In the mid-nineteenth century, the idea of molecular clocks was not even remotely considered, not to mention cellular biology or DNA. The scientific revolution had yet to reach into the realm of molecular biology. Case-in-point, Darwin thought “gemmules” learned by parents were passed on to the next generation through a process of “blending inheritance.”
