Phylogenetics:
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...

And they're doing it open access style. Jonathan Eisen and Michael Eisen have each published papers in the PLoS journals using newly available genome sequence data. Jonathan is lead on author on the paper describing the genome sequence of the...

Last week's Phylogeny Friday introduced the three domains of life: bacteria, archaea, and eukaryotes. The bacteria and archaea are commonly referred to as prokaryotes, although that creates a paraphyletic taxon. Today, we will focus on the eukaryotes (organisms with nuclei...

Phylogeny Friday is back, bitches! Katherine's gotta add me to her list ASAP. In the glorious return of PhyFridays, I give you the root of the tree of life. In the upcoming editions we'll zoom in on a few parts...

You may have thought that Orin Scrivello was the worst dentist ever. Well, have I got a story for you. This dentist isn't a sadist, and his follies were far from intentional. But the implications of his conduct greatly...

I wrote about the possibility of gene trees and species trees giving conflicting information in a previous Phylogeny Friday. In that example, the discordance was due to balancing selection maintaining multiple alleles across species boundaries. But can incongruities between genetic...

As I mentioned previously, I'm busy preparing some data for a meeting next week. I don't have much time to devote to Phylogeny Friday, so I'll be sharing some of my own data with you. This data is nothing special;...

I've been busy this past week (and I'll be busy in the next couple of weeks to come), so I don't have much time to post to evolgen. For this reason this week's Phylogeny Friday is a recycled post from...

Is it possible that you are more closely related to a chimpanzee than to another human? Ok, that's a bit of a loaded question. It depends on how we define 'related', or, more specifically, what we are measuring. If, for...

Carl Zimmer (one of the best general audience science writers) has a post on his blog on how the human immune system differs from that of other primates and even other apes. It's a good example of why biomedical...

Over at my old site, I lamented the apparent death of distance based tree building algorithms. Just as all of life on earth can be divided into three domains, phylogenetic methods can be split into three groups: distance based, maximum...

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...

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...

It's not the best way to kick of a new blog theme -- on Friday night with a half-hearted entry -- but I promised last week that I would begin Phylogeny Fridays today, so I need to deliver. For the...

After a short, and dirty, run, the evolgen Double Entendre Friday has shuffled off its mortal coil. I just can't keep it up week after week (double entendre not intended). Of course, if I do come across something particular distasteful...

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