Mutation, Natural Selection, Migration, and Genetic Drift.
genetic drift, mutation, natural selection, and migration
The Bantu migration covered a large expanse of the African government of the African continents, this fact makes it an important migration.
Migration refers to the movement of individuals from one population to another, leading to gene flow between populations. This can introduce new genetic variation, impact the genetic diversity of populations, and drive shifts in allele frequencies over time.
There are two theories on the first inhabitants of the Philippines. One is the theory of evolution and another, the theory of migration. In the theory of migration, it is believed that Filipinos came from migrating groups of people from other Asian tribes that came to the islands via land bridges. In the theory of evolution, it is believed that Filipinos today underwent a long process of evolution from Negritos and Malays.
Organic evolution is the process by which the genetic makeup of a species changes over time. There are several mechanisms by which this can happen: natural selection, genetic drift (chance), migration and mutation. So natural selection is one possible way in which evolution can take place. Most biologists agree that natural selection is the most important mechanism of evolution. This mechanism was first discovered by Charles Darwin and, independently. by Alfred Wallace.
Yes
it isn't
forced migration
Without mutation there can be no evolution. Without evolution there can be no speciation.
