My guess is it's more likely that they were going for the omega-3 fatty acids which are found at highest concentrations in organ meats, brain etc. Other hunters such as lions do the same thing. As well, skeletal muscle may be very lean and as such is avoided by hunter gatherers since the processing of so much protein to provide glycogen imposes a heavy load on the hunter gatherer's own liver. ----------------------------------------------------------------- The FAQ for Evolutionary Fitness is at http://www.evfit.com/faq.htm To unsubscribe from the list send an e-mail to [log in to unmask] with the words SIGNOFF EVOLUTIONARY-FITNESS in the _body_ of the e-mail.
