Ancient microbes offer clues to how complex life evolved
A new study published in Science Advances reveals a surprising twist in the evolutionary history of complex life. Researchers at Queen Mary University of London have discovered that a single-celled organism, a close relative of animals, harbors the r.....»»
Idiotfruit and tree kangaroos: Why the ancient rainforests of Queensland"s Wet Tropics are so distinctive
In Queensland's northern reaches lie the Wet Tropics, spanning about 450 kilometers between Townsville and Cooktown. These mountainous rainforests are a relic of the ancient continent of Gondwana, dating back million of years when Australia and parts.....»»
Did plague really decimate Neolithic farmers 5,200 years ago, as a new study suggests?
Around 5,200 years ago, plague was not just present but common in six generations of one Swedish family, according to a new study. The researchers analyzed both the ancient DNA of these people's skeletal remains and the pathogens that left traces in.....»»
