Hank tells us the background story and explains the importance of the science of classifying living things, also known as taxonomy.

Do you like drinking milk or chatting with your friends? Well, you can enjoy those because of the evolution happened over the past million years, and we are still evolving. Let's find out what will we be like in the future with us!

Paul Andersen explains the concept of coevolution. He begins with an analogy comparing the relationship of humans to technology with those of coevolving species. He then discriminates between coevolution and convergent evolution. He...

Paul Andersen discusses the specifics of phylogenetics. The evolutionary relationships of organisms are discovered through both morphological and molecular data. A specific type of phylogenetic tree, the cladogram, is also covered.

During the Cretaceous Period, dinosaurs were more diverse, more fierce, and more strange than ever. But something else was happening under the feet of the terrible lizards: for the first time in history, there were flowers.

This week, science explains the chemical love-connection we share with our dogs, and how some of the most isolated populations of people in the world are different on the inside.

Epigenetic inheritance is really weird, but is it real?

Even cells can be selfish.

Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as chordata. And the next time someone asks you who you are, you can give them the facts: you're a mammalian amniotic tetrapodal...

With the non-avian dinosaurs extinct, it was time for mammals to take over. Finally, in the tiniest sliver of the history of life, humans emerge.

Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern...

Discover what happens when random events meet allele frequencies: genetic drift! This Amoeba Sisters video also discusses the bottleneck and founder effect as well as contrasts genetic drift with natural selection. Table of Contents:...

Birds are known for having beaks, however at what point between being a humongous therapod and tiny sparrow did they get them, and why?

Evolution is particularly vulnerable to misunderstandings around the scientific language. SciShow clears up some confusing language!

Paul Andersen describes three main characteristics of life that are conserved in all organisms on the planet. The universal genetic code, the central dogma of biology, and shared metabolic pathways give us details of the original...

Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

In this hilarious, whirlwind tour of the last four billion years of evolution, paleontologist and TED Fellow Lauren Sallan introduces us to some of the wildly diverse animals that roamed the prehistoric planet (from sharks with wings to...

In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them.

With rising temperatures and seas, massive droughts, and changing landscapes, successfully adapting to climate change is increasingly important. For humans, this can mean using technology to find solutions. But for some plants and...

We know whales as graceful giants bound to the sea. But what if we told you there was actually a time when whales could walk.

For life to evolve on Earth, a bunch of complex organic molecules had to evolve a way to assemble into cells. So how did those proto-cells get cell membranes? Some researchers have a new hunch. Also, scientists are borrowing a trick from...

If gigantic googly eyes make you want to run away, it’s because you are responding to a supernormal stimulus. But what is it, and why our brain responds to it?

Some of the biggest evolution questions finally answered.

"Survival of the Fittest" sounds like a great WWE show but today we're talking about that phrase as it relates to Charles Darwin and Alfred Wallace. Darwin and Wallace are at the heart of understanding evolution and natural selection....
