I’ve been informed that I’ve been at war for a while. I was surprised. Apparently, Perry Marshall thinks he’s been firing salvo after salvo at me…I just hadn’t noticed. My blog war with @pzmyers continues: https://t.co/dgjMeNvGRg — Evolution 2.0 (@cfingerprints) January 9, 2016 Oh, OK. I would just ignore him, but he’s presenting some fascinatingly…

This could get interesting. I’ve seen a lot of stories about this recent paper on the tardigrade genome: Horizontal gene transfer (HGT), or the transfer of genes between species, has been recognized recently as more pervasive than previously suspected. Here, we report evidence for an unprecedented degree of HGT into an animal genome, based on…

Well, cool. We’ve got preliminary analysis of the octopus genome, and it’s full of tantalizing goodies, but it’s very preliminary, and the Nature news and comment left me unimpressed. One of the things they seemed to think was a big deal was that Octopus has more genes than we do. Surprisingly, the octopus genome turned…

What’s going on, Scotland?

Scotland is going to formally ban the cultivation of genetically modified crops. Apparently, this was an easy step for them to take, because it’s the scientists who are explaining that this is a foolish move, and everyone knows you can just ignore the scientists. I also think it’s a matter of fearing the unknown. Scotland…

A defense of ENCODE?

Dan Graur has snarled at the authors of a paper defending ENCODE. How could I then resist? I read the offending paper, and I have to say something that will weaken my own reputation as a snarling attack dog myself: it does make a few good points. But it’s mostly using some valid criticisms to…

Death to Dollo’s Law!

Hint for science journalists: if the hook to get readers to pay attention to your story is to warn them to sit down because a 19th century “law” of evolution has been shown to be wrong, you’re going to irritate scientists, who will then write rude blog posts sneering at your writing. That’s the case…

The genetic load problem

Dan Graur has written a good summary of genetic load. It’s an important concept in population genetics, and everyone should be familiar with it…and this is a nice 2½ page summary with only a little math in it. I’ll try to summarize the summary in two paragraphs and even less math … but you should…

On the importance of luck

That paper that proposed that most cancers were due to bad luck, that is, that they were a consequence of biological factors that could not be controlled, has been surprisingly controversial. I thought it was a fairly unsurprising paper that confirmed what we already suspected, but wow, the furious pushback has been something to behold.…

Let’s slap ENCODE around some more

Since we still have someone arguing poorly for the virtues of the ENCODE project, I thought it might be worthwhile to go straight to the source and and cite an ENCODE project paper, Defining functional DNA elements in the human genome. It is a bizarre thing that actually makes the case for rejecting the idea…

Crusaders against GMOs

The New Yorker has a fascinating article on Vandana Shiva, a crusader against GMO crops. I’d never heard of her before, but apparently she has charisma and cult-like followers who hang on her every word, and her word is a rather religious opposition to scientific agriculture. Weirdly, I can agree with some of it. At…
