta.
and it's a fact.
ir ji yra faktas.
as much as the "theory of gravity."
kaip „gravitacijos teorija“.
with other placental mammals,
ir kiti placentiniai žinduoliai,
with other vertebrates,
ir kiti stuburiniai gyvūnai,
with all other life on earth.
bet kuri kita gyva būtybė Žemėje.
from different ancestors
ne tik mums.
how we learn biology early on, is it?
ar ne?
are primitive things,
yra primityvūs organizmai,
followed by reptiles and mammals,
vėliau ropliai ir žinduoliai,
at the end of the line.
linijos gale.
portrayed something like this,
vaizduojama taip:
to becoming us.
link tapimo mumis.
any more than we would become them.
kaip ir mes netampame jais.
evolution the right way?
teisingai suvokti evoliuciją?
has led to many problems,
sukėlė daug problemų,
evolution the right way.
to many convoluted and corrupted views
sudėtingų ir iškreiptų nuomonių,
other life on earth,
su kitomis gyvybėmis Žemėje,
we all came from.
iš kurio mes visi atsiradome.
to other single-celled life,
kita vienaląstė gyvybė,
the Archaea and Bacteria
kad archėjos ir bakterijos,
to be here well after us.
multicellularity evolved.
išsivystė daugialąsčiai organizmai.
and your plants and your animals.
a backbone were fishes.
buvo žuvys.
all vertebrates are fishes,
visi stuburiniai gyvūnai yra žuvys,
the mammals and reptiles.
žinduoliai ir ropliai.
some mammals become primates,
kai kurie žinduoliai tampa primatais,
tampa beždžionėmis su uodegomis,
including a variety of human species.
įskaitant įvairias žmonių rūšis.
neišsivystėme iš beždžionių,
a common ancestor with them.
around us kept evolving:
nuolat vystėsi:
lots of fish, fish, fish.
daugybė žuvų, žuvų, žuvų.
yes, they're my favorite group.
taip, jos mano mėgstamiausia grupė.
for a few million years.
keletą milijonų metų.
that we see around us today
mus supančių šiandien,
kaip mūsų rūšis.
it's self-centered to think,
egocentriška manyti,
for an evolutionary minute,
an unfinished book for sure.
be abejo, neužbaigtą knygą.
few pages of each chapter.
kiekvieno skyriaus puslapių.
on the eight million species
four billion years of evolution.
keturis milijonus metų evoliucijos.
on this ancient and gigantic tree of life,
ant seno, milžiniško gyvybės medžio,
not just to each other,
ne tik vieni su kitais,
and our evolutionary ancestors.
ir evoliuciniais protėviais.
trying to learn, with others,
kartu su kitais mokytis,
who is related to whom.
kas giminingas kam.
as a little fish out of water.
žuvį, išmestą ant kranto.
ir kalbėti,
a lot of learning to do
ir iš kur atsiradome.

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.
