A species that is well adapted to its current environment expands its geographic range C. A helpful new trait jumps from species to species D. Two formerly Isolated populations come back into secondary contact and produce hybrids that are well adapted to the new environment E. A species diverges into many new descendant species, each in its own ecological niche

Answer 1

Adaptive radiation is a process where a single species diverges and forms different types of species such as the Darwin Finches which diverged when faced with different ecological niches. Hence the correct answer is: E. A species diverges into many new descendant species, each of its own ecological niche.
