Giant panda’s bamboo diet still looks surprisingly carnivorous — ScienceDaily

Giant pandas are unusual in being extremely specialized herbivores that feed almost exclusively on highly fibrous bamboo, despite belonging to a clade (Carnivora) of primarily flesh-eating carnivores. But a study suggests that the switch to a restricted vegetarian diet wasn’t, in some respects, as big an evolutionary leap as it seems.

Duck-billed dinosaurs: Evolutionary bursts led to weird and wonderful head crests — ScienceDaily

The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 ton giants so successful? A new study shows that their special adaptations in teeth and jaws and in their head crests were crucial, and provides new insights into how these innovations evolved.

Dolphin ancestor’s hearing was more like hoofed mammals than today’s sea creatures: CT scan of 30-million-year-old fossil indicates echolocation evolved more than once — ScienceDaily

Paleontologists are looking into the evolutionary origins of the whistles and squeaks that dolphins and porpoises make — part of the rare echolocation ability that allows them to effectively navigate their dark environment.

At Nature: Carl Woese’s archaea are “shaking up the tree of life” | Uncommon Descent

If the most complex cells descended from the least complex ones (which is what it looks like), that’s not really something many researchers want to hear.
