I read your comments in the Philadelphia Inquirer and think your take on pre-historic sexuality--and the more recent Spitzer mess--are fascinating. I can see that your book will be like one of Nelson DeMille's novels with intertwining plots and fascinating moments of recognition. Looking forward to reading Lust in Paradise.

The fact that we study the associated areas - rich with content - to identify an intersection that can let us know various things about the evolution may be a good research methodology. However, it carries its own backlogs in that; talking about evolution, we (those who do research on similar lines/areas) have succeeded mostly in bringing about new perspectives of how evolution could be understood. And then really, it is a reader's choice on what to accept and and what not to.

Yes! As you mentioned, these explanations may begin to answer the unanswered questions, but more often are successful in whetting the appetite for reading. To go beyond this, we may need to integrate the research efforts of the entire community, and present a comprehensive picture that does not leave a scope for guessing/choosing what is right and wrong.
