And... why do you think his attempts have been utterly dismal?

It's really along the same line of logic that bacteria gaining antibiotic resistance is proof that nucleated cells spontaneously evolving from bacteria and multicellular organisms spontaneously evolving from single-celled life. Or that organisms can over time change their chromosome or gene numbers.

Here we show that activated pyrimidine ribonucleotides can be formed in a short sequence that bypasses free ribose and the nucleobases, and instead proceeds through arabinose amino-oxazoline and anhydronucleoside intermediates. The starting materials for the synthesis—cyanamide, cyanoacetylene, glycolaldehyde, glyceraldehyde and inorganic phosphate—are plausible prebiotic feedstock molecules12, 13, 14, 15, and the conditions of the synthesis are consistent with potential early-Earth geochemical models. Although inorganic phosphate is only incorporated into the nucleotides at a late stage of the sequence, its presence from the start is essential as it controls three reactions in the earlier stages by acting as a general acid/base catalyst, a nucleophilic catalyst, a pH buffer and a chemical buffer. For prebiotic reaction sequences, our results highlight the importance of working with mixed chemical systems in which reactants for a particular reaction step can also control other steps.

Our findings suggest that the prebiotic synthesis of activated pyrimidine nucleotides should be viewed as predisposed. This predisposition would have allowed the synthesis to operate on the early Earth under geochemical conditions suitable for the assembly sequence.

I agree.

Just funny to see ID'ers resist it... based on nothing.

Why do you think the E coli in his project has remained the same? The whole point is that it hasn't.

And, what is your argument that it hasn't?

Most recently (2012) his team has identified and sequenced the mutations leading to the new phenotype (consumption of citrate).

The hopes of this experiment was to have some laboratory proof of evolution. It hasn't produced that. Like I stated, if it had, it would have been trumpeted from the rooftops.

This is something I have been trying to get people to understand. We aren't close to being able to prove by experiments that man, and all life on this planet started from primordial ooze.

I hope this is someone beside Andrew Schlafly....

Who was able to confirm who was correct?

Ooze sounds icky... I prefer soup.

Because they are based in personal belief, and nobody is going to change minds. Believe in what you believe. Don't foist it on everybody else. If you're right, then you'll have a wonderfully unpopulated heaven to enjoy without all the heathens. If you're wrong, well, you'll be dead and it won't matter.
