Biology - Organisms and Populations Question with Solution | TestHub

Brood parasitism is a type of parasitism in which the parasitic bird lays its eggs in the nest of its host and lets the host incubate them.

During the course of evolution, the eggs of the parasitic bird have evolved to resemble the host's egg in size and colour to reduce the chances of the host bird detecting the foreign eggs and ejecting them from the nest.

In the case of the Asian koel and the Indian crow, the Asian koel is the brood parasite and the Indian crow is the host. Therefore, the eggs of the Asian koel have evolved to resemble the eggs of the Indian crow, not the other way around.

The eggs of the Asian koel also hatch earlier than those of the Indian crow, giving the parasitic chicks an advantage in receiving food.

Hence, the statement that the eggs of the Indian crow have evolved to resemble the Asian koel's eggs is incorrect.

Answer: Eggs of Indian crow has evolved to resemble Asian Koelis eggs to avoid ejection.
