How did one species produce so many different species (the six ecomorphs)? a. because the islands were isolated for an extended period, a lack of interbreeding between populations of the same species caused all the species to diverge. b. without competition from other species, the one species adapted to fit all of the available habitat types. c. to fill all the needed jobs in their ecosystem properly, anolis lizards diverged into exactly the amount of species necessary for their habitat. d. because the anolis lizards have such a diverse range of characteristics, they were able to produce many different species. submit for grading save and finish later?
