WebAbstract. Human evolution and ecology analyses argue that environment is a major factor influencing biological and sociocultural adaptation, but they rarely analyze environmental properties. Multiple problems of perspective and method can arise from the normative and nondynamic environmental descriptions which pervade these analyses. The results so far have shown that if the standing cultural variation in a population contains a variant that becomes adaptive after an environmental change, then the probability of a sweep to fixation is higher compared to a situation where an adaptive variant with the same level of benefit is invented … Meer weergeven The population is finite containing N individuals each possessing one variant of the cultural trait, either a or A. In each time step a new individual arises and adopts variant a or A, … Meer weergeven Next, we assume that the innovation of variant a occurred some time before the environmental change and unbiased transmission has caused it to reach frequency j/N, with \(j=1,\ldots ,N-1\) at \(T_0\). We … Meer weergeven We calculate the probability that the novel variant a will fix given that it arose after the environmental change at frequency 1/N.
