Question

_________________-new species formed from a small pop isolated at the edge of a larger pop

Answer 1

Answer:

Peripatric speciation

Explanation:

Peripatric speciation usually is an occurrence which happens when a small group of individuals break off of the main group to form a new species. This is similar to allopatric speciation, in this case, the two groups are separated by physical barriers such as mountain ranges or waterways, making it almost impossible for the two groups to interbreed.

There is always a special gene in the smaller group that had been isolated from the parent group. This special gene could allow the particular species to develop thicker fur, longer limbs or even, in extremely rare cases, an entirely new body part.
