Fifteen iguanas survived a hurricane on a raft of uprooted trees. After a month at sea, they
colonized an island. They were the first of their species to arrive there. Evolutionary
biologists predict that this group of iguanas could become a new species.
Which statement BEST explains why the iguanas would become a new species?

Answer 1

Reproductive isolation

Step-by-step explanation:

The lack of reproduction among organisms (in this case iguanas) that survived in an island and the original population can lead to the emergence of reproductive barriers between both groups and therefore may eventually lead to speciation

Answer 2

These iguanas will go through the speciation process.

Step-by-step explanation:

Like these iguanas, they were the only ones of their species that managed to reach this island, they will begin to undergo a process of adaptation to the island's environment, which will promote the evolution of their organisms. This evolution will trigger anatomical and even molecular differences that will modify the iguanas, to the point that they can no longer be recognized by the species they represented. Thus generating a new species.
