| Scoobes said: Smidlee, the comparison doesn't work. They are talking about highly conserved and identical sequences of RNA. The reason why they say they're primordial is because they are quite literally identical in all walks of life. When you look at ATP Synthases, the DNA and amino acid sequences vary wildly and the mechanisms of action vary wildly from organism to organism. Unsuprisingly, the more complex the life form (and hence a larger energy output required), the more complex the ATP Synthase enzyme. In fact, it is just further evidence of evolution in action, as they have similar functions but have evolved to meet the energy needs of the host organism. |
This is where we differ, of course ATP Synthases has to meet the special needs of different life form yet there are similarities as well. (just like a lawn mower engine has similiarities with a F1 car engine) This is not "evolution" in action, this is a statement of faith. (Both similarities and differences are so call evidence of evolution.) Thus "evolution" is just a label to slap on anything scientist learn about life.
As far as blind faith , even scientist can be decieved just any man can. (some clearly believe in some kind of god-subsitute) All throughout history it's been about nature gods (creators) vs spiritual ones.
P.S Note the article state these RNA appears ALMOST everywhere in the tree of life (some have stated in the past this so called tree only exist in the human mind... just like RNA world) thus there must be exceptions.
This reasoning goes like this: Since it near impossible for these RNA appear once by chance then it''s even more impossible to pop up twice thus common RNA has to mean common ancestory.
