I seem to develop these weird, unfounded hatreds of various things. For example: I hate blue dinnerware. Not every shade of blue dinnerware (I LOVE prussian blue glassware), but I severely dislike those particular gray-blue shades reminiscent of country Americana. I can’t explain it–the mere sight of plates like these makes me angry. I would . . . → Read More: I hate plants, but seagrasses are awesome

The National Evolutionary Synthesis Center is trying an experiment this year for Darwin Day. In 2011 we are taking Darwin Day on the road. We will be sending our scientists to small towns and communities (i.e., places that wouldn’t otherwise have Darwin Day celebrations) around the United States to share their research and talk to . . . → Read More: Darwin Day Road Show

Using a combination of genes and morphological traits they rejected some of the ideas that were foundational to barnacle biology and taxonomy, while giving new support for other . . . → Read More: Barnacle Evolution I: Phylogeny Served Without Plates

On land, mammals were oppressed under dinosaur Republican rule. Massive reptiles and ammonites, long since extinct, dominated the oceans. Under the reign of these giants, the lizardfishes were mere fledglings. Today, the 256 known lizardfishes represent an . . . → Read More: Of eyes and sex in lizardfishes

Deuterostomy is characterized by several developmental characteristics including radial, indeterminate cleavage, a posterior position of the blastopore (deuterostomy=”second mouth”), enterocoelous coelom formation and a tripartite adult body plan with a post-anal tail. At least this is what I was taught “growing up”. Three . . . → Read More: What in Darwin’s Name Are Chaetognaths?!
