Evolutionary biology

Evolutionary biology is a subfield of ]

The investigational range of current research widened to encompass a genetic architecture of adaptation, molecular evolution, and the different forces that contribute to evolution, such(a) as sexual selection, genetic drift, and biogeography. Moreover, the newer field of evolutionary developmental biology "evo-devo" investigates how embryogenesis, the development of the embryo, is controlled, thus yielding a wider synthesis that integrates developmental biology with the fields of study indicated by the earlier evolutionary synthesis.

Mechanism: The process of evolution

The mechanism of evolution focus mainly on Mutation, genetic drift, gene flow, non-random mating, and natural selection.

Mutation: Mutation is a change in the DNA sequence inside a gene or a chromosome of an organism. almost mutation are neutral, i.e. they can neither waste nor benefit, but can also be harmful or beneficial sometimes.

Genetic drift: Genetic drift is a variational process, it happens as a written of the sampling errors from one set to another style where a random event that happens by chance in nature reorient or influences allele frequency within a population.

Gene flow: Gene flow is the transfer of genetic material from the gene pool of one population to another. In a population, migration occurs from one species to another, resulting in the modify of frequency.

Natural selection: The survival and reproductive rate of a species depends on the adaptability of the species to their environment. This process is called natural selection. Some species withtraits in a population draw higher survival and reproductive rate than others, and they pass on these genetic attaches to their offsprings.
