Charles Darwin didn’t know about DNA. He hadn’t read any of the research done by Gregor Mendel who showed us in pea plants how inherited traits are passed from generation to generation. But if he were to have been given a chance to see these scientific discoveries, it would have reinforced the conclusions he drew from observing the finches of the Galapagos and other creatures throughout the voyage of the Beagle. So, what this article describes is thoroughly consistent with Darwin’s description of how species adapt to the environments in which they live.
