Our data show that the fitness of the hybrids between the two species is highly dependent on environmental conditions which affect food abundance that is, to what extent hybrids, with their combination of gene variants from both species, can successfully compete for food and territory, said Leif Andersson of Uppsala University and Texas A&M University. The university researchers pasted a link to the survey on the new website. The idea of "selection" is the strongest survive the changes/adaptations that occur within a generation, so that the species evolves and survives between generations. Show more details.
