Researchers at Duke University in the United States have discovered a regulatory gene in the human brain that provides evidence of human evolution from lower mammals to modern humans.
They stated that this evolution is dependent on the highly dynamic changes of a gene known as prodynorphin, or PDYN. This gene plays a crucial role in regulating cognition, behavior, and memory in the human brain. The research team believes that, compared to lower mammals, humans possess a very specific variant of the PDYN gene, and it is this genetic variation that increases the number of PDYN genes in the brain.
According to the research team, this discovery partially answers some of the mysteries of evolution from lower animals to modern humans and paves the way for studying how natural selection influences the evolution of other genes in humans. The study was published in the December issue of the Public Library of Science.
