Gene Duplication and the Origin of Novel Biological Information: A Case Study of the Globins
We are well acquainted by now with the most fashionable neo-Darwinian model for the origin of novel biological information: gene duplication and divergence.
Does Gene Duplication Perform As Advertised?
In my previous post, I highlighted a recent peer-reviewed paper which challenged a key tenet of neo-Darwinian evolution — specifically, the causal sufficiency of gene duplication and subsequent divergence to account for the origin of novel biological information. In this follow-up blog, I want to consider some of the case-studies examined in the paper and relay some of the conclusions drawn.
A Response to Dr. Dawkins’ “Information Challenge” (Part 2): Does Gene Duplication Increase Information Content? (Updated)
[Editor’s note: This was the second installment of a three-part series. The full article, A Response to Dr. Dawkins’ “The Information Challenge”, can be read here.] In Part I, I demonstrated that specified complexity is the appropriate measure of biological complexity. In this section, I will show why merely citing gene duplication does not help one understand how Darwinian evolution can produce new genetic information. Dawkins’ main point in his “The Information Challenge” article is that “[n]ew genes arise through various kinds of duplication.” So his answer to the creationist question that so upset him is gene duplication. Yet during the actual gene-duplication process, a pre-existing gene is merely copied, and nothing truly new is generated. As Michael Egnor said Read More ›
Artificial General Intelligence: The Creation Exceeding the Creator
Is artificial intelligence at a tipping point, with AGI ready to appear in real time? Or is AGI more like many other themes of science fiction?
Geneticists Puzzled by Octopus’s Unique Genes: Seem to Have Appeared Out of Nowhere
“Evolution of novel genes”? Isn’t that the question at hand? Where do novel genes come from?
