Love is blind! Fish in African lake that's so murky they can't recognize their own species create evolutionary boom through accidental inter-species mating Researchers spent ten years studying freshwater fish populations in East Africa They found an unexpected amount of genetic diversity among the fish They believe the diversity was caused by female fish breeding with other species

At first glance, the fish you might see swimming through to waters of Lake Mweru might not look that different.

To scientists studying life in the lake on the border between Zambia and the Democratic Republic of the Congo, the fish population are a model of extraordinary diversity.

This week, researchers published findings from a decade spent researching the fish in Lake Mweru and other freshwater lakes in the region, concluding that their unexpected diversity may have an even more unexpected cause.

Researchers in East Africa found more than 40 species of cichlid fish (pictured above), which they believe evolved in part because females couldn't see who they were mating with clearly in the cloudy and murky lake waters

Under normal conditions, fish prefer to breed with members of their own species, but the murky waters and low light conditions in Lake Mweru and many of the of the region’s other lakes can make it hard for females to see their male partners.
