Where do we come from? How did all the diversity of life originate? These are some of the most intriguing biological questions we still struggle to answer. In order to understand the processes that produce the diversity of life on Earth, evolutionary…

Our culture generally assumes that human beings are a monogamous species, with two people committed to one another for a long-term relationship. Scientifically, the existence of monogamy seems counter-intuitive. One of the principles of evolution is that…

If superior design is what you seek, look no further than your own front yard. Plants and photosynthetic microbes can convert sunlight and air into energy, with an energy efficiency that would make a Prius owner blush. In a less dramatic, but no less…

-- To unearth the secrets of our human origins, scientists are delving deep into the prehistoric record to find the last common ancestor of great apes and humans, while simultaneously looking in more recent history to define when and where modern humans…
