Molecular Evolution:
A few months ago I wrote the following: I should point out that the mammalian Y chromosome is an anomaly in origin and sex determination. In fact, every single sex determination system and sex chromosome system that I know of...

Nobel Intent has an excellent summary of a paper in the PNAS pipeline on the origin of new exons in the human genome. The authors compared genes between humans and seven other vertebrates to identify newly arisen exons. They found...

David Haussler and colleagues have identified a 118 base pair sequence that has evolved really fast along the human lineage relative to the chimpanzee lineage (Carl Zimmer has a good review). In fact, this sequence differs by two base pairs...

Here are three interesting items that I don't plan on blogging, but are worth linking to: Here is a news release on indel variation in humans. SNPs are so 20th century. Deletions, duplications, and insertions are the molecular polymorphisms of...

Jacob at Salamander Candy has written the post that I have been meaning to write. With so much freely available sequence data in GenBank and loads of free software with which to analyze it, we should encourage the general public...

Here is some light reading for your Sunday: Mosquitoes sing to each other by flapping their wings. This paper reports sexually dimorphic responses to wing beat patterns in mosquitoes (PZ Myers has a good review). This leads me to wonder...

Andy Clark has written a review of comparative evolutionary genomics for Trends in Ecology and Evolution. His review deals with identifying functional regions of the genome and inference of both positively and negatively selected sequences. Clark is one of the...

Billy D (no, not that Billy Dee) is pimping an anti-evolution book by John Sanford. I refuse to link to outright liars, but you can find a link to Bill's blog here. More after the jump....

Don't expect much from me in terms of substantial posting. I'm getting prepared for the SMBE meeting, and devoting most of my time to finishing up some data analysis and putting together my talk. If you want to read about...

Razib linked to some press surrounding an unpublished (although presented at a conference) finding that an allele that causes deafness in homozygotes may allow wounds to heal better in heterozygotes. This appears to be another example of an allele simultaneously...

I'm trying to emerge from hibernation, and I'll hopefully have some good blogging material up in the next few days. In lieu of my own ideas, I'm going to link to what other people have written. Read them, because I...

Ian Musgrave has a good summary of genes appearing from non-coding DNA (ORFans) on the Panda's Thumb. I have written about ORFans here and here (dude's gotta link to himself sometimes). Ian's post is targeted at some claims made by...

Bora has been pushing the idea of publishing original research (hypotheses, data, etc) on science blogs. This post is part of a series exploring the evolution of a duplicated gene in the genus Drosophila. Links to the previous posts can...

Bora has been pushing the idea of publishing original research (hypotheses, data, etc) on science blogs. As a responsible researcher, I would need to obtain permission from any collaborators (including my advisor) before published anything we have been working on...

Via nodalpoint comes this UPGMA tree of sequence alignment algorithms from this paper. The first thing that comes to mind is that there are way too many sequence alignment methods. The second, it's kinda cool to see one method used...

We talk about molecular population and evolutionary GENETICS and GENOMICS. You know, the caliper measurement of a gene's evolvability in moles.
