Goodbye Option D: Evolution II

Continuing from my last post, please see below for: D3 Human evolution D4 The Hardy–Weinberg principle D5 Phlogeny and systematics   D3 Human evolution The section starts with a section on carbon dating.

This could possibly be followed with these videos that take ...
