Lake Malawi in Africa is home to about 200 species of allopatrically speciated cichlid fish. However, recent development around the lake is reducing the visabiliy in the lake, and as a result recently diverged species are merging back together. Why?

Lake Malawi in Africa is home to about 200 species of allopatrically
| A) |
Because the geneflow between species has been reduced due to the reduction in visability |
|
| B) |
Because those species have not evolved a second reproductive isolation mechanism in addition to sexual selection |
|
| C) |
Because the open water habitat is no longer as habitable, so the open water species are now using the bottom habitat |
|
| D) |
Because the bottom habitat is no longer habitable, so the bottom habitat species are not using the open water habitat, leading to more hybridization |
