Jumping Genes Reveal Kangaroos' Origins
Nothing is more Australian than kangaroos. But these marsupials—along with a variety of others including the Tasmanian devil—have ancient roots in South America, a new study suggests. Exactly how these various marsupials, both living and extinct, are related has been murky.

One major exception is the large and economically important genus Quercus (oaks). Whereas differentiation patterns of the nuclear genome are in agreement with morphology and the fossil record...
متن کاملGenetic analyses reveal independent domestication origins of Eurasian reindeer.
Although there is little doubt that the domestication of mammals was instrumental for the modernization of human societies, even basic features of the path towards domestication remain largely unresolved for many species. Reindeer are considered to be in the early phase of domestication with wild and domestic herds still coexisting widely across Eurasia. This provides a unique model system for ...

The origins of music have intrigued scholars for thousands of years. In this article I discuss the role of experiments in discussions of these issues. I argue that potentially useful kinds of evidence are those that address the innateness and the specificity of different components of musical behavior.
