 However, Guadeloupean anoles exhibit high individual variability and the populations widely intergrade, something that possibly has been enhanced by habitat changes by humans (allowing populations to easier come into contact with each other) and translocations of individuals.This indicates that the subspecies are invalid today.Genetic studies confirm that strong assortative mating between the different Guadeloupean anole populations does not exist, despite their distinct differences in appearance and them having separated about 650,000 years ago (confidence interval starting at 351,000 years).
