okay, for hardcore, i was seeing the rolled-eye smilie as a sarcastic jab to puntuate was he said, and i was just taking it to a sarcastic extreme.
Hey, Lib, i think you need to set up a website, so whenever someone asks you the same questions again and again, you can just direct them there, instead of repeatedly saying the same thing, getting annoyed, then everyone end up thinking you’re a jerk (i know i did at first before i realized why you got snippy sometimes). Then you can tell who hasn’t taken the time to read you site and deem them unworthy of acknowledgment.
for jab, the random part of evolution is the mutations, coupled with what is happening in the environment at the time. white hair may be a wonderful advantage in the polar region or the desert, but if you live in a heavily forested area, you tend to stick out more and have a better chance of being eaten. most mutations are bad for whatever gets them, that is part of evolution also, the part you don’t see walking around the forest.
