Question

The diagram shows the colonization of an island habitat that has never been occupied by a particular species of beetle. Which statement regarding the diagram is true?

the beetles on the island have higher rates of mutation due to their isolation and mutants always have a natural selective advantage
the beetles on the island have a greater amount of genetic variety than the original population of that species of beetle (stabilizing selection)
the one beetle that was introduced to the island is the common ancestor of all of the beetles of that species on the island showing founder effect (genetic drift)
the beetle species on the island shows a case of disruptive selection and increasing genetic diversity
fast

Answer 1

the one beetle that was introduced to the island is the common ancestor of all of the beetles of that species on the island showing founder effect (genetic drift)
