Laboratory experiments of speciation have been conducted for all four modes of speciation: allopatric, peripatric, parapatric, and sympatric; and various other processes involving speciation: hybridization, reinforcement, founder effects, among others. Most of the experiments have been done on flies, in particular Drosophila fruit flies. However, more recent studies have tested yeasts, fungi, and even viruses.

  • Laboratory experiments of speciation have been conducted for all four modes of speciation: allopatric, peripatric, parapatric, and sympatric; and various other processes involving speciation: hybridization, reinforcement, founder effects, among others. Most of the experiments have been done on flies, in particular Drosophila fruit flies. However, more recent studies have tested yeasts, fungi, and even viruses. It has been suggested that laboratory experiments are not conducive to vicariant speciation events (allopatric and peripatric) due to their small population sizes and limited generations. Most estimates from studies of nature indicate that speciation takes hundreds of thousands to millions of years. On the other hand, many species are thought to have speciated faster and more recently, such as the European flounders (Platichthys flesus) that spawn in pelagic and demersal zones—having allopatrically speciated in under 3000 generations.

  • 종분화에 대한 실험은 잡종화, 강화, 창시자 효과 등 모두에 대해 수행되었다. 대부분의 실험은 파리, 특히 초파리로 이루어졌다. 그러나 더 최근의 연구에서는 효모, 곰팡이, 심지어 바이러스까지도 이용하여 실험했다. 실험실 실험(Laboratory experiment)은 개체군 크기가 작고 세대가 제한되어 있기 때문에 변종 종분화(동종 및 주변)에 도움이 되지 않는다고 제안되었다. 자연 연구에서 얻은 대부분의 추정치는 종분화에 수십만 년에서 수백만 년이 걸린다는 것을 나타낸다. 다른 한편으로, 많은 종은 3000세대 미만에서 동종분화를 하고 있는 원양, 해저 지역에서 산란하는 유럽 가자미(Platichthys flesus)와 같이 더 빠르고 최근에 종분화한 것으로 생각된다.
