Philosopher Daniel Dennett, in his discussion of evolutionary philosophy, commented "During the last few years, when I have found myself in the company of distinguished biologists, evolutionary theorists, paleoanthropologists and other experts, I have often asked them to tell me, please, exactly why Elaine Morgan must be wrong about the aquatic theory. I haven’t yet had a reply worth mentioning, aside from those who admit, with a twinkle in their eyes, that they have also wondered the same thing." He challenged both Elaine Morgan and the scientific establishment in that "Both sides are indulging in adaptionist Just So stories". Along the same lines, historian Erika Lorraine Milam noted that independent of Morgan's work, certain standard explanations of human development in paleoanthropology have been roundly criticized for lacking evidence, while being based on sexist assumptions. Anatomy lecturer Bruce Charlton gave Morgan's book "Scars of Evolution" an enthusiastic review in the British Medical Journal in 1991, calling it "exceptionally well written" and "a good piece of science".
