More reasons why evolution is impossible

I asked for feedback on my conclusions on Evolution from some of my chemistry friends, and received this from someone with a PhD in Physical Chemistry:

“You could strenghten your argument by mentioning that not only do you have to get the right AA sequence but also the right DNA sequence to code for the AA first which then gets translated and post modified which would take much longer than 1 nanosecond as Levinthal suggested. On top of that you have not just one but hundreds of proteins in a single organism. Point: your estimate is quite generous to the evolutionists since in reality it would take much longer.
Another weakness is that your calculations assume that we are only trying to make one protein at a time instead of billions or trillions simultaneously and then selecting the one that works. This is how I would envision it happening from the Darwinian point of view. This is how we do techniques like phage display in the laboratory. Right now I work with a peptide that was one of 24 that were found to bind to the surface of silver out of a library of 10^11 – 10^14 peptides. They were all tried simultaneously and then selected. Of course an individual microorganism is not capable of simultaneously producing so many peptides, but a several microorganism could. Question is how did the first microorganism develop the right machinery so randomly to begin with? Are all these proteins just floating around somewhere? I don’t observe that anywhere now, why would we assume so in the primordial soup? Miller-Urey is a nice thought but we know there was no H2 in the atmosphere.”

The conclusion; my arguments could have been much stronger.  I decided not to get into some of these topics, because I didn’t want to overwhelm anyone with how insane the process is.  But, it is much, much more complicated than I described.

Who ‘believes’ in Evolution? – Evolution (Part 2)

Because the theory of evolution is just a theory, no one knows what it may have been like when the first cells were developed.  One theory is that amino acids were formed, they formed into proteins, which eventually built a one celled organism.  Another theory is that self-replicating RNA was the first thing created, and it continued dividing and eventually created a one-celled organism.  The one celled organisms became multi-celled organisms, and continued developing.  I’m just trying to explain the complexity of the very first step.  In order for a protein to build a cell wall, it needs to be a protein that can build a cell wall.  There also need to be many proteins.  Proteins that build the lipids the cell wall is made of.  Proteins that transport the lipids.  Proteins that bind the lipids.  Proteins are needed to build other proteins.  And to be any kind of efficient, there should be dozens, if not hundreds, of copies of each of these proteins.  One of each required could theoretically build a cell, but it would take a long, long time.  In reality, the proteins would probably denature (die) before they got anywhere near finishing an entire cell wall.  Not to mention, once you have a cell wall, you need a system to keep the cell alive.  I don’t know exactly what the theory is on how it started, but either the couple of dozen specific proteins needed to build a cell wall all happened to be in the same puddle at the same time, or there was a DNA strand that happened to give the directions for building cell walls with a protein that happened to be able to read DNA, and then proteins that could build the proteins the DNA coded for.  If neither of these things happened, cells could not have naturally evolved.  Remember that my example was one protein, not a thousand different kinds that would have been needed to work together to build a simple cell.

What are the odds? – Evolution (Part 1)

I majored in Biochemistry and minored in Physics.  I studied Biology at a molecular level, which is something most Biologists don’t do, and happens to be the level at which evolution is theorized to take place.  There are two theories pertaining to evolution; naturalistic evolution and theistic evolution.  When I use the word ‘evolution’ I’m referring to naturalistic evolution.  This form of evolution assumes that all progression, from no living things at all, to a collection of amino acids, to single celled organisms, all the way to humans, happened completely naturally, by chance, without any outside interference.  This is the form of evolution proposed by Darwin.  It is the theory of evolution taught in schools and will typically be the form of evolution referred to when you hear it discussed.
