Only 1,280 Reproductive Ancestors of Humans Once Roamed Earth, Gene Study Suggests
Humankind struggled to survive during a 100,000 year period during the early Pleistocene, according to researchers who used a computer model to discover a severe population bottleneck in our species’ ancient past. The bottleneck occurred between 813,000 years ago and 930,000 years ago, and reduced an ancestral human species to less than 1,300 breeding individuals.…

One of Australia’s Tiniest Mammals Is Heading Straight for Extinction If We Don’t Act Now
They weigh around 15 grams, the same as a 50 cent coin. They devour vast quantities of insects. And they’re in real trouble. Our new research has found the critically endangered southern bent-wing bat is continuing to decline. Its populations are centred on just three “maternity” caves in southeast South Australia and southwest Victoria, where…
