Document Summary
Guest lecture by dr. semple: the human evoluion (no slides provided) Logarithmic change in populaion numbers which will eventually be followed by a crash phase. Dawn of humans homo ergaster homo sapiens. Darwin worried about the public reacion to his evoluionary ideas (on the publicaion of on origin of species) Social darwinism: jusify one"s ethnic group superiority over others based on certain traits. A debate took place between huxely and bishop wilberfone (both were experts on natural sciences). The bishop asked huxely if he has descended from the great ape from his mother"s side or his father"s side. To which huxely replied with something sarcasic that made the public laugh . The real problem with darwin"s ideas were the lack of mechanism (remember he did not know of the concept of genes and inheritance modes) Placental: specialized embryonic organ atached to the wall of the uterus. Synapmorphy of all mammals is that we have mammary glands and hair.
