Evolution Misconceptions: video worksheets, differenriated.

This engaging PBS film explains at 12 commonly misunderstood phenomena in evolution: mutations are random, but selection is not; silent crickets of Kauai, then later Oahu, both phenotypes arising from selection pressure but via different mutations; the evolution of complex eyes; genetic drift and reproductive isolation – speciation of mosquitos on the London Underground system; tetrapods’ recurrent laryngeal nerve; nipples on male mammals; evolution can work against entropy because earth is not a closed system; remnant DNA from various sources; if humans evolved from monkeys, then why are there still monkeys? Retention of LCT gene in adults; evolutionary pressure ‘bypassed’ by medicine; coelacanth – when the environment doesn’t change, there’s little evolutionary pressure.
