As just one example, the “pangenes” invented by Hugo de Vries were hereditary units which were similar to chemical molecules except that they could not be isolated and could not be analyzed experimentally.

  38. Some commentators on the Ancestral Law were surprised by it, not because Galton had arrived at a numerical value for the contribution of each ancestor, but because ancestors beyond the parents were implicated in the first place. See, for example, J. A. Thomson, Heredity (London, 1908), pp. 321–323.

  39. This is said despite the fact that the Mendelians and the Galtonians did battle with each other during the first decade of genetics. As with many warring married couples, they had much in common despite their differences. In this connection it is interesting that William Bateson criticized the concept of “reversion” several years before the rediscovery of Mende's work and several years after the publication of Galton's. “It would probably help the science of Biology,” Bateson wrote, “if the word ‘Reversion’ and the ideas which it denotes were wholly dropped” (Materials for the Study of Variation [London, 1894], p. 78).
