Wow, the stupidity of this guy. To get 5 codons to mutate in
the "right order" it can mathematically take no more than 125
mutations. 1.5% of 3B is the same ratio even if there were more base pairs. But
that's also not how evolution works and mutations happen all the time, it's how
you age and develop cancer. You can make mutations to species in a lab for
crying out loud in a matter of hours.
One thing I learned a long time ago. You cannot fix stupid. So
let’s see how stupid this post is. You are arguing against Intelligent Design
and for blind evolution. But notice you cite intelligence as proof that
intelligence had nothing to do with it. “You can make mutations to species in a
lab for crying out loud in a matter of hours.” Notice you doubt not only the institution you
denounces but the very thing you denounces it with.
But let see if it takes only 125 mutations without any
guidance.
"To construct even one short protein molecule of 150 amino
acids by chance within the prebiotic soup there are several combinatorial
problems – probabilistic hurdles- to overcome. First, all amino acids must form
a peptide bond when joining with other amino acids in the protein chain. If the
amino acids do not link up with one another via a peptide bond, the resulting
molecule will not fold into a protein. In nature many other types of chemical
bonds are possible between amino acids. In fact, when amino acid mixtures are
allowed to react in a test tube, they form peptide and none peptide bonds with
roughly equal probability. Thus, with each amino acid addition, the probability
of it forming a peptide bond is roughly ½. Once four amino acids have become
linked, the likelihood that they are joined exclusively by peptide bonds is
roughly [1/2]^4. The probability of
building a chain of 150 amino acids in which all linkages are peptide linkages
is {1/2}^149, or 1 chance in 10^45.
Second in nature every amino acid found in proteins [ with
one exception] has a distinct mirror image of itself, there is one left handed
version, or L form, and one right handed version, or D form. These mirror image
forms are called optical isomers. Functioning proteins tolerate only left
handed amino acids, yet in abiotic amino acid production the right handed and
left handed isomers are produced with roughly equal frequency. Taking this into
account further compounds the improbability of attaining a biologically
functioning protein. The probability of attaining, at random only L amino acids
in a hypothetical peptide chain 150 amino acids long is [1/2]^150 or roughly 1
chance in 10^45. Starting from mixtures
of D and L form the probability of building a 150 amino acid chain at random in
which all bonds are peptide bonds and all amino acids are L form is, therefore,
roughly 1 chance in 10^90.
Amino acids link together when the amino group of one amino
acid bonds to the carboxyl group of another. Notice that water is the byproduct
of the reaction. [Condensation reaction].
Functional proteins have a third independent requirement,
the most important of all, their amino acids, like letters in a meaningful
sentence, must link up in functionally specified sequential arrangements. In
some cases, changing even one amino acid at a given site results in the loss of
protein function. Moreover, because a there are 20 biologically occurring amino
acids, the probability of getting a specific amino acid at a given site is
small 1/20 [actually the probability is even lower because in nature, there are
also may none protein forming amino acids.] On the assumption that each site is
a protein chain requires a particular amino acid, the probability of
attaining a particular protein 150 amino
acids long would be [1/20]^150 or roughly 1 chance 10^195. 1chance in 10^195.
Taking this into account only causes the improbability of
generating the necessary proteins by chance or the genetic information to
produce them, to balloon beyond comprehension. In 1983 distinguished British
cosmologist Sr. Fred Hoyle calculated the odds of producing the proteins
necessary to service a simple one celled organism by chance at 1 in 10^40K.
