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.
A cell manages to form a rod shape, There is only one example of the more general subject of how a cell develops any shape, have dominated the study of bacterial morphology. An object has coccoid shapes.
The usefulness of bacterial form is further supported by two evolutionary theories. Earliest, shape has a vector through evolutionary time, with coccoid species deriving at the extremities of evolutionary lines and rod-like animals emerging first. A characteristic that develops gradually suggests that selective factors are at work. Second, prokaryotes from various genealogies may morphologically converge, suggesting that having a similar shape may be advantageous in some circumstances. In light of this, a variety of morphological differences can be seen in the Archaea, despite having a cell wall made of non-peptidoglycan.
