why are there still monkeys?
защо тогава още има маймуни?
and not a monkey
а не маймуна
to understanding where we came from.
от къде сме произлезли.
evolutionary biology classes in the US,
по еволюционна биология в САЩ
why I call them fish all the time,
защо ги наричам риби постоянно,
by dispelling some hardwired myths,
с развенчаването на улегнали митове,
many of us were taught evolution wrong.
са били обучавани грешно за еволюцията.
to say "the theory of evolution."
"Теория за еволюцията".
and just like the process itself,
и точно като еволюцията,
are the ones that survive to this day.
са тези, които са оцелели до днес.
is Darwinian natural selection.
е Дарвиновият естествен подбор.
that best fit an environment
които са най-годни за средата
slowly die off.
не са годни, бавно отмират.
and it's a fact.
as much as the "theory of gravity."
колкото теорията за гравитацията.
плацентни бозайници,
with other placental mammals,
with other vertebrates,
който е общ за всички гръбначни
with all other life on earth.
с всички живи същества на света.
from different ancestors
how we learn biology early on, is it?
are primitive things,
са примитивни форми,
followed by reptiles and mammals,
влечугите и бозайниците
at the end of the line.
на края на веригата.
portrayed something like this,
изобразена по подобен начин,
to becoming us.
към превръщането си в нас.
any more than we would become them.
повече от колкото ние се превръщаме в тях.
ние не сме целта на еволюцията.
evolution the right way?
правилно?
has led to many problems,
е довело до много проблеми,
evolution the right way.
по правилния начин.
to many convoluted and corrupted views
до много заплетени и изкривени представи
с останалите живи организми на Земята,
other life on earth,
4 милиарда години назад.
we all came from.
от който сме произлезли всички.
to other single-celled life,
други едноклетъчни,
че Археите и Бактериите,
the Archaea and Bacteria
to be here well after us.
multicellularity evolved.
еволюирали многоклетъчните.
and your plants and your animals.
гъби и растения, и животни.
a backbone were fishes.
били рибите.
all vertebrates are fishes,
всички гръбначни са риби,
the mammals and reptiles.
и на бозайниците и влечугите.
some mammals become primates,
някои бозайници примати,
including a variety of human species.
включително човешки видове.
не сме еволюирали от маймуните,
a common ancestor with them.
around us kept evolving:
животът около нас продължил да еволюира:
lots of fish, fish, fish.
множество риби, риби, риби.
yes, they're my favorite group.
да те са ми любимата група.
for a few million years.
по няколко милиона години.
that we see around us today
повечето от живота около нас днес
it's self-centered to think,
и егоистично да мислим:
for an evolutionary minute,
an unfinished book for sure.
със сигурност недонаписана.
few pages of each chapter.
от всяка глава.
on the eight million species
four billion years of evolution.
като четири милиарда години еволюция.
on this ancient and gigantic tree of life,
на огромното древно дърво на живота,
not just to each other,
не само помежду си
and our evolutionary ancestors.
и еволюционни предци.
trying to learn, with others,
заедно с други,
who is related to whom.
и кой с кого е свързан.
as a little fish out of water.
малка риба извън водата.
да ходи и говори,
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.
