Cognitive Elements of Language Have Existed for 40 Million Years
Humans are not the only beings that can identify rules in complex language-like constructions - monkeys and great apes can do so, too, a study at the University of Zurich has shown.

DNA Study Reveals Insights About the Scimitar-Toothed Cat
Along with the woolly mammoth and the giant ground sloth, the sabre-toothed cats were probably among the most famous animals that lived during the Pleistocene Epoch and went extinct before the end of last ice age. Over the years, sabre-toothed cats have also been the subject of many research projects.

Seeking Ancient Rainforests Through Modern Mammal Diets
Closed-canopy rainforests are a vital part of the Earth's modern ecosystems, but tropical plants don't preserve well in the fossil record so it is difficult to tell how long these habitats have existed and where rainforests might have once grown.

The Evolution of Colourful Feathers Shines Light on the Missing Link in Evolution by Natural Selection
There's a paradox within the theory of evolution: The life forms that exist today are here because they were able to change when past environments disappeared. Yet, organisms evolve to fit into specific environmental niches.
