Remembrance Of Things Past Influences How Female Field Crickets Select Mates:

UC Riverside biologists researching the behavior of field crickets have found for the first time that female crickets remember attractive males based on the latter's song, and use this information when choosing mates. The researchers found that female crickets compare the information about the attractiveness of available males around them with other incoming signals when selecting attractive males for mating.

Evolution In A Test Tube: Scientists Make Molecules That Evolve And Compete, Mimicking Behavior Of Darwin's Finches:

A group of scientists at The Scripps Research Institute has set up the microscopic equivalent of the Galapagos Islands--an artificial ecosystem inside a test tube where molecules evolve to exploit distinct ecological niches, similar to the finches that Charles Darwin famously described in "The Origin of Species" 150 years ago.

Evidence Of The 'Lost World': Did Dinosaurs Survive The End Cretaceous Extinctions?:

The Lost World, Sir Arthur Conan Doyle's account of an isolated community of dinosaurs that survived the catastrophic extinction event 65 million years ago, has no less appeal now than it did when it was written a century ago. Various Hollywood versions have tried to recreate the lost world of dinosaurs, but today the fiction seems just a little closer to reality. New scientific evidence suggests that dinosaur bones from the Ojo Alamo Sandstone in the San Juan Basin, USA, date from after the extinction, and that dinosaurs may have survived in a remote area of what is now New Mexico and Colorado for up to half a million years. This controversial new research, published today in the journal Palaeontologia Electronica, is based on detailed chemical investigations of the dinosaur bones, and evidence for the age of the rocks in which they are found.

The Paleocene dinosaur paper is the most intruiging, although that authors has been arguing for Paleocene dinosaurs for years now. This newest paper is HUGE (146 pages) and I intend to go through it with a fine-toothed comb. I'll be eager to see the blogosphere reponse to this one.
