Question

Identify the order of the steps that lead from isolation to evolution.


The founding population becomes biogeographically isolated from the rest of its species.


Over time, the population becomes reproductively isolated from the original population.


The process begins with a founding population.


The isolated population undergoes genetic change through random mutations.

Answer 1

Correct order:

1. The process begins with a founding population.
2. The founding population becomes biogeographically isolated from the rest of its species.
3. The isolated population undergoes genetic change through random mutations (and other evolutionary forces).
4. Over time, the population becomes reproductively isolated from the original population (leading to speciation).
