Evolution of Molecular Clocks
Michael Ruse, author of the book Defining Darwin, Essays of the History and Philosophy of Evolutionary Biology, concluded that “Indeed, the truth is that there is virtually nothing today in evolutionary studies that correspond exactly to the facts of the Origin.” Molecular clocks are one example.
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.”
