Question

in which of following speciation occur at fastest rate- crow, parrots, and tortoise. why?

Answer 1

Speciation is a process by which a new species develops from the existing species. Some of the important factors which contribute to speciation include

Geographical isolationGenetic driftNatural selectionAdaptive radiationReproductive isolation

The rate at which speciation occurs varies greatly among different kinds of organisms and is frequently assumed to result from species- or clade-specific factors that influence the rate at which populations acquire reproductive isolation. Organisms that quickly evolve prezygotic or postzygotic reproductive isolation should have faster rates of speciation than organisms that slowly acquire reproductive isolation.

From the organisms listed here- crow, parrot and tortoise, the clade of organism which has higher capacity of reproductive isolation and possess traits which are favorable and enable it to survive in the changing environmental conditions, will undergo speciation at a faster rate as compared to other species. 

Hope you get it right!! :)
