Adaptation is both an evolutionary process and a product of natural selection: adaptation is a process of evolution in which traits are modified by natural selection; an adaptation is a phenotypic trait moulded by natural selection. In both cases the evolution is driven by natural selection.关键词...

For a one locus n-allele genetic model of natural selection two theoretical predictions are obtained: first, that the non-equilibrium average fitness value, W( t) is always between the equilibrium value, W, and WH(p o, p) t until finally W(t) = W and, secondly, that the area bounded...

By understanding natural selection, we can learn why some plants produce cyanide, why rabbits produce so many offspring, how animals first emerged from the ocean to live on land, and how some mammals eventually went back again. We can even learn about microscopic life, such as bacteria andviru...
5 points of natural selection Population have genetic variations Some variations are favorable. More offspring are produced than survive Those that survive have favorable traits (advantageous) A population will change over time Mutation Changes in the DNA of organisms Can be cause by radiation/chemicals...
The effects of adult crowding on two components of fitness were studied in three sets of Drosophila melanogaster populations, subjected to life-stage-specific, density-dependent natural selection in the laboratory for over 50 generations. Three days of crowding, early in adult life, were observed to...
(Haldane, 1949; Figure 1). Haldane hypothesized that these disorders had become common in these regions because naturalselectionhad acted to increase the prevalence of traits that protect individuals from malaria. Just a few years later, Haldane's so-called "malaria hypothesis" was confirmed ...
A largely verbal theory of evolution which maintains that the interaction between natural selection, genetic drift and migration is more important that the action of any single force. Sewall Wright argued that this theory helped to explain how species could effectively search for the global, and not...
