Hace 3 días · Evolutionary biology. On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) [3] is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology.
Hace 4 días · Charles Darwin (born February 12, 1809, Shrewsbury, Shropshire, England—died April 19, 1882, Downe, Kent) was an English naturalist whose scientific theory of evolution by natural selection became the foundation of modern evolutionary studies.
Hace 1 día · Abstract. Natural selection is differential reproduction. Demographic and ethnographic, historical and genetic evidence suggest that, over the course of our evolutionary past, members of H. sapiens varied in reproductive success. Selection for emotions and other adaptations underlying intrasexual and intersexual competition should have been strong.
Hace 5 días · Natural selection is a fundamental mechanism of evolution proposed by Charles Darwin. It is based on the observation that individuals within a population exhibit variation in their traits. Some of these variations are heritable, meaning they can be passed on to offspring.

The balance between these two types of selection can shift rapidly in response to environmental changes.
9 de may. de 2024 · 10 May 2024. Genetic variation is essential for evolutionary change. Over a few generations, variation within populations can be used to predict how traits evolve under natural selection. However, how such microevolution translates into macroevolution, or change over many thousands or millions of years, is less clear.
