mechanism of spaciation
Answers
Speciation or the formation of species or phylogeny is the process by which biological populations evolve to become distinct species, as well as a divergent species into two or more species of offspring species. Species formation has been observed many times under controlled conditions both in the laboratory and in the wild [2]. Species-formation phenomena play an important role in the theory of delta balance, involving models in fossil trails for short-lived "bursts of evolution" interrupting long periods of stability, when species change little [3].
According to this theory, species formation and rapid evolution are linked, with natural selection and genetic manipulation most powerful in organisms that undergo species formation in new or isolated species. small populations. As a result, stable cycles in the fossil record for the original population and organisms subject to species change and rapid evolution are found in small populations or geographically restricted areas. and thus rarely being preserved as fossil species [4].
