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.

Paleoanthropologists agree that modern humans evolved in Africa about 200,000 years ago, yet the fossil evidence for the earliest examples of Homo sapiens is scarce.mage courtesy of Wikicommons.
