Further evidence for Darwin's pangenesis.

Darwin's pangenesis, a developmental theory of heredity, has been largely thought to be wrong for more than a century. In this paper, further evidence for the inheritance of acquired characters and graft hybridization is provided. A striking similarity between mRNA and Darwin's so-called gemmule has been found by comparing their nature and function. I propose that once the term gemmule has been replaced by mRNA, Darwin's pangenesis will revive, indicating an important step in biology.
