Contrast allopatric speciation with sympatric speciation, and explain how each method may result in the creation of a new species.
Compare and contrast allopatric and sympatric speciation, and discuss why one is more common than the other.
What is Sympatric speciation?
A) When a population is separated from the main group by a barrier and becomes a new species
B) When a population mutates into a new species
C) When a population develops into a new species without any physical barriers to isolate them

On the other hand, sympatric and parapatric are generated from genetic isolation, which then leads to geographic isolation.arrow_forwardThe type of speciation that takes place in geographically overlapping populations is known as ________________________.

- A physical barrier separates a single species, causing two separate populations to form. Over time these two populations adapt to their environments. Eventually, these two populations are no longer able to successfully reproduce with each other. This is known as __________. A. Sympatric speciation B. Allopatric speciation C.
