Anatomy of a Culex adult. Culex is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis, and avian malaria.
Anatomically modern humans evolved from archaic humans in the Middle Paleolithic, about 200,000 years ago. The emergence of anatomically modern human marks the dawn of the subspecies Homo sapiens sapiens, i.e. the subspecies of Homo sapiens to which all humans alive today belong.
Blumenbach considered the skulls of the Georgians to be the epitome of the white race, and he named the first class of humans after the country's home in the Caucasus Mountains. Blumenbach's class of Caucasians included most Europeans, Northern Africans, and Asians as far east as the Ganges Delta in modern India. As more scientists pursued racial classification in the 1800s, they relied on Blumenbach's nomenclature, cementing the region's legacy in anthropology.
