Why was Darwin’s (and technically Alfred Wallace’s) theories of mutability so revolutionary compared to Lamarck’s? What aspects of natural selection did Lamarck get right? What aspects did Lamarck get totally wrong? Remember to consider and give examples of mechanisms of inheritance on both the individual and populational level in Lamarck’s and Darwin’s evolutionary models, as well as the role environmental pressures playarrow_forwardName the scientist who had also come to similar conclusion as that of Darwin about natural selection as a mechanism of evolution.
