A global model for the origin of species independent of geographical isolation

The tremendous diversity of life continues to puzzle scientists, long after the 200 years since Charles Darwin's birth. However, in recent years, consistent patterns of biodiversity have been identified over space, time organism type and geographical region. Two views of the process of "specia...

Common fish species has 'human' ability to learn

Cracking the species code for plants

Plants are essential to our survival and that of most other animals on earth. It is easy to overlook this fact because they have become discretely embedded into our everyday lives. Plants provide us with food, medicines, and raw materials used by our industries. In spite of their importance, very ...

Biodiversity itself begets a species cascade, researchers say
