Hace 2 días · Natural selection is a mechanism of evolution —not evolution itself. "Natural" refers to how traits are passed on without intentional outside interference. (In contrast, "artificial selection ...

Hace 1 día · Darwin (and others) explained away the destruction of Aboriginal Tasmanians (and others) as simply an effect of natural selection. This logic buttressed the idea that extinct hominids were “primitive” in the same way as Indigenous peoples: that people distant in space or culture were the same as people distant in time.

Hace 2 días · However, it remains unclear how coevolutionary processes translate into the accumulation of species richness over macroevolutionary timescales. Assuming speciation occurs as a result of genetic differentiation across space due to dispersal limitation, we examine the effects of coevolution-induced phenotypic selection on species diversification.
Hace 23 horas · Darwin's central theory of natural selection neither originated nor could be contained, with the parameters of the natural sciences, but continues to shape and challenge our most basic assumptions about human social and political life.Several new readings, crossing the fields of history, literature, sociology, anthropology and history of science, demonstrate the complex position of the text ...
