Question

1. what is the significance of mutations in the process of evolution? a. they are harmful and lead to extinction b. they have no impact on evolution c. they provide new genetic variations for natural selection to act upon d. they ensure all traits are preserved 14. what does convergent evolution demonstrate? a. diverse adaptations in similar environments b. similar traits evolving due to similar environmental pressures c. dispersal patterns in biogeography d. common ancestry among species 15. mutations serve as the ultimate source of: a. species diversity b. microevolution c. genetic diversity d. environmental adaptation

Explanation:

1. Mutations create new genetic variations which are raw materials for natural - selection. They are not always harmful and don't ensure all traits are preserved.
2. Convergent evolution is when similar traits evolve in different species due to similar environmental pressures.
3. Mutations are the ultimate source of genetic diversity as they introduce new genetic material.

Answer:

1. c. They provide new genetic variations for natural selection to act upon
2. b. Similar traits evolving due to similar environmental pressures
3. c. Genetic diversity
