Rocks erode and sediment is deposited.
No sediment is deposited over a long time
Explanation:
Unconformity can form when rocks erode and sediment is deposited in that process, it can also be a period of non-deposition for a very long time. Unconformity represents a time break in the stratigraphic record.
- There are different types of unconformity.
- Unconformity is due to a period of non-deposition or series of erosion which is followed by deposition of sediments.
- Usually, they are expressed by the presence of unconformable beds or some prolonged erosional surfaces that are preserved.

Mutation is a source but it is not the main source after it comes recombination in which 2 chromosomes with “normal” survival are taken from natural population of Drosophila and combined. Then comes immigration of genes in which the new chromosome mix in with different gene frequencies.
The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
