This quote, " The study will permit the analysis of aspects of the technology, survival strategies and social organisation of the first farming communities which settled in the Iberian Peninsula."
Farming communities were much more advanced in all aspects of society than hunter/gatherer societies. The farming and the storing of food allowed them to develop governments, religions, laws, cooking, husbandry, farming and even rituals such as burying the dead. With free time or rather better use of their time, these communities could have developed bowyery or traded hunter societies for the bow. Much has been written about how much smaller in stature people were even just several hundred years ago; much less several thousand years ago. With smaller stature could come shorter bows and shorter draw lengths.. The fact that yew was used indicates IMO that trial and error at least in high quality bow woods had been achieved.
They "the archeological and academic" communities should be given a crash course in hunting, gathering, making, and building before they print articles with such gulfs of speculation.
Seriously...
