MCQ on Speciation with Answers (PDF)







Speciation is the evolutionary process through which new biological species arise. It occurs when populations of a species become reproductively isolated from each other, leading to the accumulation of genetic differences over time. Speciation can occur through various mechanisms, including allopatric, sympatric, parapatric, and peripatric speciation, each influenced by ecological, behavioral, and geographic factors. This is an MCQ on Speciation with Answers. You can download the quiz as PDF from the results page.
