You knew the question “Which came first, the chicken or the egg? Was hard, but maybe you didn't realize it was so complex. But in three and a half fast-talking minutes Mitchell Moffit and Gregory Brown from AASP Science use the multiple answers to this nearly 2000-year-old question to teach a little about evolution.
You can sort of see why Creationism survives – you don't have to do all this hard thinking, instead just deciding that whichever God happened to make was first. However, Richard Dawkins also takes a simple approach, saying, “The egg of course. The chicken is only an egg's way of making another egg.”
