This is the book I was telling you about: http://www.amazon.com/exec/obidos/tg/detail/-/0385498411/qid=1071274625//ref=sr_8_xs_ap_i0_xgl14/103-7308187-9141430?v=glance&s=books&n=507846 I had used the wrong terminology. I had meant that she challenged "evolutionary psychologists" not "evolutionary biologists".
