Question

Shared similarity of genetic flows (e.g. mutations)

a-Provides further evidence of common descent
b-Cannot yet be explained by evolutionary biologists, but will likely be explained some day
c-Does not occur
d-Helps identify symptoms of infections disease

Answer 1

Shared similarity of genetic flows, such as mutations, a) provides evidence of common descent and plays a role in human evolution through gene flow and migration. Hence, a) is correct.

Step-by-step explanation:

Shared similarity of genetic flows, such as mutations, provides further evidence of common descent. Mutations are changes to an organism's DNA that drive diversity in populations and contribute to the accumulation of genetic differences over time.

When two distantly related organisms randomly share a high percentage of DNA bases in the same locations, computer-based statistical algorithms can help identify the actual relationships between them.

Gene flow and migration also play a significant role in human evolution, as they introduce new genetic material to populations. The current level of globalization allows genes to flow between populations across the globe.
