Using a combination of technologies and comparisons with living animals, the researchers were able to study patterns of wear and tear on the mammals’ teeth in fossils. The observations showed that some...

Paleontologists have discovered that an improved sense of smell jumpstarted brain evolution in the ancestral cousins of present-day mammals.  The findings help explain why mammals evolved such large and complex brains, which in some cases ballooned 10 times larger than relative body size.  The researchers constructed fossils of two Early Jurassic Period mammals to provide evidence that the mammalian brain evolved in three major stages.  First by improvements in sense of smell...
