Question

A founding population of lizards arrives on an island. Which type of isolation would most likely result in this population becoming a new species?

temporal
geographical
anatomical
behavioral

Answer 1

The answer is Geographical isolation 

Answer 2

Geographical isolation

Step-by-step explanation:

Geographical isolation may be defined as the separation of species due to the geographical barrier. This isolation prevents the species to reproduce from the original population and leads to speciation.

The founding population of lizard has arrived on an island. The lizard is geographically isolated from the main population. Hence, geographical isolation is responsible for the formation of new lizard species.

Thus, the correct answer is option 2.
