BIOL 3200 Lecture Notes - Lecture 7: Genetic Drift, Species Problem
Document Summary
Things to know for midterm: know about fischer and what he did, know about specialization. What is modern evolutionary synthesis: neo-darwinism was not accepted initially. Julian huxley: wrote a book (cid:272)alled (cid:862)e(cid:448)olutio(cid:374): the moder(cid:374) (cid:455)(cid:374)thesis(cid:863) in 1942, griffith was doing his experiments in 1942, world war ii was going on in britain in 1942. Specialization: specialization was not simply division of labour because they were competing. Ernst mayr: was a neo-lamarckian but then became a neo-darwinian. Morgan: he was initially a saltationist, he believed mutations drove evolution i(cid:374) so(cid:373)e (cid:272)o(cid:374)te(cid:454)ts this is true. Evolution redefined: evolution is a change in the genetic constitution of populations, by the 70s everyone was a darwinian, darwin said that the only way a population evolves is by frequency changes in the population.
