Are Men Responsible for Human Evolution?

Are men responsible for the evolution of the human species?

Time magazine reported in a cover story, "How We Became Human" that a gene-by-gene comparison showed that "the most striking divergence between them occurs, intriguingly, in the Y chromosome, present only in males."

William Tucker explores further in Bulletin -- Men Invented Humanity.

The role of females hasn't changed much - mothers nurse and care for their children much as chimps do. What's changed, he says,  is the role of males,    From male brotherhood, they learned to work together co-operatively.  Along with monogamy and the "invention of fatherhood" these have been the primary pathways to human evolution.
