Another Truism Dies
A new paper can be found at Phys.Org undermining the idea that what drives evolution is the “decoupling” of DNA with phylogenic structures. This idea is implicit in the twin ideas of pseudogenes and gene duplication: both allow the DNA to become “uncoupled” from the structures they code for and so RM becomes permissible. Well, this paper shuts down this idea. Given the success of cichlids, understanding the evolution of these two jaws has become an important line of inquiry for biologists. “We’re trying to gain a better understanding of the origins and maintenance of biodiversity,” says Albertson. Researchers have long thought that the two sets of jaws are evolutionarily decoupled and can evolve independently of one another, pushing the Read More ›

Central Dogma: Reasons for Further Thought
For about a year now, from reading various news items on newly published science articles, I’ve begun to consider not DNA, but RNA, the real driver of life. I think that DNA’s essential role is that of information storage–a hard drive, while RNA is like the BIOS system–it tells the “system” what it should be doing. I’ve been waiting for the right article to come along to present this newer view of genomic life. Well, it appears that the ‘right article’ has come along. This is from Phys.Org and this is the pdf online version of the article. From the Press Release via Phys.Org: Cells contain machinery that duplicates DNA into a new set that goes into a newly formed Read More ›
