Explain and give examples for each of the following statements about
natural selection (adapted from Freeman and Herron, Evolutionary Analysis, pp.
57-61):
 |
1. |
Natural selection acts on individuals, but it is
populations that evolve. |
|
2. |
Natural selection acts on phenotypes, but its actions
change the allele frequencies in a population. |
|
3. |
The entire individual is the target of selection, not the
individual genes. |
|
4. |
Natural selection can create new traits, even though it
acts on existing traits. |
|
5. |
Natural selection does not lead to perfection, only
adaptation. |
|
6. |
Natural selection is nonrandom, but it does not
necessarily lead to more advanced organisms. |
