Fine tuning: a discussion for the rest of us mortals

Also consider that in the early solar system the conditions on venus, earth and mars were fairly similar, enough so that any significant change in the {power\effect} of the sun could easily mean that life would have formed on the second or fourth rock.Venus and Earth are very similar except for (1) run-away global warming on Venus has transformed it into a hot acidic atmosphere (2) run-away life on Earth has transformed it into an oxygenated atmosphere with secondary regulation mechanisms.In fact if all the CO₂ were 'liberated' the Earth could be another Venus. And there may well be some remnants of an archaic life form in the atmosphere of Venus from before the warming.⁽¹⁾We are also aware of the search for evidence of life on Mars and possibly on Titan as well.What this really means is that the range for a life viable planet to orbit a star like the sun is much greater than the Earth's orbit +/- 10%.

the order of the keys on the standard keyboard (qwerty) was to slow down the typing (yes spring-loaded key linkage systems) so that the commonly used keys wouldn't get jammed at the paper\ribbon.there are other systems that can be used that are much more efficient, but like a bad eye design this has persevered.

you can also get software to confvert your keyboardas far as the topic goes, this supports the position that there are a number of alternative solutions for any design problemthus having a different planet to start with would mean that the parameters of life would have to adjust to the different conditionswhat we see with the early development of life on earth is that early life adapted and changed the environment and that later life took the different parameters of the new environment into accountthis was the oxygen boom.enjoy.

more to the point ... why create one that is "fine tuned" instead of one that is stable?

Of course ... if there are mechanisms that hold a system within a fine-tuned envelope or that tend to return it to that envelope from any pertubation, but the anthropic concept is based on incredulity that it could be so arranged without outside help.And, of course, the answer is job security.
