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.
The March of Progress, [1] [2] [3] originally titled The Road to Homo Sapiens, is an illustration that presents 25 million years of human evolution. It was created for the Early Man volume of the Life Nature Library, published in 1965, and drawn by the artist Rudolph Zallinger. It has been widely parodied and imitated to create images of ...
The hominoids are descendants of a common ancestor.. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [1]
The genus Homo evolved from Australopithecus. [7] The earliest record of Homo is the 2.8 million-year-old specimen LD 350-1 from Ethiopia, [8] and the earliest named species is Homo habilis which evolved by 2.3 million years ago. [9] The most important difference between Homo habilis and Australopithecus was a 50% increase in brain size. [10]
Within Africa, Homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago. [ note 1 ] The recent African origin paradigm suggests that the anatomically modern humans outside of Africa descend from a population of Homo sapiens migrating from East Africa roughly 70–50,000 years ago and spreading along the southern coast ...
"The results for Ranis are amazing," Weiss said, adding that scientists should return to other European sites from this time period to check for similar evidence of an early Homo sapiens presence.
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [39] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
The internodal time span is useful to estimate the ancestral effective population size of the common ancestor of humans and chimpanzees. A parsimonious analysis revealed that 24 loci supported the Homo-Pan clade, 7 supported the Homo-Gorilla clade, 2 supported the Pan-Gorilla clade and 20 gave no resolution. Additionally they took 35 protein ...
