with researchers using one or a combination of these concepts to convince others they have found a new species, and not just variation within a pre-existing group. Dr Rupert Collins, our Senior ...

Extensive genetic variation is contained within a population of any species and is clearly visible in the domestic dog species, as shown in the photograph below. For example, if a mutation led to ...
