1. Evolutionary Ecology

2. Species Numbers - 2012 What’s missing?

3. A new phylogeny – without prokaryotes

4. From Wilson, 1992

7. Bird Adaptations

8. Evolution Evolution simply means change and biological evolution can be defined as changes in any attribute of a population over time Evolutionary changes that lead to adaptation must involve a change in the frequency of individual genes in a population from generation to generation

9. Adaptation – process which leads to survival and reproduction of characteristics beneficial to an organism in a particular environment Parus caeruleus

10. Perfect Adaptation? Hmm…

11. Charles Darwin Age 46

12. Alfred Russel Wallace – in his 70’s

13. Evolution by Natural Selection 1. Individuals in a population of a species are not identical. 2. At least some of this variation is heritable. 3. All populations have very high reproductive potential, but they seldom achieve it. Mortality and less than maximum reproductive rate keeps them from taking over the earth - e.g. oysters 4. Different individuals leave different numbers of descendents. - this is where idea of fitness comes in 5. The number of descendents an individual has, depends on the interaction between the characteristics of the individual and its environment.

14. Two major points about natural selection 1. Variation among individuals arises due to chance mutations. 2. Individuals survive in today's environment because it is similar to their ancestors environment - adaptation is not planned or purposeful

15. What is selected? The individual is selected.
