And when you open the valves on an irrigation system, doesn't the water tend to follow a predefined course?
Ah but evolution is not predetermined, had hominids not walked upright chances are we would not be talking on the computer. Had they stayed hanging under tree we would syill be more like gibbons.
Had a comet not struck the earth about the time that antartica split from india then the course of evolution would be very different. A gracile dinosaur might have arisen or the earth might be waiting for a different species to evolve intelligence, it is a contingent property not an unavaoidable one.
I understand the part that the potential for a uniform or consistant method of molecular bonding is what leads to rna/dan, and I agree, if chemical bound chaoticaly then the process would not work.
But the fact that it did arise is still contingent upon the path taken, a different turn in the course and you get different dna/rna with different properties and potentialy a whole different expression of potential lifeforms.
So I see no predisposition there.
When people do stupid things people suffer. Is that so hard to understand?
