Speciation, which leads to diversity among species through natural selection occurs when
A. organisms develop characteristics that mimics traits of completely different species.
B. species experience change within their lineage and develop new characteristics
C. species interact with other species in an ecosystem and develop similar traits to each other.
D. once similar species are no longer able to mate and produce fertile offspring.

Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.
