If two groups remain separated for a long time and cannot reproduce with each other, which process can this be linked to?
Answer and explanation
Correct answer: Speciation
Speciation is the evolutionary process through which one population becomes separated into distinct species. Long-term isolation can reduce gene flow, while different variations accumulate in the separated groups. If they eventually cannot successfully interbreed, reproductive isolation has formed, providing an important condition for species separation. Therefore option A, speciation, is correct. Digestion, respiration and blood clotting are physiological processes and do not describe the formation of distinct species.
