In 1751, Pierre Louis Maupertuis wrote of natural modifications occurring during reproduction and accumulating over many generations to produce new species.Georges-Louis Leclerc, Comte de Buffon suggested that species could degenerate into different organisms, and Erasmus Darwin proposed that all warm-blooded animals could have descended from a single microorganism (or "filament").Not everything over there is fully functional yet, and the internal links still point to this blog, and will for the indefinite future.So all the old material will be left here for archival purposes, with comments turned off.
This teleonomy is the quality whereby the process of natural selection creates and preserves traits that are seemingly fitted for the functional roles they perform. In the early 20th century the modern evolutionary synthesis integrated classical genetics with Darwin's theory of evolution by natural selection through the discipline of population genetics.
The importance of natural selection as a cause of evolution was accepted into other branches of biology.
Moreover, previously held notions about evolution, such as orthogenesis, evolutionism, and other beliefs about innate "progress" within the largest-scale trends in evolution, became obsolete.
In each generation, many offspring fail to survive to an age of reproduction because of limited resources.
This could explain the diversity of plants and animals from a common ancestry through the working of natural laws in the same way for all types of organism.
