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.
Beginning of animal evolution. [54] [55] 720–630 Ma Possible global glaciation [56] [57] which increased the atmospheric oxygen and decreased carbon dioxide, and was either caused by land plant evolution [58] or resulted in it. [59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...
It shows a sequence of figures, drawn by natural history painter and muralist Rudolph Zallinger (1919–1995). [4] The 15 human evolutionary forebears are lined up as if they were marching in a parade from left to right. The first two sentences of the caption read "What were the stages of man's long march from apelike ancestors to sapiens ...
The sequence divergence has generally the following pattern: Human-Chimp < Human-Gorilla << Human-Orangutan, highlighting the close kinship between humans and the African apes. Alu elements diverge quickly due to their high frequency of CpG dinucleotides which mutate roughly 10 times more often than the average nucleotide in the genome.
Natural selection – Mechanism of evolution by differential survival and reproduction of individuals Sexual selection – Mode of natural selection involving the choosing of and competition for mates; Mutation – Alteration in the nucleotide sequence of a genome; Gene flow – Transfer of genetic variation from one population to another
