Q. Why is genetic variation important from an evolutionary standpoint? (Solved)
1. If all organisms were the same, the entire population would be vulnerable to particular pathogens, like viruses.
2. All evolutionary adaptations (e.g. the origin of forelimbs) are the result of the gradual build up of genetic differences between organisms over geologic time.
3. Evolution (at the population level) refers to changes in the frequencies of genes in the population over time.
4. All of the above.
- d. All of the above.
