Neuron-based heredity and human evolution
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. It is responsible for the evolutionary processes described by Darwin. By comparison, the nervous system is re...
متن کاملPhases of Evolution and Heredity
Next he discusses biometry as founded in Britain by Galton and as advanced by Karl Pearson, and he attributes great credit to the work of these men. To Semon, the author of Mnemism, Dr. Hart refers without immoderate criticism, but he suggests that the engram theory is as hypothetical as any of the suppositions of scholastic philosophy. He next proceeds to describe what is meant by mutation, bu...
متن کاملL. C. Dunn and Donald Charles on Quantitative Traits in the Mouse.
DUNN and Charles (1937, p. 14) opens with an understated assessment on the state of developmental genetics at the time: “The processes which lead to the formation of patterns during ontogeny in animals are at present very imperfectly understood.” This was the first in a series of five articles that proposed that understanding the highly variable coat patterns of the mouse could provide a model ...
متن کاملThe evolution of information storage and heredity.
Many important transitions in evolution are associated with novel ways of storing and transmitting information. The storage of information in DNA sequence, and its transmission through DNA replication, is a fundamental hereditary system in all extant organisms, but it is not the only way of storing and transmitting information, and has itself replaced, and evolved from, other systems. A system ...
متن کاملRadiation effects on human heredity.
In experimental organisms such as fruit flies and mice, increased frequencies in germ cell mutations have been detected following exposure to ionizing radiation. In contrast, there has been no clear evidence for radiation-induced germ cell mutations in humans that lead to birth defects, chromosome aberrations, Mendelian disorders, etc. This situation exists partly because no sensitive and pract...
