I am very excited to announce that the National Evolutionary Synthesis Center will be offering two travel awards for ScienceOnline 2010. These will be awarded for the best of evolutionary writing on the Web that features new and emerging evolutionary research in 2009. See below for the full announcement.

By Dr. M, on  July 30th, 2009 Adaptations, Carnivals & Link Love, Mating & Reproduction, Opinion & Editorial, Organisms constraints, design, Double XX, evolution, phylogenetic, predator, prey, sharks, size, Wired It’s been eight days since Miriam posted at Double XX This Wired piece on the 10 Worst Evolutionary Designs also made me want to smash some test tubes. It’s a stunningly inane list of animal adaptations that the author thinks are weird, uncontaminated by even the most basic knowledge of evolution. And the eight days . . . → Read More: Worst Evolutionary Designs? No! Brilliant Solutions to the Complexity of Nature and Constraints

The barnacle on top has been fertilized and the eggs are compressed into yellow pellets on either side of the body. The penis is sticking out from in between. The barnacle below has not been fertilized; the un-fertilized eggs are large yellow blobs. The testes are visible in both . . . → Read More: On the study of crustaceous genitalia

We here at DSN never shy away from writing about sex. Through reproduction, fitness is realized as progeny populate the landscape. Thus reproduction can be considered the backbone of evolution as traits are selected for and against, or perhaps not at all. Reproductive methods, the . . . → Read More: Introduction to Sex Week
This month’s Science Illustrated discusses how some deep-sea organisms are larger than thier shallow water cousins. The article dicusses the processes that lead to this pecular evolutionary trajectory. The latter includes some quotes from yours truly and dicusses my work from 2006.

This marine predator lived 500 million years ago and reveals clues to the origins of arthropods. © J B Caron Royal Ontario Museum Anomalocaris ruled the Cambrian seas but apparently so did a twenty centimenter cousin. Hurdia victoria, originally described in 1912, was known from just a jumble . . . → Read More: 100 Word Post: Hurdia victoria
I’m really enjoying The Oyster’s Garter these days. Miriam Goldstein keeps me updated with important nature stories like “When sponges ruled the Earth” 635 million years ago in the Early Cambrian epoch, just before the Cambrian explosion. Since more than 90% of modern sponges resemble those ancient sponges, perhaps there’s something to be said for . . . → Read More: She said spawning
