Which situation can be considered an important step towards formation of a new species?
Answer and explanation
Correct answer: Two groups being unable to breed successfully with each other
A major biological criterion separating species is reproductive compatibility. If two populations can no longer produce viable, fertile offspring with one another, reproductive isolation has developed. This condition may follow the accumulation of genetic and anatomical differences and is an important step toward speciation. Option A is correct. Remaining identical, merging, or having no variation would preserve gene flow or prevent evolutionary divergence rather than promote a new species.
