Question

which they chose to live.
c genetic variation occurred amongst the finches, giving some a genetic advantage in a changing environment, allowing them to better survive.
d members of the original population evolved in such a way that it became impossible for individuals from the two new populations to interbreed.
part b
a species is a group of individual organisms that interbreed and produce fertile, viable offspring. according to this definition, one species is distinguished from another when, in nature, mating between individuals from each species is not possible to produce fertile offspring. evolution is an important mechanism in the formation of new species. the evolution of a new species requires several components, including all, but
a evolution of a new species requires a change in a population over time.
b evolution of a new species requires individual organisms to evolve during a single lifespan.
c evolution of a new species requires differentiation in individuals.
d evolution of a new species requires variations or mutations that produce new genetic traits.

Explanation:

Evolution is a population - level process. It occurs over generations, not within a single organism's lifespan. A single individual cannot evolve into a new species during its lifetime. Variations (mutations) in the population, differentiation among individuals, and changes in the population over time are all components of speciation.

Answer:

B. Evolution of a new species requires individual organisms to evolve during a single lifespan.
