This video description is brought to you by language. But how long have humans been able to use our gift of gab? The answer is a lot more complicated than you might think. From studying fossil brains and ear bones to DNA migration...

How and why the giraffe's neck emerged in the first place has been a mystery that generations of biologists have argued over – one that has made us reconsider our understanding of how evolution actually works over and over again.

Today, humans live on just a few staple crops, like maize, rice, and wheat. But in the early days of agriculture, humans were domesticating foods left and right. Come with us as we discover the lost crops of North America, like pitseed...

It’s not nature versus nurture—it’s both! In this episode of Crash Course Biology, we’ll explore how complex interactions between genes and the environment shape all sorts of traits, from human skin color to honeybees’ “royal jelly.”

From a single-celled common ancestor, evolution has brought us all of Life’s Greatest Hits — including butterflies, beetles, bacteria, and human beings. In this episode of Crash Course Biology, we’ll learn how evolution explains life’s...

Explore the concept of biological evolution with the Amoeba Sisters! This video mentions a few misconceptions about biological evolution before providing a general definition. Then this video provides a description of four different...

Do new traits in evolution happen slowly, or all at once? Two new studies in the journal Science may finally help us solve this mystery.

Did our most famous fossil ancestor, Lucy, die by falling out of a tall tree? The answer is part of a decades-long debate over how, exactly, our ancestors transitioned from life in the trees to life on the ground.

Synapsids were the world’s first-ever terrestrial megafauna but the vast majority of these giants were doomed to extinction. However some lived on, keeping a low profile among the dinosaurs. And now our world is the way it is because of...

Bats pretty much appear in the fossil record as recognizable, full-on, flying bats. And they show up on all of the continents, except Antarctica, around the same time. So where did bats come from? And which of the many weird features...

Early primates not only lived in North America -- our primate family tree actually originated here! So what happened to those early relatives of ours?

In the quest to understand how evolution basically built the woolly mammoth, we may have found the blueprints for building them ourselves.

As a scientific concept, evolution was revolutionary when it was first introduced. With the help of all three of our hosts and the Smithsonian National Museum of Natural History’s new Deep Time Hall, we’ll try to explain how evolution...

Lots of the traits we think of as defining us as mammals show up pretty early, during the time of the dinosaurs. And, in some cases, they show up a lot earlier and in things that weren’t mammals at all.

Only a handful of Denisovan fossils have been identified. In the absence of actual body fossils, it’s impossible for us to reconstruct their morphology, right?

Could humans ever evolve to have wings? Why don’t fish have propellers? Why don’t tigers have wheels? Why don’t zebras have laser turrets? These might all seem like stupid questions (and maybe they are!) but they can teach us a lot about...

Explore how to solve Punnett squares that involve sex-linked traits, specifically focusing on X-linked traits. Video has a resource available hereref='https://www.amoebasisters.com/handouts' target='_blank' rel='nofollow'>here This...

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!

Today on SciShow we bring you a cool humanoid diving robot and insight into the evolution of the venus flytrap.

Some online quizzes would have you believe the idea that certain people have a specific “personality type”. But is an “addictive personality” a real thing?

Hank delves into the scientific reasons behind why we are attracted to the people we're attracted to. It's complicated.

SciShow explains the genetics -- and physics -- behind why blue eyes are blue, and what the future may be for the trait. Spoiler alert: Blue eyes aren’t really blue! SciShow explains!
