Development of Evolutionary Theory Second Week

Agenda n General –Section change –Essay due n Review n Discussion of History of Evolutionary Thought n Summary

Introduction n Four Fields n Forensics n Paleoanthropology –Osteology –Paleopathology n Primatology n Scientific method

Discussion of Chapter

History n Enter Evolution EnterEnter

Understanding Natural Selection n Produce offspring faster than food n biological variation n more are produced than can survive n selective advantage n environmental context n inherited traits n long time periods n geographic isolation

Sickle Cell Exercise n Natural Selection n After selection n In a malarial environment n Balanced or stabilized selection

Natural Selection n Operates on individuals n Populations evolve n Adaptations n Criteria –inherited trait –variation in inherited traits –differential reproductive success-fitness

Next Tuesday n Model due n Bring lab books n Chapters 3 and 4
