The finches needed to adapt to the different environments and changed all over time so they could survive better.

homologic structures ar features that ar quasi(prenominal) in structure but appear in different organisms and have different functions. For example, in mammals most of the bones are in the same oecumenical place as other mammals. The forelimbs of humans, bats, and moles all have connatural structures even though their forelimbs are us ed for different functions. raise scientist! have discovered margin call that these animals with similar structures have were one time very similar to each other but then they developed over time into more developed species. budding structures are undeveloped or unused features. An example of this in nature is an Ostrich. Today, Ostriches do not use their wings for dissolute but for balance. Ostriches have long bodies and powerful legs which they use to leak from predators.
