Simian. The simians, anthropoids, or higher primates are an infraorder ( Simiiformes / ˈsɪmi.ɪfɔːrmiːz /) of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders Platyrrhini (New World monkeys) and Catarrhini, the latter of which consists of the family Cercopithecidae ( Old ...
The evolutionary history of the primates can be traced back 57-90 million years. [ 1] One of the oldest known primate-like mammal species, Plesiadapis, came from North America; [ 2] another, Archicebus, came from China. [ 3] Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and ...
At its height, the territory occupied by the Tribe of Simeon was in the southwest of Canaan, bordered on the east and south by the tribe of Judah; the boundaries with the tribe of Judah are vague, and it seems that Simeon may have been an enclave within the west of the territory of the tribe of Judah.

Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as the simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; however, in the broader sense based on cladistics, apes ...
History of HIV/AIDS. False-color scanning electron micrograph of HIV-1, in green, budding from cultured lymphocyte. AIDS is caused by a human immunodeficiency virus (HIV), which originated in non-human primates in Central and West Africa. While various sub-groups of the virus acquired human infectivity at different times, the present pandemic ...
And the newly studied fossils represent an earlier hobbit who was 2.4 inches (6.1 centimeters) shorter than the first specimen. Homo erectus was the first ancient human to migrate out of Africa ...
Simians are thus distinctly closer related to tarsiers than lemurs are. Strepsirrhines bifurcated some 20 million years earlier than the tarsier - simian bifurcation. However, simians are traditionally excluded, rendering prosimians paraphyletic. Consequently, the term "prosimian" is no longer widely used in a taxonomic sense, but is still used ...
The Simians originated in Asia while the crown simians were in Afro-Arabia. [ 7][ 8][ 4][ 9][ 10] It is indicated approximately how many million years ago (Mya) the clades diverged into newer clades. In this tree, Eosimiidae as conventionally defined, shown as italic, is a paraphyletic, 'grade' or stem group in this assessment.
