|Birdsong study pecks theory that music is uniquely human
Posted: 27 Dec 2012 05:01 AM PST
A bird listening to birdsong may experience some of the same emotions as a human listening to music, suggests a new study on white-throated sparrows. The new study found that the same neural reward system is activated in female birds in the breeding state that are listening to male birdsong, and in people listening to music that they like.
|Two new species of orchid found in Cuba

Researchers have discovered two new species of Caribbean orchid. The Caribbean islands have been natural laboratories and a source of inspiration for biologists for over two centuries now. Suffice to say that the studies by Charles Darwin and Alfred Russel Wallace in the tropical archipelagos contributed to the emergence of the theory of evolution. In this case, biologists have discovered two new species belonging to the orchid family (Orchidaceae: Laeliinae) in Cuba. They have been called Tetramicra riparia and Encyclia navarroi.
