Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as Homo erectus , Denisovans , and Neanderthals as well as modern forms, and evolved worldwide to the diverse ...
Until 2014, the Standard Grade section of the site had 12 subjects: Biology, History, Chemistry, Computing Studies, Maths, English, Modern Studies (a course exclusive to Scotland), French, Physical Education, Geography, and Physics. [9] The site was updated in 2014 to replace the Standard Grade section with National 4 and National 5 sections.
The Incredible Human Journey is a five-episode, 300-minute, science documentary film presented by Alice Roberts, based on her book by the same name. The film was first broadcast on BBC television in May and June 2009 in the UK.
Brian tells the story of how our innate human curiosity has led us from feeling that we are at the center of everything, to our modern understanding of our true place in space and time – that we are living 13.8 billion years from the beginning of the universe, on a mere speck of rock in a possibly infinite expanse of space.
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately seven million years, [ 1 ] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
This was somewhat surprising since the present day effective population size of humans is estimated to be only ~10,000. If true that means that the human lineage would have experienced an immense decrease of its effective population size (and thus genetic diversity) in its evolution. (see Toba catastrophe theory) A and B are two different loci ...
