Some of the oldest dinosaurs didn't have hollow bones, suggesting that skeletal air sacs evolved independently in three lineages: long-necked sauropodomorphs, meat-eating theropods and pterosaurs.

Fossils of a 70 million-year-old platypus relative called Patagorhynchus pascuali found in South America show that egg-laying mammals evolved on more than one continent.

Scientists have identified a mutant strain of clonal raider ants that look like miniature queens and evolved quickly because of a single "supergene" mutation.
