Punctuated Equilibria

This is an old video from 1991 but it does an excellent job of explaining punctuated equilibria. That's because it features Niles Eldridge and Stephen Jay Gould.

There are two important lessons for creationists in this video. Let's hope they learn them.

1. The evidence for punctuated equilibria is based on thousands and thousands of fossils covering millions of years. It required a complete fossil record. It has nothing whatsoever to do with gaps in the fossil record. It's the exact opposite of gaps!

2. Evolution is observed when a single species splits into two species and that takes place over a relatively short period of time. "Relatively short period of time" does not mean that the new species poofs into existence. It means 50,000-100,000 years.

Whenever your creationist friends start lying to you about punctuated equilibria you can ask them to watch this video. You'd think that would stop them from spreading misinformation but then you realize that this video is 20 years old.

Facts don't seem to matter to creationists.1




1. In the interests of fairness, I should note that there are a great many evolutionists who also don't understand punctuated equilibria. I'm really posting this video for them and not for the creationists.
