"text": "In retrospect, there were three main defects of Darwin's \"pangenesis\" theory of inheritance: (1) the presumption that there was a gemmule corresponding to every trait and specific to one and only one trait; (2) the idea that copies of all gemmules are transmitted to the next generation; and (3) the idea that somatic changes occurring during the lifetime of an individual could locally alter gemmules proceeding from the affected organ and then be passed to subsequent generations via gemmule replicates contained in the gametes.",
