In which type of speciation does a new species evolve from an ancestral species while inhabiting the same area as the ancestral species?
- A. Allopatric
- B. Sympatric
- C. Convergent
- D. Peripatric
Correct Answer: B. Sympatric
Explanation
The correct answer is sympatric. Speciation often occurs after a group of individuals becomes geographically isolated from its original population, as occurs in allopatric and peripatric specition. In parapatric speciation, there is a very small overlap in the area of the diverging population during and after speciation. In sympatric speciation, a new species evolves without the individuals ever leaving the area of the ancestral species. Convergent is a type of evolution where two different species adapt similar phenotypes.
