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 linear view of human evolution began to be abandoned in the 1970s as different species of humans were discovered that made the linear concept increasingly unlikely. In the 21st century with the advent of molecular biology techniques and computerization, whole-genome sequencing of Neanderthal and human genome were performed, confirming ...
Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity. With the beginnings of modern biological taxonomy in the late 17th century, two opposed ideas influenced Western biological thinking: essentialism, the belief that every species has essential characteristics that are unalterable, a concept ...
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 ...
Stephen Jay Gould and Richard Lewontin used the architectural term spandrel (the triangular gap at the corner of an arch) to describe a byproduct of evolution. Basilica di San Marco , Venice . In evolutionary biology , a spandrel is a phenotypic trait that is a byproduct of the evolution of some other characteristic, rather than a direct ...
A language model AI created proteins as good as ones honed over a million years of evolution. The implications are staggering. AI Has Successfully Imitated Human Evolution—and Might Do It Even ...
The initial stage, which he dubs the first human evolution, started over two million years ago, defined by humanity’s growing desire to conquer nature. But that phase finally started to decline ...
In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits .
