Answer:
Evolution
Step-by-step explanation:
Adaptation can be define as the process by which organisms or species adapts and become fitted into its ecological environment. It is an aftermath effect of natural selection taking it place on heritable variation over an extended period of generation.
Genetic recombination porpularly termed as genetic reshuffling is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent. This leads to production of hybrid species.
Evolution is the change in the heritable characteristics of a biological population of a species over several generations and relies on the process of natural selection. This theory is based on the idea that all species are related to fitness and gradual change over time.
This makes option B the right answer.
In biology, a mutation is the alteration of the nucleotide sequence of the genome of an organism and extrachromosomal DNA. They serve as tools in evolution.
Mitosis is a type of cell division giving rise in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
