Fossils and Extinction

Unlock the full lesson!

There are 2 supporting pieces of evidence for evolution: Fossils and Antibiotic Resistance. In this video we look at the first of those, fossils. We look at how fossil are formed, how they are used to tell us about evolution and why the fossil record is incomplete. We then look at extinction and factors that might cause the extinction of a species. We finish with plenty of exam questions to practise this topic which frequently comes up in GCSE exams.
