However the observed selection did not generate an evolutionary response in antler size over the study period of nearly 30 years, and there was no evidence of a positive genetic correlation between antler size and fitness nor of a positive association between breeding values for antler size and fitness. (bioone.org)

Our results are consistent with the hypothesis that a heritable trait under directional selection will not evolve if associations between the measured trait and fitness are determined by environmental covariances: In red deer males, for example, both antler size and success in the fights for mates may be heavily dependent on an individual's nutritional state.

While enormously popular during the early nineteenth century as an explanation for the complexity observed in living systems, after publication of Charles Darwin 's theory of natural selection , the importance of individual efforts in the generation of adaptation was considerably diminished. (newworldencyclopedia.org)
Yet, essentially there is universal agreement among scientists that evolution by natural selection is the fundamental model that explains the extraordinary complexity and interdependence of the living world. (evolutionnews.org)
Moreover, evolution by natural selection is a quintessential scientific theory, explaining an extraordinary collection of data, including much that Darwin himself was unaware of, with a small collection of powerful ideas. (evolutionnews.org)
Of course, it is not true that "essentially there is universal agreement among scientists" about evolution by natural selection. (evolutionnews.org)

Non-Darwinian evolution is any mechanism which tends to downplay the role of natural selection in evolution . (rationalwiki.org)
Non-Darwinian evolution was proposed because many scientists did not believe natural selection was powerful enough to explain evolution . (rationalwiki.org)
Bowler, who has written The Eclipse of Darwinism: anti-Darwinian evolutionary theories in the decades around 1900 (1983), has described a period called the eclipse of Darwinism which discusses the state of affairs prior to the neo-Darwinian synthesis , when evolution was widely accepted in scientific circles, but relatively few biologists believed that natural selection was its primary mechanism. (rationalwiki.org)
Instead of natural selection, scientists in this period were advocating other non-Darwinian mechanisms, such as orthogenesis , neo- Lamarckism , vitalism , or saltationism. (rationalwiki.org)
Most scientists of this period did not deny natural selection , they just said it either has no role in evolution or only has a minor role as a mechanism. (rationalwiki.org)
They were largely abandoned when population genetics and the modern evolutionary synthesis demonstrated the explanatory power of natural selection. (rationalwiki.org)
It is only concerned with denying or downplaying the "Darwinian" mechanisms of evolution, such as natural selection or sexual selection . (rationalwiki.org)
In the early 1900s, there was a near-universal tendency to accept evolution while rejecting Darwin's central premise: natural selection. (rationalwiki.org)
However, scientists who advocate the neo-Darwinian synthesis have reconciled all of these genetic mechanisms with natural selection within a Darwinian framework. (rationalwiki.org)
Non-Darwinian evolution is in opposition to the neo-Darwinian synthesis , which ascribes a central role to natural selection . (rationalwiki.org)

In a wider context, Lamarckism remains of use when examining the evolution of cultures and ideas, is generally held in terms of some religious views on karma and inheritance of sin , and remains applicable to some extent for bacteria and microorganisms . (newworldencyclopedia.org)
Lamarck developed two laws to explain evolution: the law of use and disuse (that use of an organ strengthens and develops it and disuse weakens and deteriorates it), and the law of inheritance of acquired characteristics (that acquisitions or losses fostered by nature on an individual are passed on through reproduction to offspring).
