Speciation is the divergence of two populations from a common ancestor. how does it contribute to biological diversity? (a) speciation increases biological diversity.(b) speciation has no effect on biological diversity.(c) speciation decreases biological diversity.

Option (A)

Explanation: The rate of speciation is directly proportional to the amount of biological diversity. This means that, the more is the speciation, the more will be its diversity.

Speciation is a process that helps us in understanding the evolutionary trend of any species and re-establish the various biodiversities existing on earth.

Thus the correct answer is option (A).

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
