While Haeckel's tree is outdated, it illustrates clearly the principles that more complex and accurate modern reconstructions can obscure. 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 ...
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, [40] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
A number of other changes have also characterized the evolution of humans, among them an increased reliance on vision rather than smell (highly reduced olfactory bulb); a longer juvenile developmental period and higher infant dependency; [181] a smaller gut and small, misaligned teeth; faster basal metabolism; [182] loss of body hair; [183] an ...
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
Homo sapiens (red) Expansion of early modern humans from Africa through the Near East. In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) [a] is the most widely accepted [1] [2] [3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).

Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological, medical, historical and forensic implications and applications. Genetic data can provide important insights into human ...
The researchers discovered that while humans have gained about 30 years of life expectancy over the 20 th century, improvements in overall life expectancy have slowed—and actually declined in ...
