A)...probably none. Sooooooooooo what's your point?
So nice of you to invent an answer for us. Fortunately it is
incorrect. You claim that there are no favourable mutations.
To falsify that all I have to do is point to one favourable human
mutation. I am not a geneticist, but I can point to several off the top
of my head.
1.Fair skin – an adaptation to northern latitudes.
2.Laplanders possess a mutation that allows their core body temperature
to drop without catastrophic hypothermia.
3.The recently discovered 'plague immunity gene' of European origin.
4.Adult lactose tolerance, European.
5.Adult lactose tolerance, African (different mutation, same effect)
6.Adult lactose tolerance (third mutation, same effect)
7.APO1 Milano, which confers immunity to bad effects of dietary
cholesterol Of course there are a myriad of others,
but that's enough that your assertion goes down in flames.
Oh, and if there just so happens to be two...what are the odds of them
effecting the same trait?
Oh, good! Let's do the math! Humans have about 3 x 10^9 base
pairs in their genome, encoding 2 – 2.5 x 10^4 proteins.
Protein coding represents about 1.5 x 10^-2 of the genome, with maybe .8
of it given over to regulatory code. Thus the average protein is coded
for by about 4.5 x 10^7 / 2.5 x 10^4 = 1800 codons. Now, more than one
protein is involved in any part of the body. Let's call it 10, thus coded
for by 18000 codons, on the average. In addition, gene expression is regulated
by roughly 2.7 x 10^9 codons. Let's assume that a similar proportion of
regulatory DNA is involved as protein DNA. Let us also assume that only
one regulatory area affects each protein... so we are looking at 1/2500
of the regulatory code... about 2.7 x 10^9 / 2.5 x 10^3 or roughly 10^6
codons. Thus the total codons involved in one of your ill-defined traits
is about 10^6 + 1.8 x 10^3, which is 10^6 codons. Now, each codon in the
human genome is mutated every 20 years, so each 'trait' (whatever that
is) is mutated 10^6 times every 20 years. We also know that the fixation rate
of neutral mutations is about 10^-5, so about 10 changes to any 'trait'
(sic) will be fixed each generation. Once that happens sexual
reproduction and continuing mutation both guarantee that the same 'trait'
(sic) will be the subject of multiple neutral mutations. Of course, any beneficial
mutations will fix more often, and spread more rapidly and thus add up
more rapidly. PS... on the rapid spread of beneficial mutations - note that
adult lactose tolerance is found in .98 of people in some of the Northern
European populations in only 10,000 years. The proportion is about .75
among the Fulani people in the Sahel, .... since domesticated cattle
reached this area just a couple of millennia ago.

misconceptions that genes are created de novo and that the odds of
randomly constructing an entire functioning gene from scratch are in some
way relevant to a debate over evolution. They aren’t, and they aren’t.
Evolution doesn’t work by building new genes for new proteins very often.
It works by sequentially modifying existing genes and proteins. It’s not
the odds of getting a specific sequence in isolation; it’s the odds of
getting a sequence that works. And working means interacting and
expression with the all other sequences that are present.

You YEC guys keep dodging that one.(And yes, we know it isn't a

It's one of those basic math concepts that I just assumed (erroneously,

The only real question is how the YEC team is going to try to wriggle out
of their obvious problem --- a mutation that adds an entire new
chromosome to a person's genome can not be doing anything except adding
The YEC claim is that mutations don't add information. The mutation for
Down's syndrome adds a complete or partial chromosome.Therefore, the YEC
claim is provably wrong: mutations can --- and obviously do --- add
This is where the YEC team either ponies up evidence showing Down's
syndrome isn't accompanied by a full or partial extra 21st chromosome or
the YEC team admits that their claim about mutations not adding
information is complete crap.
If the YEC team is unable to grasp the concept of 2 > 1, then obviously
the YEC team is unable to grasp any part of the more complicated aspects
of any mainstream math or science, like addition.
So, 57 --- yes or no --- does the mutation responsible for Down's
syndrome, which adds a complete or partial 21st chromosome, add genetic
Yes or no, dude?
Original quote here:
and of course here's a whole thread dedicated to the subject:
And here's the mutation rate...
1. Humans each have on the average about 129 mutations (quoted figures
from various sources lie between about 125 and 135 mutations per
2. A more general metric, applicable from everything from E coli to
humans is that the overall error rate during DNA replication is 10^-10
nucleotides per replication. In order to get the mutations per
generation, look up the size of the organisms genome, and apply the post
repair mutation factor of 10^-10.
Thus for E coli, the estimate goes like this:
"Our model bacterium is Esherichia coli the common, and mostly benign,
intestinal bacterium. The entire genome was sequenced in 1997 (Blattner
et al., 1997) and its size is 4,200,000 base pairs (4.2 × 106 bp). Every
time a bacterium divides this amount of DNA has to be replicated; that’s
8,400,000 nucleotides (8.4 × 106).
* * *
This means one mutation, on average, every 1200 replications (8.4 × 106 ×
1200 is about ten billion). This may not seem like much even if the
average generation time of E. coli is 24 hours. It would seem to take
four months for each mutation. But bacteria divide exponentially so the
actual rate of mutation in a growing culture is much faster. Each cell
produces two daughter cells so that after two generations there are four
cells and after three generations there are eight cells. It takes only
eleven generations to get 2048 cells (211 = 2048). At that point you
have 2048 cells dividing and the amount of DNA that is replication in
the entire population is enough to ensure at least one error every
"I based my estimate of mutation rate on what we know about the
properties of the replisome and repair enzymes. Independent measures of
mutation rates in bacteria are consistent with this estimate. For
example, the measured value for E. coli is 5.4 × 10-10 per nucleotide per
replication (Drake et al., 1998). Many of these mutations are expected
to be neutral. The rate of fixation of neutral mutations is equal to the
mutation rate so by measuring the accumulation of neutral mutations in
various lineages of bacteria you can estimate the mutation rate provided
you know the time of divergence and the generation time. (Ochman et al.,
1999) have estimated that the mutation rate in bacteria is close to
10-10 assuming that bacteria divide infrequently.
The mutation rate in eukaryotes should be about the same since the
properties of the DNA replication machinery are similar to those in
eukaryotes. Measured values of mutation rates in yeast, Caenorhabditis
elegans, Drosophila melanogaster, mouse and humans are all close to 10^-10
(Drake et al., 1998).
The haploid human genome is about 3 × 109 base pairs in size. Every time
this genome is replicated about 0.3 mutations, on average, will be
passed on to one of the daughter cells. We are interested in knowing how
many mutations are passed on to the fertilized egg (zygote) from its
parents. In order to calculate this number we need to know how many DNA
replications there are between the time that one parental zygote was
formed and the time that the egg or sperm cell that unite to form the
progeny zygote are produced.
In the case of females, this number is about 30, which means that each
female egg is the product of 30 cell divisions from the time the zygote
was formed (Vogel and Rathenberg, 1975). Human females have about 500
eggs. In males, the number of cell divisions leading to mature sperm in a
30 year old male is about 400 (Vogel and Motulsky, 1997). This means
that about 9 mutations (0.3 × 30) accumulate in the egg and about 120
mutations (0.3 × 400) accumulate in a sperm cell. Thus, each newly
formed human zygote has approximately 129 new spontaneous mutations."

One interesting thing in this case was that since there are a small
number of nucleotides, the researchers can examine the changes that occur
over time at a minute level. The bottom line is that after a number of
generations, 3 mutations occur that increase the survivability of the
RNA. Further, the scientists know exactly which 3 nucleotides changed
(say for A to U) and the sequence of the change.
In other words, this is a case where the reserachers could literally
