One more time: no, epigenetics is not Lamarckism | Biologie in de klas | Scoop.it
The standard model, so to speak, in evolutionary theory is known as the Modern Synthesis (MS), which was shaped during the 1920s, ‘30s and ‘40s by the founders of modern population genetics (Ronald Fisher, J.B.S. Haldane, and Sewall Wright) and by some other legendary names of modern biology (the geneticist Theodosius Dobzhansky, the naturalist Ernst…
