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] This process involved the gradual development of traits such as human bipedalism, dexterity ...
Andries van Wezel (31 December 1514 – 15 October 1564), latinised as Andreas Vesalius (/ v ɪ ˈ s eɪ l i ə s /), [2] [a] was an anatomist and physician who wrote De Humani Corporis Fabrica Libri Septem (On the fabric of the human body in seven books), what is considered to be one of the most influential books on human anatomy and a major advance over the long-dominant work of Galen.
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 . It includes brief explanations of the various taxonomic ranks in ...
Polygenism. Polygenism is a theory of human origins which posits the view that the human races are of different origins ( polygenesis ). This view is opposite to the idea of monogenism, which posits a single origin of humanity. Modern scientific views find little merit in any polygenic model due to an increased understanding of speciation in a ...
Last universal common ancestor. The last universal common ancestor ( LUCA) is the hypothesized common ancestral cell from which the three domains of life, the Bacteria, the Archaea, and the Eukarya originated. The cell had a lipid bilayer; it possessed the genetic code and ribosomes which translated from DNA or RNA to proteins.
The aquatic ape hypothesis ( AAH ), also referred to as aquatic ape theory ( AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [ 1] While the hypothesis has some popularity with the lay ...
History of anatomy. Dissection of a cadaver, 15th-century painting. The history of anatomy extends from the earliest examinations of sacrificial victims to the sophisticated analyses of the body performed by modern anatomists and scientists. Written descriptions of human organs and parts can be traced back thousands of years to ancient Egyptian ...
Early modern human. Early modern human ( EMH ), or anatomically modern human ( AMH ), [ 1] are terms used to distinguish Homo sapiens (the only extant Hominina species) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species. This distinction is useful especially for times ...
