Following Darwin's theory of natural selection, we know that species of animals develop certain traits that would enable it to adapt and survive its environment in order to preserve its kind. These special traits are passed down from generation to generation and that's how different species have evolved throughout millions of years. That usually happens because of the context these animals live in and the unique elements found in their environment. But what if you find a whole diverse range of species in the same environment? How could we explain such a phenomenon? This has been what's puzzling biologists studying the cichlids at Lake Malawi. Despite living together in the same environment, they are able to branch off into new species at such a fast rate. And the answer they got is technically quite simple.
