What’s Behind Strange Drop in American Body Temperatures over the Past 200 Years?
by Carly Casella via Science Alert Headline Image: (Tim Hawley/DigitalVision/Getty Images) The human body is often said to rest at a healthy internal temperature of 37 degrees Celsius, or 98.6 degrees Fahrenheit. This average was established two centuries ago in France, and yet in the meantime, it seems our ‘normal’ physiology has changed ever so slightly. Early last year, researchers … Continue reading

Nested ‘DNA’ of Ancestor that Mated with Ancient Humans Discovered
Stephanie Pappas Live Science Today’s humans carry the genes of an ancient, unknown ancestor, left there by hominin species intermingling perhaps a million years ago. The ancestor may have been Homo erectus, but no one knows for sure — the genome of that extinct species of human has never been sequenced, said Adam Siepel, a computational biologist at Cold Spring … Continue reading
Is Extinction of the Human Race an Inevitability?
Though we may have a sense of indestructibility about us, there are a vast amount of possible ways we could be wiped out, just how resilient are we as a species ? Nick Longrich – a Senior Lecturer in Evolutionary Biology and Paleontolog at the University of Bath, England – delves into the possible fate of our species and our … Continue reading
One Key Hormone Might Have Set Us Apart From Apes
It’s not just about brain size. Even though you might not believe it on a crowded subway train, humans have a unique set of social skills that set us apart from other animals.
