Question

Traits that are similar in two species as a result of convergent evolution are referred to as:

A) Homologous

B) Analogous

C) Synonymous

D) Both B and C

Answer 1

Ans) The correct answer is "B" i.e analogous

In convergent evolution, the two different species or unrelated species having different ancestors will converge over the time span and such traits which are shared between these two unrelated species are known as analogous traits (same function but different structure).For example birds,flies etc have wings whose structure is different but the function is same i.e for flying.Their ancestors lacked wings but these species have evolved to have this trait for their increased survival.

Wheras in divergent evolution where a common ancestor will diverge into two different species over the time and these species will share homologous traits (same structure but different function).For example humans,bats and whale have 5 digit limbs whose structure is same but functions are different.
