Speciation

Definition

noun, plural: speciations

The process in which new genetically distinct species evolve usually as a result of genetic isolation from the main population.


Supplement

Due to Genetic Isolation, the differences in gene pools among species become so great that they cannot reproduce through interbreeding. As a result, new species are formed with a genome that is genetically distinct from the main population.

The ways in which new species are formed are as follows:


Word origin: from Latin speciēs, a seeing, kind, form + L -ātiōn- (s. of -ātiō), action or process.
Related forms: speciate (verb), speciational (adjective).


See also: Genetic isolation.

mutations and dependencies

... shows neo-darwinian 'evolution' to be a myth. Someone is welcome to take it by religious faith, but it is not science. BTW natural selection and speciation both reduce genetic diversity. Natural selection is horribly, horribly misrepresented by cult leaders (Dawkins et al).

Re: Creationism is not scientific

... same things over and over. As I have already stated, creationists actually accept microevolution, and in the last 20 years they now accept that speciation occurs, of course before this they denied these things exists. Creationists are known for moving goal posts.

Creationism is not scientific

... proves it never happened.” How so? “Again we are dealing with a process that has NEVER BEEN OBSERVED.” Not true. See “Observed Instances of Speciation” at talkorigins.org. I’ll point out that speciation by polyploidy is a common observation, mostly in plants but also in lizards (and others?), ...

Is evolution as simple as we think?

... most of the early eukaryotes appeared only after the oxygenation of the atmosphere around 2 billion years ago and this finally sped up the rate of speciation to a completely new level.

Creationism is not scientific

... myths is 'spamming'. 'There is tonnes of evidence for evolution which he ignores.' Which definition of 'evolution'? Change in gene frequency? Speciation? Descent with modification? Genetic drift? Any change in any living thing ever? The myth that the most complex thing man has ever obtained ...
