Okay. Hardly matters to the point I'm making.
As you stated, Hamilton was intent on denying
the existence and/or importance of selection
at any other leve than organism-level.

It would seem, if we read your words further
down on this same post, that he was unsuccessful
in this fight. In fact, if what you're saying
is accurate, he switched sided to accept levels
of selection other than just the organism level.
Isn't this essentially to concede that his
organism level version of Hamilton's rule (the
earlier version) is wrong?

This makes no sense at all. If they both look
at the same phenomena and give two different
results then we know that at least one of them
must be wrong. Right?

All three of which are invalid.

Yep.

Nonsense. You haven't even broached the
subject of why we should employ IBD to calculate
relatedness.

You need to keep your nose to the grindstone,
boy, and don't go off on flights of fancy.
I have no problem at all conceding that you
understand Hamilton's intentions better than
I do. It hardly matters. You have two gigantic
obstacles standing between yourself and success.
You still haven't provided a rationale for
employing IBD to determine relatedness. (You
will never get beyond this obstacle. Employing
IBD to determing relatedness is pure nonsense.
There is no solution to this problem.)

Also, you still haven't described how we
calculate C (cost for the altruist) and B
(benefit for the reciepient of the altruistic
activity). Allow me to help you on this. We
will not (should not) have any dispute about
what units are employed. Obviously the units
involve units of fitness and obviously these
are difficult or impossible to actually
calculate. So I'm quite happy to leave the
actual units of fitness as theoretical. This
should save us a lot of unnecessary argument.
But here's the problem. Hamilton assumed that
individual organisms had discrete fitness
measurements. IOW, Hamilton was completely
blind to the possibility that any two organism
might have overlapping fitnesses.

What do you think?
