What is the main difference between adaptive radiation and other forms of speciation? According to the biological species concept, for speciation to occur, _____. Allopatric speciation occurs when two different groups of species are formed from the single species. 9th - 12th grade. 0. Tags: Question 27 . Their typical breeding season lasts from January to March. Keywords: reproductive, isolation, post-zygotic, pre-zygotic, behaviors, biodiversity, genes, organisms, mating. The different species are found in the different environments and are separated from each other due to geographical and physiological barriers or variations due to different genetic characters. Reproductive isolation refers to when two or more groups of animals live together or close enough to interact but they are not able to interbreed. Allopatric speciation is when new species arise due to isolation of a population by geographical barriers. Hawaiian honeycreepers, which are found only in Hawaii, have been found to have DNA commonalities with this group of finches that indicate they have a common ancestor.

There are various reasons why organisms cannot mate, which can be divided into two categories: post-zygotic barrier and pre-zygotic barrier. Biodiversity depends on a species' ability to reproduce itself. Amounts of gene flow, and thus the selection required to counter them, form a continuum ranging from absent or low to high and can vary over time and space during the speciation process.
