Re: coevolution of the genetic code

PS: The genetic code represented in a circular fashion following 2-1-3 rules and applying the AGCU motif has been published in the Journal of Theoretical Biology. (Please quote: Pohlmeyer R. The genetic code revisited. J Theor Biol. 2008 Aug 7;253(3):623-4. Epub 2008 May 1.)

ignore the id

Sorry, I didn't mean to turn this into another debate about ID. I just thought that this simplification of the genetic code could be interpreted this way, and that I should make my position clear. It seemed to me that the postulate of irreducible complexity was something that I should address as a b...

reducible complexity

By the way, this perspective lets the code appear so simple/ logical that it is well-conceivable that the code evolved on its own without the interference from an intelligent designer. Sorry creationists, but I think that unless you see God and the universe as one or you place the act of creation be...

charles brough's post

I just wanted to clarify that the quote in Charles Brough's post was wrongly attributed to myself. I personally am not sure where I stand on Social Darwinism. On the one hand, human behaviour is clearly governed by natural processes that can be explained scientifically and which can be interpreted f...

nucleic acid + amino acid -> genetic code

Hi Darby, Gosh, this is getting a bit technical. First of all, I am really thankful for any kind of criticism, be it positive or negative, the important thing here is dialogue where trying to understand you makes me better in arguing my case. I'm an immunologist by training so I'm a bit rusty on Dar...

Reply to Darby

Dear Darby, I'm trying to take your criticism on board but I'm not sure whether or not we are talking about the same thing here. I'm just trying to put my observation that the code seems quite logical into a larger context and am quoting Jeffrey Wong's theory of coevolution of the genetic code (e.g....

More stuff

If you want some more information about this topic, I put some results down on http://www.rna-game.org and http://livescience.blogspot.com. But I really enjoy the contributions on this topic, so please feel free to post more questions here.

Evolution or creation? Is this what it boils down to? Are they not nearly synonymous? I think that we should all respect each other's points of views. If someone believes in God, good on him/ her. I have always admired people who had this personal relationship with their God, unfortunately I have no...

I guess this question brings us to examine closer how we define life itself. We are talking about processes that occurred more than a billion of years ago, and we have little evidence of how and in what order these events took place. Robert Shapiro recently wrote a very interesting article on the me...

Oh by the way, there are two more rare amino acids selenocysteine (codon: UGA) and pyrrolysine (codon: UAG) that fit ever-so-neatly into the scheme. It's massive! But it takes a while to get used to it.

Some explaining...

Sorry to leave you confused for so long, but I will try to do my best to explain what the wheel is meant to show. An old dogma in biology states DNA makes RNA makes protein. Previous depictions of the code have focussed on the DNA/ RNA level, with a rigid order of bases. The result of that approach ...

altruism - shmaltruism

My main problem with concepts such as altruism and egoism is that these are merely human concepts. Nature selects strategies that work, that's all. Now, if the environment is limited in resources it seems that competition between individuals for energy and nutrients ensures the individual's own surv...
