Why have mass extinctions of species occurred since the late Proterozoic (from 580 million years ago) and repeatedly through the Phanerozoic? Integral to these extinctions were abrupt changes in the physical…
In the last ten years more than 1000 new species have been discovered in the Greater Mekong region. The new species are the focus of the Wild Mekong report from WWF, demonstrating the unique bio-diversity…
We currently face a biodiversity and extinction crisis as human population pressures and climate change combine to push our natural environments to the limit. Because our urban and agricultural activities…
In his 2011 ASSA Cunningham Lecture this month, food policy expert Professor Tim Lang suggested that we “experiment” with alternative diets to reduce our meat and dairy consumption. Lang suggested that…
When we think of the last 50,000 years of prehistory, particularly the “Ice Age”, extinct species such as the woolly mammoth and woolly rhinoceros often spring to mind. Did humans bring about the extinction…
The United Nations has set Halloween as the day when homosapiens are estimated to reach seven billion, up from six billion in 1999 and five billion in 1987. Two centuries ago there were one billion people…
All over the planet, a new wave of exploration and exploitation is taking place. Bioprospectors are searching for new and useful biological samples and compounds from previously unstudied animals and plants…
Our planet is on the precipice of a sixth mass extinction event. But unlike the five previous mass extinctions, this one is man-made: a global biodiversity crisis in which species are disappearing three…
Fossils from a new species of woolly rhinoceros found in Tibet have the potential to rock several cherished theories. According to the authors of a new paper published today in Science, the rhino showed…
Does climate change seriously threaten to wipe out the human species if left unchecked? Examining our evolutionary past suggests it might once have been the perfect catalyst for our extinction. But now…
