Craig Venter, the infamous head of the Human Genome Project and who created the first “synthetic” cell, has been saying this stuff for years. It’s remarkable how ahead of the times he is, perhaps because he’s not beholden to an academic institution.
He claims that a “tree of life” is fallacious, that there is no junk DNA, and that the bare minimum genes necessary for a living cell still can’t be determined even after decades of research.
I hope that the authors of the new Extended Evolutionary Synthesis will admit the deficiency of outdated assumptions and reject dogmatic approaches to the theory, as implied by the author of the book reviewed in this article.
How could there be no junk DNA? There are plenty of inserted regions of repeating codons, between regions that are read (outside of replication). DNA replicators are very simple machines, they copy until they’re told to stop, I agree that any junk DNA in the human genome has been there for a very long time, but it’s not difficult to find single cell organisms that have introduced previously non-self DNA in their genome. If that DNA isn’t used besides replication then it’s junk is it not?
Also telomeres are pretty synonymous with junk DNA, until they aren’t, or is every shortening of the telomere removing information vital to a cells function?

Which theory exactly are we rejecting dogmatic approaches to?
