Hello Todd,
my impression from recent posts was, that there is a theory that
humans need so much of these w-3-fats because our brain is so big
(3 times bigger as apes').
And that eating brains was necessary (or making possible)
that our brains could *grow* so big.

I think this only counts in the build up phase of the brain, until
these 2 or 3 pounds of fat are complete.

Something else is the daily *consumption* of the bigger brain.
Is somebody supposing a bigger w-3 fat consumption of
 a bigger brain?

We do know that a bigger brain has a bigger *vitamin-b1* consumption.
(Did anybody read what I worte about it in my first post at this thread?
 It was below a citation block)

It made me smile to read about the squirrels' brain in annother post.

Wouldn't you agree that evolving humans did
get their APA/EPA supply from plants  *at least* up to
2 million years back from today?
(hominds are counted from 4 million years back from today).

The later hominids seem to have had both possibilities:
w3-fats from plants (purslane... and other "weed"
:-) )
or from mammal brains.
Since many humans of today never eat brain or fish, and stay
(reasonable) healthy, it appears as if we were not dependent on
brain or fish as a supply.
