in which of following speciation occur at fastest rate- crow, parrots, and tortoise. why?
Dear student,
Speciation is the process in which one or more species arise from previously existing species. A single species may give rise to a new species or two different species may give rise to a new species. The rate at which speciation occurs is different for different kinds of organisms and therefore it is assumed that it could be as a result from species or clade specific factors, these factors influence the rate at which populations acquire reproductive isolation. If we talk about the list of given organism - the clade of organisms which has higher capacity of reproductive isolation and also have possess traits which are favourable and enable it to survive in the changing environmental conditions, will also undergo speciation at a faster rate as compared to other species. The Parrots are best fitted here in all conditons.
Regards.
