Understanding of Lamarck was and are very different, but currently the view clarifies where Darwinian and Lamarckian mechanisms are not conflicting. Lamarckian mechanisms exist and offer evolutionary changes “from instructions”, usually much more accurate adaptively than if they were completely random, but this instruction was found earlier by Darwinian natural selection. Lamarckian mechanisms alone do not explain the obtained purposefulness. They gain this ability only with the mechanism of their occurrence, which is Darwinian. In the case of multicellular usually their effect requires the strengthening of inherited through genetic assimilation, but in range of memes and culture "realized needs" seems to be the main mechanism.
