Stephen Jay Gould (/ ɡ uː l d / GOOLD; September 10, 1941 – May 20, 2002) was an American paleontologist, evolutionary biologist, and historian of science.He was one of the most influential and widely read authors of popular science of his generation. [1]
The evolutionary biologist Stephen Jay Gould revived earlier ideas of heterochrony, alterations in the relative rates of developmental processes over the course of evolution, to account for the generation of novel forms, and, with the evolutionary biologist Richard Lewontin, wrote an influential paper in 1979 suggesting that a change in one ...
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 term strongly suggests natural selection, yet Spencer saw evolution as extending into realms of sociology and ethics, so he also supported Lamarckism. [1] [2] Spencer developed an all-embracing conception of evolution as the progressive development of the physical world, biological organisms, the human mind, and human culture and societies ...
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
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.
He then apparently dropped the whole topic for some reason, possibly Charles Lyell's caution: the brief abstract Darwin sent to Asa Gray on 5 September made no mention of sexual selection or human evolution. [38] Wallace, responding to Darwin's 1 May letter, [29] discussed his own theorising. Darwin replied on 22 December that he was "extremely ...
A nomological notion of human nature – "Human nature is the set of properties that humans tend to possess as a result of the evolution of their species." [ 95 ] Machery clarifies that, to count as being "a result of evolution", a property must have an ultimate explanation in Ernst Mayr 's sense.
