[QUOTE]Originally posted by DD'eDeN: [QB] Marine and terrestrial foods as a source of brain-selective nutrients for early modern humans in the southwestern Cape, South Africa K Kyriacou, DM Blackhurst, JE Parkington & AD Marais 2016 JHE 97:8696 doi 10.1016/j.jhevol.2016.04.009 <http://dx.doi.org/10.1016/j.jhevol.2016.04.009> <http://dx.doi.org/10.1016/j.jhevol.2016.04.009>Get> Many attempts have been made to define & reconstruct the most plausible ecological & dietary niche of the earliest members of the human species. While earlier models emphasise big-game hunting in terrestrial, largely savannah environments, more recent scenarios consider the role of marine & aquatic foods as a source of poly-unsaturated fatty acids (PUFA) & other brain-selective nutrients. Along the coast of S-Africa, there appears to be an association between the emergence of anatomically modern humans AMHs & accumulation of some of the earliest shell middens during the Middle Stone Age 200 - 40 ka. Fragmentary fossil remains classified as AMHs, along with marine food residues & numerous material cultural indicators of increased social & behavioural complexity have been recovered from coastal sites. In this paper, new information on the nutrient content of marine & terrestrial foods available to early modern humans in the SW-Cape is presented & compared with existing data on the nutritional value of some wild plant & animal foods in Africa. Results: Coastal foraging (particularly the collection of abundant & predictable marine molluscs) would have allowed early modern humans to exploit some of the richest & most accessible sources of protein, micro-nutrients & longer-chain omega-6 & omega-3 fatty acids. Reliable & accessible sources of omega-3 eicosapentaenoic & docosahexaenoic acid DHA are considerably more restricted in terrestrial foods [/QB][/QUOTE]
