How do we want to explain the origins of behavior? And [Lehrman’s] critique seems to echo some of the concerns with evolutionary psychology. His approach can be gleaned from his example on the pecking behavior of chicks. Lorenz attributed this behavior to innate forces:The chicks are born with the tendency to peck; it might require just a bit of maturation. Lehrman points out that research by Kuo provides an explanation based on the embryonic development of the chick. The pecking behavior can actually be traced back to movements that developed while the chick was still unhatched. Hardly innate! The main point Lehrman makes: If we claim that something is innate, we stop the scientific investigation without fully understanding the origin of the behavior. This leaves out important – and fascinating – parts of the explanation because we think we’ve answered the question. As he puts it: “the statement “It is innate” adds nothing to an understanding of the developmental process involved”
