What? You still haven’t told Facebook you like Denim and Tweed? But then how else will it know to send you ads for, um, obligate pollination mutualism?

• Gotta start somewhere. The simplest possible biological eye—and the starting point for the evolution of more complex models—may have been found in brachiopod larvae.
• Look out below! In Palmyra Atoll National Wildlife Refuge, introduced coconut palms are literally bombing the natives into extinction.
• In case you missed it. The Carnival of Evolution is out at Genome Engineering.
• Herpetologist porn. Anolis osa has just been differentiated from Anolis polylepis based on what a leading Anole scholar calls their “man parts.”
• Big cats, but no longer the top dogs. With population declines of more than 90 percent since 1960, lions are in danger of extinction in the wild.
• But wait, there’s more. It’s not looking so great for every other known species, either.
