dhw:Clearly then, nobody should argue that humans are an improvement over bacteria, let alone that H. sapiens "is a perfect solution to the problem". I did ask you before, what problem? Whatever it is, we'd better not say it involves improvement, even if some of us might think that solving a problem is better than not solving a problem.-The problem for me is the meaning of the existence of life with an evolutionary process involved. Where is it going? To make humans.
