Question
DNA evidence indicates that two species of land snails are closely related and may only recently have become distinct species.
What would a biologist infer has happened to the original population of land snails?
Answer options with 4 options
A.
The original snail population became extinct because of environmental changes.
B.
The original snail population had a group of snails that became reproductively isolated.
C.
The original snail population interbred with a different species of snail to form an entirely new species.
D.
The original snail population became too large for the ecosystem so the species adapted by forming a new species.

The best inference a biologist could make regarding what happened to the original population of land snails, given that DNA evidence indicates that two species are closely related and may have only recently become distinct species, is:
**B. The original snail population had a group of snails that became reproductively isolated.**
This option suggests that a subset of the originally interbreeding population became separated in some way, leading to the formation of two distinct species over time due to reproductive isolation.
**B. The original snail population had a group of snails that became reproductively isolated.**
This option suggests that a subset of the originally interbreeding population became separated in some way, leading to the formation of two distinct species over time due to reproductive isolation.
