WebGenetic drift occurs when a population experiences random fluctuations in frequencies of genetic traits. The term “random” is key to an understanding of drift. If any heritable … WebDual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.Genes and culture continually interact in a feedback loop, changes in …
WebWe rarely found evidence for parallel changes in orthologous genes in the intraspecific comparisons, but in some cases we identified changes in members of the same gene family. Using among-species comparisons, we detected positive selection in 0.003-0.69% and 2.4-7.8% of the genes using site and stochastic branch-site models, respectively.
