I don't doubt that. My kids seldom had colds before they started
attending school. (Note: not "never", but "seldom".) But it doesn't
really say anything about whether or not colds were a problem in
paleolithic times. Sure, they might not have spread as quickly, but once
one member of a group (family, pack, tribe, or whatever) became infected
with something, it would have spread among that group. I have no doubt
that infections spread more quickly in a dense population, but it does not
follow that dense population *causes* the infection.
And even if it did, it still wouldn't show whether or not colds were a
problem for paleolitic man. My point was that we have no idea whether or
not paleo man had a cold once in a lifetime or six times a year. It's not
like having a cold would show up in your bones a million years later.
