As discussed in the lecture and the reading on the evolutionary approaches to human behaviour, Barrett et al. (2002) state that natural selection is “based on just three premises and their logical consequences”. Please describe in your own words each of these 3 principles of natural selection (marks 6).
We discussed how sexual selection could operate via two different processes. Please state and describe what the 2 forms of sexual selection were called (different terms were used in the reading and lecture, both are acceptable) and for each type of sexual selection provide 2 examples of a feature that has evolved via this process (marks 6).
Discussion of sexual selection predominately focus on sexually selected traits in males. Ever since Darwin, little focus has been on sexually selected traits in females. Describe 4 sexually selected traits in females. At least 2 must be found in humans (8 marks).
