It is widely recognized that human evolution has been driven by two systems of heredity: one DNA-based and the other based on the transmission of behaviorally acquired information via nervous system functions.The genetic system is ancient, going back to the appearance of life on Earth.A fundamental process in rewiring brain circuitry is through increased neural activity (use) strengthening and increasing the number of synaptic connections.Decreased activity in circuitry (disuse) leads to loss of synapses.The human genome has been aggressively sequenced along with that of other species.The science of genetics has matured to serve as a cornerstone of modern agriculture, biology, biotechnology and medicine.Here neuron-based heredity is analyzed as a principal component of hominin evolution leading to the current species with a highly developed capability for mind-to-mind exchange of information.

But because of the difficulty in linking behavioral observations to neural processes, the nature of non-genetic contributions to bipartite human evolution has remained controversial (Boyd and Richerson, 2000; Kuper, 2000).The simple millimeter-long nematode worm , which lives in the soil and feeds on bacteria, has 19,735 protein-coding genes, approximately the same number of as humans (Hillier et al., 2005).With a life span under 4 weeks, the nervous system of an adult male consists of 302 neurons (White et al., 1986).The heritage of acquired information provides the cornerstone for human culture.As the cellular and molecular mechanisms of the two systems of heredity are very different, genetics and neurobiology have developed as separate scientific disciplines with often only modest overlap.
