Question

What is the function of speciation

Answer 1

Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.[1][2][3] Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book The Origin of Species.[4] He also identified sexual selection as a likely mechanism, but found it problematic.

There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments. Whether genetic drift is a minor or major contributor to speciation is the subject matter of much ongoing discussion

Answer 2

Did you know there is a lizard that squirts blood out of its eye to deter predators? And, there is a fish that can breathe air on land for several days? There are some bizarre species out there, that's for sure. The diversity of species on Earth is simply astounding. Scientists have identified about two million species and still do not know how many species inhabit Earth. Scientists estimate as many as 30 million species may inhabit Earth. So, the big question is how did so many species form?

A species is a group of individuals that are genetically able to mate in nature and produce fertile offspring. The process of evolution has given rise to the diversity of species we see on Earth. Evolution is a process that explains how organisms have diversified and descended from earlier forms of organisms over time. Essentially that means all species living on earth have derived from a common ancestor. Speciation is an evolutionary process that leads to the formation of a new species.
