The rap guide to evolution

Darwin Got It Going On:

The lyrics are, for the most part, witty, sophisticated and scientifically accurate; and they lack the earnest defensiveness that sometimes haunts lectures on evolution. I spotted one or two small slips — a confusion of the praying mantis with the Australian redback spider (oh no!) — and there are a few moments of poetic license that a po-faced pedant might object to. Otherwise, it’s pretty rigorous.
