The most logical conclusion based on the information provided in the passage is that the other species of cichlids most likely developed because they a) separated within the lake and adapted to different environments. The passage mentions that Lake Victoria was colonized by one species and suggests that the different species likely arose due to adaptation to varying environments within the lake.
Read the passage about cichlids. Lake Victoria, located in East Africa, holds over 200 species of cichlids. Cichlids are a type of fish with a unique "second" jaw in their throat. Wildlife biologists believe that Lake Victoria was initially colonized by one species of cichlid. These facts suggest that other species of cichlids most likely developed because they a separated within the lake and adapted to different environments. b ate all the available prey in Lake Victoria, removing resources. c adapted when the environment was stable for a long period of time. d went through artificial selection, which changed their genotypes.
