Dr. Lamarck I Presume

Notice also that nobody is even using the word Lamarckism, though that is precisely the term for instances where environmental changes get translated into heritable characteristics. The standard example is the long neck of the giraffe, gained over generations of stretching to reach high leaves. I think now of studies suggesting  trauma affects the genes of offspring, among other headlines. For most of the last century Larmarckism has been an example of out-moded thought. It had to be--- since ordinary thought is binary. This means Darwinism is defined by what it is not--- and it is not Lamarckism. This was the natural conclusion with the explanatory success of Darwin's idea. But step back--- why couldn't both explanations be correct. Why can't evolution have two methods of advance. What a good question.
