Pangenesis was Charles Darwin 's hypothetical mechanism for heredity, in which he proposed that each part of the body continually emitted its own type of small organic particles called gemmules that aggregated in the gonads, contributing heritable information to the gametes. [1]

2014年7月20日 · In 1868 in England, Charles Darwin proposed his pangenesis theory to describe the units of inheritance between parents and offspring and the processes by which those units control development in offspring.

…devised the hypothesis known as pangenesis. He postulated that all organs of the body of a parent gave off invisible “seeds,” which were like miniaturized building components and were transmitted during sexual intercourse, reassembling themselves in …

There is now a solid foundation for the concept of Pangenesis as a molecular, cellular and physiological explanation for the inheritance of environmentally-induced acquired characters in higher animals (with a Weismann Barrier) and plants (with no traditional Weismann Barrier), see Fig. 2 and legend, and the review by Noble (2019).

In 1868 Charles Darwin proposed Pangenesis, a developmental theory of heredity. He suggested that all cells in an organism are capable of shedding minute particles he called gemmules, which are able to circulate throughout the body and finally congregate in the gonads.

This paper explores Charles Darwin's hypothesis of pangenesis through a popular and professional reception history. First published in The Variation of Animals and Plants under Domestication (1868), pangenesis stated that inheritance can be explained by sub-cellular "gemmules" which aggregated in th …

It is in the second great book that Darwin took a broad survey of the whole range of variation and heredity, and developed his Pangenesis, an expanded cell theory and a unified genetical theory that would strengthen his theory of evolution and explains the numerous phenomena of life.

Pangenesis's borderline position between empirical natural history and ideal speculative hypothesis made it as pertinent to cellular mech- anists as metaphysicians.
