Adaptive Landscape

A surface plotted in a 3-dimensional graph; with all possible combinations of allele frequencies for different loci plotted in the plane, and mean fitness for each combination plotted in a third dimension.

Investigating cancer and its proliferation through genetic changes and ignoring the adaptive landscape is most likely futile.
Wright's (1931) adaptive landscape is the inspiration for peaks of adaptation on our adaptive landscape.
Because of the complexity of majority-minority relations in all of their permutations, and because of the difficulty or even impossibility of designing successful ethnic strategies in the constantly changing adaptive landscape, Salter is appropriately humble about his analysis; the case presented is "anything but complete".
An adaptive landscape method was used to study a combination of the relative number of tines and relative tine length.
Note that this is different from an "adaptive landscape" over a space of phenotypic characters (Simpson 1944; Lande and Arnold 1983).
This idea dates to the 1930s, when evolutionary theorist Sewall Wright suggested evolution could be viewed as occurring on what he called an "adaptive landscape." Specific collections of genes, or genotypes, endow organisms with traits that help determine their adaptive fitness -- how well they can withstand the selection pressures in their environments.
Multi-peaked adaptive landscape for chikungunya virus evolution predicts continued fitness optimization in Aedes albopictus mosquitoes.
This idea has remained well-entrenched, even with recent recognition that hominin origins took place in a woodland environment and that the adaptive landscape in Africa fluctuated dramatically in response to short-term climatic shifts.
However, the question remains about the accuracy in the initial mimetic signal required for the evolution across the valley of low fitness intermediates in the adaptive landscape.
