The African savanna ecosystem of the large mammals and primates was associated with a dramatic decline in relative brain capacity associated with little docosahexaenoic acid (DHA), which is required for brain structures and growth. The biochemistry implies that the expansion of the human brain required a plentiful source of preformed DHA. The richest source of DHA is the marine food chain, while the savanna environment offers very little of it. ConsequentlyHomo sapiens could not have evolved on…

TLDR
From a nutrient‐based perspective, it is suggested that consumption of LNA, available in a wider variety of sources within a number of terrestrial ecosystems, is sufficient for normal brain development and maintenance in modern humans and presumably the authors' ancestors.
Docosahexaenoic Acid in Neural Signaling Systems
TLDR
The well documented greater efficiency of preformed docosahexaenoic acid for brain incorporation during development would have conferred a distinct survival advantage over those without it.
Nutritional armor in evolution: docosahexaenoic acid as a determinant of neural, evolution and hominid brain development.
TLDR
It is suggested that the present paradigm of food production currently based on protein requirements, should change to serve the specific lipid needs of the brain to address the rise in mental ill-health.
The role of docosahexaenoic and the marine food web as determinants of evolution and hominid brain development: The challenge for human sustainability
TLDR
There is now incontrovertible support of this hypothesis from fossil evidence of human evolution taking advantage of the marine food web, as well as clear evidence from molecular biology that DHA is a determinant of neuronal migration, neurogenesis and the expression of several genes involved in brain growth and function.
The Fat from Frozen Mammals Reveals Sources of Essential Fatty Acids Suitable for Palaeolithic and Neolithic Humans
TLDR
The fat of single-stomached mammals often consumed by Palaeolithic/Neolithic hunters contained suitable amounts of n-3 and n-6 fatty acids, possibly in quantities sufficient to meet the today's recommended daily intake for good health.
Adaptive Evolution of the FADS Gene Cluster within Africa
TLDR
Evidence is shown that selection at FADS variants, which increase LC-PUFA synthesis from plant-based MC-PUFAs, played an important role in allowing African populations obligatorily tethered to marine sources for LC- PUFAs in isolated geographic regions, to rapidly expand throughout the African continent 60–80 kya.
A multidisciplinary reconstruction of Palaeolithic nutrition that holds promise for the prevention and treatment of diseases of civilisation
TLDR
The evidence for the long-reigning hypothesis of human evolution on the arid savanna is weighed against the hypothesis that man evolved in the proximity of water and the composition and merits of so-called 'Palaeolithic diets' are evaluated.
ARTÍCULOS DE ACTUALIZACIÓN Ácido docosahexaenoico (DHA), un ácido graso esencial a nivel cerebral Docosahexaenoic acid (DHA), an essential fatty acid at the brain
TLDR
The importance of DHA in the human brain is reviewed and the importance of this fatty acid in the development of the tissue and as neuroprotective agent is discussed, which includes a critical view about the use of this noble fatty acids in the population.

Rift Valley lake fish and shellfish provided brain-specific nutrition for early Homo
TLDR
P Paleoanthropological evidence clearly indicates that hominids evolved in East Africa, and that early Homo inhabited the Rift Valley lake shores, and 'brain-specific' nutrition had and still has significant potential to affect hominid brain evolution.
Are deficits of arachidonic and docosahexaenoic acids responsible for the neural and vascular complications of preterm babies?
TLDR
The conclusion drawn from this review is that present parenteral and enteral lipid nutrition for preterm babies is flawed and could be pathogenic.
Comparison of the fatty acid component in structural lipids from dolphins zebra and giraffe: possible evolutionary implications
TLDR
Data for two species of leaf-eating land mammals, the zebra, Equus burchelli Gray and giraffe, Giraffa camelopardalis L., indicate that tissue phosphoglycerides were dominated by n-6 fatty acids.

TLDR
A generalization appears to be valid for all tissues except the grey matter of the brain where, in a wide variety of different mammals, only three major PUFA occur: these are 20:406, 22:406 and 22:603 (Table I).

TLDR
The results suggest that the intake of DHA itself increases the DHA level of brain membranes more rapidly than intake of the precursors in animals fed a low n-3 fatty acid level diet.
