Question

…………………. are two main factors required for the speciation to take place in a population

• A. Climatic changes and nutrition changes
• B. Geographic isolation followed by natural selection
• C. Reproductive isolation
• D. Both B and C

Answer 1

The correct option is D

Both B and C

Speciation is the branching off of individuals from the species they originally were. Over time, as natural selection occurs, individuals may build up adaptations that are no longer compatible with others in their species. This is most often due to geographic isolation or reproductive isolation from other individuals within the species.
