Evolution stole birds' sweet tooth, hummingbirds got it back
Cambridge, Mass. (UPI) Aug 22, 2014
Genome sequencing over the last decade has revealed birds to lack the gene T1R2, one of two that combine to allow animals to taste sugar. Alligators, on the other hand - one of birds' closest relatives - have both the necessary sweet tooth genes. The discrepancy suggests that as birds split off from dinosaurs on the evolutionary family tree, they lost their taste for sugar. Yet, hummingbirds are nectar fiends - they can't get enough. But why? And how? Most vertebrates have three taste-relate ... read more

Siberian fossils suggest all dinosaurs had feathers
Over the last two decades, paleontologists have amassed more and more evidence of the prevalence of feathers among theropod dinosaurs, a group of raptor-like meat-eaters. Scientists believe birds evolved from therapods, and some findings even suggest therapods could fly even before birds evolved. ... more

500-million-year-old fossils reveal creature on the way to evolving jaws
For more than a century, scientists have searched for fossils that offer new clues as to when and how our earliest ancestors split off from their invertebrate brethren and began developing bones. But finding intact early vertebrates, much less well-preserved invertebrates, is exceedingly difficult - their soft bodies easily malformed by the pressures shifting rocks and weather. ... more
