Until the early 20th century, Tasmania was home to a very weird wolf-like creature. Except that it wasn't a wolf. Even though it looked like a wolf. How did that happen? Here's the science of convergent evolution!

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...

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...

The nugget explains various evidences that favors organic evolution. Describe the importance of tracing evolutionary relationships.

Natural selection can lead to some pretty amazing adaptations, but sometimes the resulting traits aren’t the most efficient solutions to the problems at hand. With the bar set to “good enough,” here are some features that arose from...

Finding out the appearance of aliens from what we already know about convergent evolution.

Hank introduces us to comparative anatomy, which studies the similarities and differences in animal anatomy to support the theory of evolution and the shared ancestry of living things.

Once evolution finds a trick that works, it tends to repeat it. Here are a few examples of prehistoric animals that look a lot like ones we know today.

This video discusses the fascinating world of raptors, focusing on the two remaining families of primarily nocturnal owls. It explores their evolution from dinosaurs and their unique adaptations for hunting and scavenging. The video...

We may think of a lot of critters with crab-like body plans as crabs, but, technically, many of them are other types of crustaceans. So why do they share so many physical traits?

Because there are so many different types of penises among our evolutionary relatives, we didn’t know until a recent discovery whether they all had the same origin.

How and why does botanical carnivory keep evolving? It turns out that when any of the basic things that most plants need aren’t there, some plants can adapt in unexpected ways to make sure they thrive.

High elevations can be a problem for humans. Since the air is thinner, you get less oxygen with every breath, leading to all kinds of negative side effects. But there are millions of people around the world who spend their whole lives at...

If you spook a spitting cobra, it might literally shoot venom at your eyes... And our ancestors might have caused them to do this, evolutionarily speaking.

There are a lot of ways to kill and be killed in the animal kingdom, but only a lucky few use the powers of venom. Not all are closely related, so how did they acquire the same defenses, where did venom come from, and how does it work?...

The lower Congo River is treacherous, turbulent, and very deep. While that might seem like an inhospitable habitat, hundreds of species of fish thrive there, including some that are really bizarre!SciShow is supported by Brilliant.org.

When there’s only one species on an evolutionary branch, we call it a monospecific taxon. Studying these special species can help us better understand not just those sparse groups, but all life on this planet.

Blood is one of the most revolutionary features in our evolutionary history. Over hundreds of millions of years, the way in which blood does its job has changed over and over again. As a result, we animals have our familiar red blood....

Today, billions of people around the world start their day with caffeine. But how and why did the ability to produce this molecule independently evolve in multiple, distantly-related lineages of flowering plants, again and again?

For some reason, animals keep evolving into things that look like crabs, independently, over and over again. What is it about the crab’s form that makes it so evolutionarily successful that non-crabs are apparently jealous of it?

Join the Amoeba Sisters as they introduce the basics about cladograms and phylogenetic trees. The Amoeba Sisters walk through the process of building a basic cladogram and mention vocabulary such as: shared ancestral character, shared...
