Lamarckism (or Lamarckian inheritance) is the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring (also known as heritability of acquired characteristics or soft inheritance).
Many of us have probably been taught that Lamarkian inheritance is anathema. Heresy. But why would that be the case? Is it for theoretical reasons or simply because of a lack of empirical evidence?
Let’s transition to a hypothetical RNA World.
Must it not have been the case that in the RNA world inheritance was strictly Lamarckian? How could it have been otherwise?
So at some point there must have been a transition from Lamarckian inheritance to Darwinian inheritance. Why would that be an advantage and why would vestiges of Lamarkian inheritance not still be evident?
