<div>Right, </div> <div>what Spike mentioned is in the line of what I meant (expressed in more eloquent words)</div> <div>and please if anybody can show me how to calculate the probability of survival of a black bear in the artic versus a white one, let me know....I will like to learn to do similar calculations...</div> <div>Also why orange cats are orange? Is that a good coat to hunt in candy-land?</div> <div>It is silly to try to explain everything (in particular complex human behavior, motivations and desires) with a simplicistic and reductionistic chain of reasoning as: this random event happened that selected this particular trait because of a higher probability of survival for individuals with this trait and so on... the elementary school description of the evolutionary process I understand well, lol, but sorry it seems very silly to use it to explain why I watch this tv show instead of that other one...</div> <div>And yes while the
instances of adaptation are examples of the evolutionary process the overall process that we call evolution is the entire history of life on the planet and of this there is just one example (even if we can speculate and imagine how evolution could unfold on other planets, such exercise is more fantasy than real science until we can get data to compare with our speculations).<BR><BR><B><I>spike <spike66@att.net></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">> bounces@lists.extropy.org] On Behalf Of scerir<BR>> Subject: Re: [ExI] Anti-transhumanist crap on Kuro5hin and related.<BR>> <BR>> Giovanni ha scritto:<BR>> I think it is kind of silly to try to "explain"<BR>> evolution in terms of "chance".
