So DHA presents a MASSIVE problem for the Out of

sources in Africa, not very good sources at all on a

an environment were there was an ample supply of
DHA.
From where comes the data that DHA is so rare in
nature that one has to dive into ocean to find it? There
are zero sources in Africa. In reality there are no such
problem ... lot of edible things like eggs of birds and
termites, various seeds and nuts contain it plenty. That
was about older hominids. Newer ... h.sapiens has
mutations in the FADS2 gene, which encodes
Δ6-desaturase; a key enzyme for the synthesis of
DHA and sapienic acid so needs to consume it less.
But what about cannibalism?
I suppose if you want to argue that stereotypical
cannibal head hunter, you could spin a scenario
were the DHA they acquired in life, even if
insufficient, was augmented by consuming the brains
and hence the DHA accumulated by others.
A snowball effect?
Not sure how this isn't racist but saying they picked
up their DHA on a Southeast Asian beach is wildly
racist...
Not healthy. You have risk to gain the diseases and
parasites of victim. Mad Cow Disease (BSE) was
caused by body parts of cows being added to food
of cattle. IOW cannibalism is idiotic.
