Here's the new thread for posting quotes, with the usual rules:
Please post all quotes separately, so that they can be voted up/down separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
Do not quote yourself.
Do not quote comments/posts on LW/OB.
No more than 5 quotes per person per monthly thread, please.
I understand why group selection is problematic: Individual selection trumps it.
However, when group and individual selective pressure coincide, the mutation could survive to the point where it exists in a group at which point the group will have better fitness because of the group selective pressure.
