What is the ultimate outcome of the process known as speciation?

Two populations learning to share a single environment

The formation of one or more new species from a single ancestral species

An individual organism adapting its physical traits during its lifetime

The temporary separation of a population into two groups

At which point are two separated populations officially considered distinct species?

When they develop different fur colors or body sizes.

The moment they are separated by a physical barrier like a river.

When they can no longer interbreed to produce healthy, fertile offspring.

Once they begin to live in slightly different climates.

It directly causes genetic mutations to increase.

It forces the two groups to have different diets.

It stops gene flow, allowing the groups to evolve independently.

It ensures that both groups become larger in size.

choose to live in separate habitats even when a barrier is removed.

are physically separated by an impassable geographic feature.

can no longer produce viable and fertile offspring with each other.

develop different mating seasons that do not overlap.
