I’m sure by now you’ve heard of the ginormous spider web that was spun in Texas. The thing was huge — 200 yards long — and it was spun by multiple different species. That interspecific collaboration got Bill Poser thinking, so he blogged about it at Language Log: The web covers hundreds of square meters.…

Lamarck was Wrong

Shelley’s posted some pictures of nerd cakes. She calls ‘em geek cakes, but I see no headless chickens. Anyway, I’ve got my own little nerd cake: We had it made for a party we threw during recruitment weekend for our grad program this past spring. Sadly, the icer responsible for the art couldn’t spell, so…

Genomic Phylostratigraphy

According to this press release Trends in Genetics (TIG) is “the most established monthly journal in Genetics”. I have no idea what that means, but if I were asked to name the top journals in genetics, TIG wouldn’t crack the top four. In fact, here is my top four: Nature Genetics PLoS Genetics Genetics Heredity…

I’d be remiss to not mention this paper from Hopi Hoekstra’s group after I previously discussed the anti-evo-devo paper she wrote with Jerry Coyne. The premise of the paper from Hoekstra and Coyne is that Sean Carroll overplays the importance of cis-regulatory changes in the evolution of form. Well, Hoekstra and colleagues mapped the genes…

Evo-Devo Revisited

I thought I had come to grips with evo-devo. Then along come Hopi Hoekstra and Jerry Coyne to call shenanigans on Sean Carroll’s model of evo-devo. This is nothing new for Coyne, but I can’t recall Hoekstra ever getting involved in the debate before now. Before we get to Hoekstra and Coyne, let’s allow Carroll…

Evolution Education

Last month’s issue of Evolution (aka Evolution Int J Org Evolution, aka Evolution (Lawrence Kansas), aka some other confusing way of referring to the journal published by the Society for the Study of Evolution) contains two articles on teaching evolution. The first is on creating museum exhibitions to showcase evolutionary biology. The article focuses on…

Sorry, dude, but it has to be said. In a feature from the March issue of Seed Magazine (one that doesn’t appear to be available online), Jonah Lehrer profiles six young scientists dubbed “The Truth Seekers”. In his description of Pardis Sabeti, Jonah makes the common error of conflating evolution with natural selection. Sabeti has…

Phylogeny Friday – 27 April 2007

This week’s phylogeny comes from this paper on molecular dating of speciation events. I won’t be addressing molecular dating per se, but I will be dealing with what molecular clocks tell us. Like, do they actually reveal the speciation time of a pair of species?

GAME PREVIEW | PRESS CENTER Yesterday’s game between Corporate and Charles Darwin was a battle between free market capitalism and the greatest naturalist of all time. The Corporate team is loaded with the world’s top pharmaceutical and chemical companies. Darwin is the author of important works such as On the Origin of Species and The…

Phylogeny Friday – 30 March 2007

Mammals did not rapidly radiate after the K/T boundary. That’s the punch line of a paper published in this week’s issue of Nature. This has been all over the news, including the New York Times twice (#1 and #2). You see, there’s this idea that when the dinosaurs (technically, the non-avian dinosaurs) disappeared, mammals quickly…
