Adaptive Evolution in Genomes

Adam Eyre-Walker has published a review of adaptive evolution in a few well studied systems: Drosophila, humans, viruses, Arabidopsis, etc. These organisms have been the subject of many studies that used DNA polymorphism, DNA divergence, or a combination of the two to detect natural selection in both protein coding and non-coding regions of the genomes.…

Dispatches from the Lab

After spending the last couple of years in front of a computer or in the fly room, I finally returned to the wet lab last week. The occasion: DNA isolation. Now, this isn’t any ole’ DNA isolation protocol. That would be too easy. Instead, I need some high molecular weight DNA, which means it takes…

Salty Beer

The Disgruntled Chemist was in Minnesota last week. He went out to a few local bars, and wrote about his encounters. Check out this one where met a girl who had martini olives in her beer. She claimed the olives were a substitute for the salt she normally put in her beer. Yeah, salt. SALT!…

Hey, That Could Have Been My Genome!

I’ve told you before that I once dreamt of becoming a conservation geneticist. I major turning point for me occurred after I had completed rotations during my first year of grad school. I had to decide between two different labs: in one I would use molecular markers to study the demography of a species of…

Mendel’s Garden #6

The sixth edition of Mendel’s Garden has been posted at The Voltage Gate. Like Ice Cube, MC Ren, and Eazy-E, this one’s straight outta Compton. Go check it out to see what NWA gots to do with genetics blogging. I know I’m pimpin’ my Raiders hat over a Jheri curl right now.

Phylogeny Friday – 15 September 2006

A few weeks ago I introduced the tree of life, albeit to some criticisms. The following week I zoomed in on one branch of that tree, the eukaryotes. I pointed out that animals were a mere twig in the eukaryotic tree, yet they have been the focus of a large amount of biological research. This…

Intelligently Designed College Football

Read this (via The Panda’s Thumb). Here’s a taste: TO THE CHAGRIN OF BAYLOR football fans, once steeped in the steady success of Grant Teaff during his Hall of Fame coaching career that concluded in 1992, their East-Central Texas school is now better known for its controversial role in the dubious effort to move the…

Grad Student Dooced for Blogging

This is old news, but I just heard about it. A microbiology graduate student at the University of Wisconsin has a blog. He finished his rotations and chose a lab. His to be advisor found out about the blog and read it. After concluding that the student did not really want to be in grad…

Speaking of the Devil

My last post was rather negative, and I tried my damnedest to not come across as an asshole. I think it’s important to realize, however, that as cool as evo-devo is, it won’t revolutionize evolutionary biology until it can be extended beyond animal body plans. Carl Zimmer commented that studies on social microbes may just…

Evo-Devo Doesn’t Really Explain Much

Doc Myers has another evo-devo post up; this one is on conserved dorsal-ventral patterning in the vertebrate and arthropod nervous systems. This stuff is fascinating, and Myers does a great job of explaining the research for a general audience. I’d imagine he’s an amazing teacher, as well. The entire field of evo-devo is really increasing…
