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.
the variety or species of humans that was intermediate between Homo erectus and modern people (Homo sapiens). The first archaic Homo sapiens may have evolved as early as 650,000 years ago, but most lived after 300,000 years ago.The last and most well known of them were the Neandertals, who survived until nearly 28,000 years ago. Archaic Homo sapiens have also been referred to as archaic humans and early Homo sapiens.. very early form of archaic Homo sapiens in Europe and North Africa that lived from about 800,000 to 200,000 years ago. In an alternate interpretation, some researchers consider Homo heidelbergensis to be a separate species. Homo heidelbergensis may have been the ancestor of the Neandertals.
