WebbHe also developed a theory for the mechanism by which changes in the soma might be transmitted to the germline cells, sperm and eggs. He supposed that tiny particles, called gemmules, can move through the body, presumably via the body fluids.

WebbHugo de Vries's theory of Intacellulare Pangenesis [ de Vries, 1889 ], developed in the last decades of the nineteenth century, which was both reductionist and preformationist, was intended to replace, or at least update Darwin's hypothesis of evolution by continuous variation.

WebbPangenesis was Darwin's attempt to provide such a mechanism of inheritance. The idea was that each part of the parent's body emitted tiny particles called gemmules, which migrated through the body to contribute to that parent's gametes, their eggs or sperms.
