This short feature points out that evolutionary "tree charts" aren't really fact.

- So, we could organize it as simplest to most complex. Or by color.
- 00:17
- See, organization just is not my thing. Once my little sister asked me to organize all her little tiny plastic animals, it took me two days.
- 00:25
- Organizing animals. It's like Carl Linnaeus. Who's that? Yeah, he was the first guy to classify animals.
- 00:32
- Oh, oh, yeah, I remember him now. His motto was, God created, Linnaeus ordered.
- 00:39
- Yeah, his work is the basis for the classification system we still use today. Later, Charles Darwin sketched a diagram to show how life started simple and then branched out to every creature on Earth.
- 00:50
- He said the different branches represent the different levels of classification. A tree of life, if you will.
- 00:56
- Oh yeah, I keep seeing this over and over again in our textbooks. Really? Yeah. Here we go, check out this one.
- 01:08
- Are researchers still trying to figure out how it happened? There are a lot more of these diagrams.
- 01:13
- I think they change as different researchers group them based on different features.
- 01:19
- These charts show groups of organisms they believe share a common ancestor. Yeah, a group like that is called a clade.
- 01:26
- And these diagrams are called cladograms. Hmm, man, and I thought organizing my makeup was hard.
- 01:35
- So do they. Well, not your makeup, classifying animals. Okay, so remember that modern evolutionary classification is a rapidly changing science with a difficult goal, to present all life on a single evolutionary tree.
- 01:51
- As evolutionary biologists study relationships among taxa, they regularly change not only the way organisms are grouped, but also sometimes the name of groups.
- 02:03
- Remember that cladograms are visual presentations of hypotheses about relationships and not hard and fast facts.
- 02:10
- Whoa, whoa, whoa. You're saying our textbooks say that cladograms are based off hypotheses, not facts.
- 02:18
- Yeah, I'll show you why. Flip forward a page. That's because they only have living animals or fossils for certain places on the branches.
- 02:27
- These are real animals or fossils we've actually discovered. But these branching points are just imaginary lines that represent the hypotheses about which animals evolved from a common ancestor.
- 02:40
- No facts support them that can't also support different links, or no links. The transitional fossils they represent have never been found.
- 02:49
- If they were, well, we'd see their pictures here, right? Though evolutionists point to a few examples, there should be thousands.
