Document Summary

Note: total marks possible being 40 (+2 for bonus); answers will be judged on content and thought, not length!!! The terms adaptation and natural selection are often discussed together; define these terms and discuss the interrelationship between them. Can define adaptation according to hochachka as modification of the characteristics (physiological, biochemical) of organisms that facilitate an enhanced ability to survive and reproduce in a particular environment fitness (1. 5 marks). Darwin is a process of molding an organism so that favorable mutations tend to be retained in a population based upon the existing environment as those individuals with these mutations survive and produce the next generation (1. 5 marks). These two are interrelated whenever we discuss the relationship between the environment and reproduction, as it is natural selection that selects those individuals that survive and reproduce and thus those traits that facilitate this are adaptive.
