One of the theory's central claims is that culture evolves partly through a Darwinian selection process, which dual inheritance theorists often describe by analogy to genetic evolution. [ 3 ] 'Culture', in this context, is defined as 'socially learned behavior', and 'social learning' is defined as copying behaviors observed in others or ...
Dante Gabriel Rossetti, How They Met Themselves, watercolour, 1864. A doppelgänger [a] (/ ˈ d ɒ p əl ɡ ɛ ŋ ər,-ɡ æ ŋ-/ DOP-əl-gheng-ər, -gang-), sometimes spelled doppelgaenger or doppelganger, is a ghostly double of a living person, especially one that haunts its own fleshly counterpart.
Evolutionists expected one part to change at a time, one change to follow another. In Cuvier's view, evolution was impossible, as any one change would unbalance the whole delicate system. [11] Louis Agassiz's 1856 "Essay on Classification" exemplified German philosophical idealism. This held that each species was complex within itself, had ...
The Kuhn-Popper debate was a debate surrounding research methods and the advancement of scientific knowledge. In 1965, at the University of London's International Colloquium in the Philosophy of Science, Thomas Kuhn and Karl Popper engaged in a debate that circled around three main areas of disagreement. [1]
Nature versus nurture is a long-standing debate in biology and society about the relative influence on human beings of their genetic inheritance (nature) and the environmental conditions of their development .
Erasmus Darwin developed a theory of universal transformation. His major works, The Botanic Garden (1792), Zoonomia (1794–96), and The Temple of Nature all touched on the transformation of organic creatures. In both The Botanic Garden and The Temple of Nature, Darwin used poetry to describe his ideas regarding species.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
Charles Darwin's 1859 book, On the Origin of Species, convinced most biologists that evolution had occurred, but not that natural selection was its primary mechanism. In the 19th and early 20th centuries, variations of Lamarckism (inheritance of acquired characteristics), orthogenesis (progressive evolution), saltationism (evolution by jumps) and mutationism (evolution driven by mutations ...
