Wow, OK. This article is awful and shouldn't be propagated. First of all, nobody serious is promoting any Lamarckian theory of evolution. The claim that mutation rates are too slow to explain phenotypes is completely bizarre. Nothing about modern measurements of mutation rate undercut Darwinianism or promote Lamarck. This is utter nonsense.
If the framing was intended to present a molecular mechanism for inheritance via epigentics that is distict from classical genetics, then nothing about Lamarckianism is relevant whatsoever. We simply have expanded our understanding of genetics and short-term heritability to include epigenetic modifications, but modern genetics is not somehow in conflict with Darwin. Epigenetic changes occur during development and may be affected by externalities within an individual in a manner that biases the propagation of genotypes. But epigenetics is in no way teleological in the manner that Lamarck proposed.
