Mosquitoes and an evolved taste for humans

In a recent study published in BMC Biology, Dr. Frank Jiggins and his team at the university of Cambridge uncovered the evolutionary history of mosquito migrations and domestication events.

The group found that human-feeding Ae. aegypti mosquitos from an urban population in Senegal, West Africa, were more closely related to populations in Mexico and Sri Lanka than they were to a nearby forest population that fed on animals.

Dr. Jiggins and his team believe that an ancestral population of Ae. aegypti evolved into a human specialist, thus, giving rise to a subspecies known as aegypti aegypti. It is thought that this population migrated out of Africa, therefore explaining why there are such similarities between distant Asian and American populations.
