learning about the mechanisms of evolution and have heard and read some of the current research associated with human evolution, how would you respond to the statement “I didn’t come from no ape.”? How would you explain the process of evolution, specifically human evolution, to someone that has not know about evolution?

The popular media often presents evolution as being a predictable process with a definite goal. For instance, in one “Star Trek: Voyager” episode, the captain instructs the ship’s computer to extrapolate the “probable course” of evolution of hadrosaurs (a bipedal dinosaur), if hadrosaurs had been removed from Earth before the Cretaceous-Tertiary (K-T) Extinction and allowed to evolve on another planet. What information about the hadrosaurs’ new environment would have been useful in developing the best possible prediction? Given what you know on genetic drift and selective agents, is it possible to accurately predict the long-term course of evolution?

Paranthropus boisei and Homo neanderthalensis are considered “side branches” of human evolution - these species lived alongside Homo erectus and ancestral populations of Homo sapiens, respectively (see the hominin evolutionary tree on the last page of the handout), but are not thought to have notably contributed to the evolution of modern humans. Compare the anatomical features of the skull in a) Paranthropus boisei vs. Homo erectus and b) Homo neanderthalensis vs. Homo sapiens, and based on these comparisons come up with hypotheses to explain why Paranthropus and Homo neanderthalensis might have gone extinct while Homo erectus and Homo sapiens did not. (Hint: think about climatic factors - try doing some research on your own to determine what was happening with the climate at the time that Paranthropus and Homo neanderthalensis went extinct. Also, think about the various evolutionary mechanisms that we’ve discussed in lecture and lab).

1. What is the difference between the different patternsof selection: directional, stabilizing, anddiversifying?

2. How do bacteria acquire genetic variation and how doesthat differ from the mechanism by which humans acquirevariation?

3. What were the key observations made by Darwin todevelop the basic tenants of the theory of evolution? Has thistheory been tested?

4. What are the most common misconceptions about evolutionand why are they not valid arguments against evolution?

5. The key component of the theory of evolution is naturalselection. Define this process. Why is it commonly known as“survival of the fittest”? What are examples of factors (selectivepressures) that drive evolution of populations?

6. What is the indirect evidence of evolution? What arehomologous and analogous structures? What is convergent evolution?How does similarity of proteins between different species supportthe idea of evolution?

7. Be able to explain why the following statement is true:Natural Selection works on individuals while evolution works onpopulations over generations. Or to put it another way: Individualsdo not evolve, populations do.

8. How can evolution explain the formation of complexstructures such as the eye or the flagella motor?

9. What causes variation in a species? To put this anotherway: all humans have the same genes, yet we do not look alike. Whatis the reason fro the phenotypic differences between individuals ofthe same species? What is genetic recombination?

10. What are the dangers of small populations of a speciesfrom a genetic and evolutionary standpoint? What is the bottleneckeffect?

11. How does speciation occur? What is the importance ofgeographic isolation? How is this illustrated in theGalapagos?

12. What is Darwinian Medicine and how does it help usbetter understand medical conditions?
