BioEE1780 Fall 2011 Evolution and Biodiversity Today’s lecturer: Irby Lovette Lecture 4: August 31, 2011 Natural Selection Leaving a legacy is a life’s work This lecture links closely to Ch. 3 sections 3.1 through 3.5 (pages 72-94) in our textbook. We won’t have time to cover textbook section 3.5 (pages 90-94) in detail today, but please read that section of the textbook and think a bit about its implications. Sections 3.6 and 3.7 are not required reading for this class, although you may find them interesting as background material. Post-lecture study suggestion: read closely the textbook description associated with Figure 3.15. This figure presents information that goes one step beyond the case study of natural selection in Darwin’s finches covered in lecture. You should be able to explain why there was a different pattern of beak size evolution on Isla Daphne during the 2003-04 drought than seen in the famous drought of two decades earlier. How had the selective environment changed in the meantime?
