A species of finch has been studied on one of the geographically isolated Galapagos Islands for many years.  Since the island is small, the lineage of every bird for several generations is known.  This allows a family tree of each bird to be developed.  Some family groups have survived and others have died out.  The groups that survive probably have

interbred with other species.

inherited some variations that give the bird advantages.

been attacked by more predators.

GPT-4o mini · Answer

The groups that survive probably have **inherited some variations that give the bird advantages**. In the context of evolution and natural selection, species that survive typically possess traits that are beneficial for their survival and reproduction in their specific environment. These advantageous traits can lead to better adaptation to the local conditions, which increases the likelihood of the group’s survival over generations.
