Importante sint concluziile, care nu au fost demontate de creationisti:
The ev model can also be used to succinctly address two other creationist arguments. First, the recognizer gene and its binding sites co-evolve, so they become dependent on each other and destructive mutations in either immediately lead to elimination of the organism. This situation fits Behe’s definition of ‘irreducible complexity’ exactly ("a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning", page 39), yet the molecular evolution of this ‘Roman arch’ is straightforward and rapid, in direct contradiction to his thesis. Second, the probability of finding 16 sites averaging 4 bits each in random sequences is 2–4 x 16 5 x 10–20 yet the sites evolved from random sequences in only ~103 generations, at an average rate of ~1 bit per 11 generations. Because the mutation rate of HIV is only 10 times slower, it could evolve a 4 bit site in 100 generations, ~9 months, but it could be much faster because the enormous titer [1010 new virions/day/person] provides a larger pool for successful changes. Likewise, at this rate, roughly an entire human genome of ~4 x 109 bits (assuming an average of 1 bit/base, which is clearly an over*estimate) could evolve in a billion years, even without the advantages of large environmentally diverse world-wide populations, sexual recombination and interspecies genetic transfer. However, since this rate is unlikely to be maintained for eukaryotes, these factors are undoubtedly important in accounting for human evolution. So, contrary to probabilistic arguments by Spetner, the ev program also clearly demonstrates that biological information, measured in the strict Shannon sense, can rapidly appear in genetic control systems subjected to replication, mutation and selection.
Sincer, fizician fiind, imi trebuie ceva mai mult timp sa inteleg si eu ca lumea. Pot sa iti spun doar ca e esential modul in care iti propui sa definesti si masori informatia.
Am cautat si nu am gasit disponibila sursa. Fratii Nobel sint evolutionisti, de aceea eram curios din ce context este extras fragmentul care ii priveste. In general, argumentele creationistilor sint de acest tip.

Pai care sunt concluziile , cu cuvintele tale te rog, explica-mi si mie?
Macar te-ai uitat pe linkul ce ti l-am dat, in powerpoint? http://www.creationism.info.ro/blog7...nea-omului.htm numaru 2
Linkul citeaza si evolutionisti si apoi "ii combate".
