How we got here

It’s been 25 years since Gould’s Wonderful Life: The Burgess Shale and the Nature of History crystallized the debate over the importance of contingency in evolution, most famously illustrated by his metaphor of “replaying the tape of life”. If we could roll back the history of life on earth and restart it in the pre-Cambrian,…

We do, however, require a formal seminar of our biology undergraduates in their senior year. We must make sure none of them ever see this comic!

We’ve been invaded by a pair of groundhogs who have taken up residence under our deck, and are apparently dining grandly on our weedy overgrown backyard. They’re evasive, though, and I’ve only got this one poor shot of one of them resting in the dappled shade. OK, here’s a clearer shot of what they look…

2 + 2 = 17, for certain values of 2

A while back, I responded to Behe/Luskin’s claim that his model proving the impossibility of evolution of chloroquinone resistance was vindicated. I pointed out (as did Ken Miller) that showing that a particular trait required multiple point mutations did not affect the probability in the naive way that Behe and Luskin calculated — in particular,…

The most brilliant business plan ever

Take a look at the kind of profit you can make from various businesses. This is pretty good money. We all know Apple’s business model is to build cool gadgets with high end stuff inside that it then sells at a high markup for premium design and ease of use — they’re at least creating…

The fuddy-duddies still thrive

Kate Clancy comments on a ‘satire’ published in a serious journal. Genome Biology published a satirical piece by Neil Hall today, and since I’m American and he’s British I don’t find it funny. No wait, it’s that I’m female and he’s male. Or maybe that I’m junior and he’s senior. I’ve got it, it’s because…

We’re doomed. The Pacific striped octopus is exhibiting complex social behaviors. Panamanian biologist Aradio Rodaniche first reported the Pacific striped octopus in 1991 off the coast of Nicaragua, noting its strange behavior—living in groups of possibly up to 40, laying multiple egg clutches, and mating face-to-face and sucker-to-sucker. Most other octopus species, for instance, come together…

Next week, I think I will!

Mary’s Monday Metazoan: Cartilage!

I like this hypothesis

But we have to be clear that it is only a hypothesis at this point. I was reading about domestication syndrome (DS) — selecting animals for domestication has a whole collection of secondary traits that come along for the ride, in addition to tameness. We are selecting for animals that tolerate the presence of humans,…
