I attempted to make the point previously that such behavior should not be
assumed to be indicative of what's optimum for human health. Another way of
putting it: what man did/does, is not necessarily what's optimum for man to do.

Flax seeds are the richest source of omega-3 fats that I know of, and
they're a plant food. Other plant sources that contain substantial amounts
of omega-3's include hemp seeds, pumpkin seeds, and walnuts. Fresh green
plant foods (leafy greens, grasses, etc.) also contain omega-3's, albeit in
smaller amounts in comparison to the nuts/seeds, but which become of more
substantial significance when greens are eaten in sizable quantity.

Mono-unsaturated fat is abundant in nuts and seeds. Avocados are
particularly rich in it as well.

Omega-3's and omega-9's (mono-unsaturated) are easily obtainable from the
above-mentioned plant sources. Whatever nutrients that are of value in
animal-source food are likely something other than those particular nutrients.
