Ancient Near Eastern (and Egyptian) Angular Bows - links and pictures

Found the following information while experimenting with wood only angular self bows : 

(from Mc Leod's "Composite bows from the tomb of Tut.ankam.um", see below)

• links to photographs, with some details, 
• links (and a few comments) to some papers of interest.

Links to photographs and videos of Assyrian reliefs from the British Museum 

Click on the B.M. numbers to get to the B.M. web site and to the original photographs. The pictures shown here are only small details of the originals. Once on the B.M. site, browse the page to see the more pictures offered for the same relief.

Corrections 2021 : the british museum's web site seems to work differently now... so, copy the number into the search field in https://www.britishmuseum.org/collection

Digesting milk : is it in the genes or in the gut bacteria ?

First time I finally read that gut bacteria (and not genetic traits) could be what helps humans digest milk.

OK, I'm wildly interpreting this article : http://www.upenn.edu/pennnews/news/penn-team-links-africans-ability-digest-milk-spread-cattle-raising, about a study led by University of Pennsylvania researchers on genes and lactase persistence in African populations. It ends with "Another possibility is that commensal bacteria in the gut could offer humans a helping hand in digesting milk."

My guess
