Acceptance at last?

There’s something really notable about this image. Most cartoons feature the octopus as the villain; this one has the cephalopod representing the good guys, the 99%, strangling the villainous mammal. It breaks the stereotype!

Is it weird that I identified with the mollusc and felt a little happy uplift when I saw that?

A little sliver of restoration

Hey, I know the Elwha river! I think we stopped there on my honeymoon. Lovely place, the Olympic Peninsula. And getting even lovelier if they are ripping out unneeded dams and restoring the rivers. There’s something so satisfying about a timelapse of a dam being demolished.

How many genes does it take to make a squid eye?

This is an article about cephalopods and eye evolution, but I have to confess at the beginning that the paper it describes isn’t all that interesting. I don’t want you to have excessive expectations! I wanted to say a few words about it, though, because it addresses a basic question I get all the time, and while I was at it, I thought I’d mention a few results that set the stage for future studies.

I’m often asked to resolve some confusion: the scientific literature claims that eyes evolved multiple times, but I keep saying that eyes show evidence of common origin. Who is right? Why are you lying to me, Myers? And the answer is that we’re both right.
