Elsewhere in the book we discuss one inquiry (figure $5.33,$ page $169.$ for another, see: This mechanism of biodiversity loss, often termed reverse speciation or introgressive extinction, is of exceptional interest because the parent species are typically highly differentiated ecologically.

A majority of evolutionary biologists now agree that natural selection is the most important mechanism promoting divergence between populations. The primary mechanism for this collapse is thought to be the weakening of ecologically mediated reproductive barriers, as demonstrated in cases of ‘reverse speciation’4,5. Chromosome mutation, where chromosomes break or fuse or duplicate, can cause on the spot speciation, though, by making an organism unable to bred successfully with the parent population.

Reverse speciation events are potentially powerful case studies for the role of evolution in driving ecological changes,. What must be true for allopatric speciation to occur, regardless of the mechanism of separation? Hypotheses regarding how speciation begins differ in the role of geographic isolation and the origin of reproductive isolation (preventing populations from breeding with one another).

The tephritid fruit fly rhagoletis pomonella is an example of ecological specialization and speciation in action via a recent host plant shift from hawthorn to apple.

New species can originate through a number of mechanisms, including geographic isolation (allopatric speciation) and formation of reproductive barriers due to localized natural selection.

This mechanism of biodiversity loss, often termed reverse speciation or introgressive extinction, is of exceptional interest because the parent species are typically highly differentiated ecologically. Genetic mutation doesn’t cause speciation, but it provides raw material (in the form of variation) for natural selection to work on, which eventually leads to.
