A new study published in BMC Evolutionary Biology shows that lower back pain is more frequent in people whose spines are similar in shape to those of chimpanzees. “[Our] study suggests that the pathological vertebrae of some people may be less well adapted for walking upright,” noted lead researcher Kimberly Plomp.
For millions of years there lived a rather large species of kangaroo in Australia called sthenurines. Weighing in at 550 pounds and featuring a 6'6" frame, these Pleistocene creatures must have been an awesome site — an animal made all the more remarkable by virtue of the fact that they walked around on their feet…
Pangolins, or Scaly Anteaters, are fascinating creatures. The eight pangolin species are found in Africa and parts of Asia, and they're the only mammals whose skin is covered in scales.
If you're quickly trying to define what sets humans apart from other primates, you might first point to our greater intelligence and our capacity for complex language. The next big difference is that we walk on two feet and stay out of the trees... except, as this video explains, it's not quite that simple.
This skull belonged to Australopithecus sediba, a new hominin species recently discovered in South Africa. The two million year old fossils are some of the most complete ever discovered, and they could rewrite our evolutionary family tree.
One of the most basic differences separating us from other apes is our ability to walk fully upright, and that goes back to the emergence of the Homo genus 1.9 million years ago. At least...that's what we used to think.
There are lots of possible explanations for why humans became bipedal, including changing ecosystems and food resources. But what if it was just so it was easier for early humans to beat the crap out of each other?
