Different subject - Don't know where to ask
can the ocean life alone produce enough oxygen to sustain an atmosphere with ozone if there was no life on land?

Re: Peer review / topic drift
How interesting that Koonin wrote that creationists will misunderstand what he is actually stating in his findings. I read his papers and most of them do support creationist thought process. Since he already knew it when he wrote it perhaps he should have presented it using different words to explain it. I see this as manipulative on his part and it was deliberate. He wanted his paper published and he knew that writing it the way he did would get the public's attention. Presentation is better than content which translates to I will just bullshit a great story because after all nobody really understands or cares about the content.
Information via the web is indicating many scientists do not share the same opinion or produce the same results on repeated studies. Often the journals indicate that the models used are not accurate because the data is no longer true or is incomplete yet to make a new model. However still providing their conclusions even though they know they shouldn't do this. Eventually all of these papers somehow get published as facts in scientific books to educate young people and the bullshit continues.

Re: Entropy
is it true that entropy degrades DNA over time?

Re: Entropy
Yes, you are correct in that it is what I meant to say. The environment does not decay DNA to a less organized level as a function of time. Correct?

Re: Entropy
We are in a sense a solar powered organism. I'm curious to know why photosynthesis did not occur right from the beginning when single celled organisms emerged. Can anyone explain this?

Re: Entropy
Aging is a perfect example that we degrade over time. Entropy works by breaking us down over time where fitness decreases, diseases emerge, and we witness our own decay in the process.
This is chaotic to me and our structure definitely becomes disorganized until we die.

Genome Project.
Currently they cannot identify genes that express what the organism will produce in traits or features that makes it unique. Right now the data base is being built by comparing healthy individuals with people with known diseases or defects in structure by observing differences in sequences.
The common similarities of genes in species is that the structural and functional proteins is the same in all creatures. They do not know what mechanism actually is involved in what determines what the creature will look like.
