A major challenge in biology is to understand how species evolve . Today, about 150 years after the publication of Darwin “ On the Origin of Species ” we really still do not understand the process of speciation . This is partly due to the fact that most classical studies of speciation are based on species that have diverged, and therefore, we speculate back in time to infer the causes of speciation . A effet, two of the best known examples of “ sympatric speciation ”, cichlids of Lake Victoria and horseshoe bats of Wallace, suggest that the sensory ecology (how an animal perceives and interacts with its environment) plays a major role in the speciation process, that the populations are geographically isolated or not . However, in these studies, researchers were unable to study the factors involved in the early stages of the process of speciation .
changamoto kubwa katika biolojia ni kuelewa jinsi ya aina kufuka . Leo, kuhusu 150 miaka baada ya kuchapishwa Darwin “ "Sur l'Origine ya ” kweli sisi bado hawaelewi mchakato wa speciation . Hii ni sehemu kutokana na ukweli kwamba masomo zaidi classical ya speciation ni msingi aina ambayo diverged, na kwa hiyo, sisi kubashiri nyuma katika muda wa infer sababu za speciation . En effet, mbili ya mifano bora maalumu ya “ sympatric speciation ”, cichlids ya Ziwa Victoria na popo farasi wa Wallace, zinaonyesha kwamba ikolojia hisia (jinsi mnyama anatambua na interacts na mazingira yake) ina jukumu kubwa katika mchakato wa speciation, kwamba idadi ya kijiografia wametengwa au . Hata hivyo, katika haya masomo, watafiti walikuwa hawawezi kusoma mambo ya kushiriki katika hatua za mwanzo za mchakato wa speciation .
