Species: Difference between revisions

Different species are capable of breeding with each other, though the offspring are often infertile. Such mingling between species can be frowned upon in some societies, while being completely acceptable in others. Similarly, it is not unheard of for relationships to develop between biologically incompatible individuals, who may either consider alternative methods such as adoption or simply accept childlessness. The ability for some species to create fertile, viable offspring with others has led to academic circles in certain nations proposing that they are different variants of the same species, similar to dog breeds, and not separate species per the biological principle of speciation. Others still propose that speciation is refuted by the presence of these multispecies crosses. A list of known crossbreeding outcomes can be expanded below.
