Answer:
Darwin observed the Galapagos finches had a graded series of beak sizes and shapes and predicted these species were modified from one original mainland species.
Darwin called differences among species natural selection, which is caused by the inheritance of traits, competition between individuals, and the variation of traits.
Offspring with inherited characteristics that allow them to best compete will survive and have more offspring than those individuals with variations that are less able to compete.
Large-billed finches feed more efficiently on large, hard seeds, whereas smaller billed finches feed more efficiently on small, soft seeds.
When small, soft seeds become rare, large-billed finches will survive better, and there will be more larger-billed birds in the following generation; when large, hard seeds become rare, the opposite will occur.
The next bone healing stage is called the hard callus<span> stage.This transformation occurs when bone forming cells called osteoblasts travel across the </span><span>soft callus.</span>
