These two forces can exert their effects in a time perspective (and spatial). Other mechanisms described, such as migration, are more or less related to prior combining variably and therefore directly influence biological evolution. There is no determinism in the evolution of species, However, all species of bioceonose are interrelated and their physical and biological environment. Relatives environmental conditions or biological interactions of the same kind may therefore promote the development of similar adaptations through a process of convergent evolution.
Utaratibu mwingine ilivyoelezwa, kama vile uhamiaji, ni zaidi au chini ya hapo juu kuhusiana na kuchanganya namna kutofautiana na hivyo kuathiri moja kwa moja kibayolojia . Hakuna utambuzi katika uendelezaji wa asili, Hata hivyo, aina ya bioceonose ni yanayohusiana na mazingira yao ya kimwili na kibiolojia . Jamaa hali ya mazingira au mwingiliano wa kibaiolojia wa asili moja inaweza hiyo kukuza maendeleo ya mchakato sawa marekebisho convergent mageuzi . Mifano ya muunganiko ni nyingi katika falme mbalimbali ya maisha na tafsiri potofu ya madhara yake wakati mwingine ulisababisha makosa katika kutafuta mahusiano phylogenetic ya baadhi ya vikundi .
