Episode 3 — History in the rocks

&tAmmonoidsAnti-evolution forces like to make a lot of noise about fossils, in particular about how we don’t have a continuous set of fossils showing every step in the evolution of every species on the planet. What they’re misunderstanding is that it’s hard to make a fossil in the first place — and harder still to guarantee you’ll find it even if it survives for long (the Earth is a pretty big place, after all).

So this episode is all about fossils — how they’re made, why there are occasional “gaps” in the fossil record, and the interesting way in which culture and mindsets have shaped our view of fossils over the years.
