Phylogeny: How We're All Related: Crash Course Biology #17
Crocodiles, and birds, and dinosaurs—oh my! While classifying organisms is nothing new, phylogeny— or, grouping organisms by their evolutionary relationships—is helping us see life in a whole new light. In this episode of Crash Course...

The Missing Link That Wasn’t
The myth of the Missing Link--the idea that there must be a specimen that partly resembles an ape but also partly resembles a modern human--is persistent. But the reality is that there is no missing link in our lineage, because that’s...

What Did the First Animal Look Like?
If you trace your way back along the tree of life, eventually you'd come face-to-face with the very first animal. But what exactly would that animal have looked like?

The Secret of Regeneration in... Alligators
Why can amphibians, fish and even some reptiles regenerate limbs, while birds and mammals can’t? Researchers think they might have found a clue on the tip of the alligator’s tail.

Protists
Paul Andersen surveys organisms in the protists. He reviews the diversity found within the domain Eukarya and explains that the Kindgom Protista is simple a junk drawer for organisms that don't fit elsewhere.

Cladograms
Paul Andersen shows you how to construct a cladogram from a group of organisms using shared characteristics. He also discusses the process of parsimony in cladogram construction. He then explains how modern cladograms are constructed and...

Solving the 70 Million Year “Gap” in Flower Evolution
More than 90% of the plants on Earth are angiosperms, flowering plants whose seeds are enclosed inside fruit. And they’re everywhere -- but exactly how and when these plants came to be so ubiquitous is one of the most stubborn questions...

Cladistics Part 1: Constructing Cladograms
Before we dive into learning about all the different kinds of animals, we have a little bit of work to do. How do we describe the relationships between animals? How does phylogeny work? We have to learn about cladistics, which means we...
