Question

How could you distinguish between a species in which there is a lot of variation and two separate species?

Answer 1

 Is there gene flow between the two groups? If there is, they are variants within a population. If there isn't, they are two distinct populations -- species.

Answer 2

It is possible to distinguish between a species in which there are a lot of variations and two species by analyzing DNA sequences.

What is sequence homo-logy?

Sequence homo-logy makes reference to the similarity between DNA sequences of two different organisms.

• The linear order of nucleotides in DNA sequences can be used to distinguish species.

• There are regions in the DNA molecule that exhibit more variation between species than within a species, which can be used to separate different species.

In conclusion, it is possible to distinguish between a species in which there are a lot of variations and two species by analyzing DNA sequences.
