Human faces vary widely; some have wider set eyes while others have narrower ones, and noses come in all shapes and sizes. Now, scientists have found that our varied faces are the result of evolutionary pressure to make each of us as unique and easily recognizable as possible.
Could humans be on the verge of a major evolutionary transition? At least one researcher believes that's the case.
Researchers have found that our ancient ancestors' ability to move around and find new sources of groundwater during extremely dry periods in Africa millions of years ago may have been key to their survival and evolution.
Sloths may be slow but in the race of evolution, they're some of the fastest mammals out there.
When did oxygen-producing life forms first appear on our planet? It was a bit earlier than expected. Scientists have discovered that these life forms were actually present about 60 million years earlier than previously thought.
Muscles weren't always in the fossil record. In fact, animals once went without this feature. Now, though, scientists have uncovered the earliest evidence for animals with muscles, which may also provide the oldest evidence of muscle tissue.
Scientists are learning a bit more about how our ancestors evolved by examining a strange, walking fish.
It turns out that a specimen discovered in Africa about 90 years ago, called the Taung Child, may not have the human-like brain that scientists once thought.
Scientists may have just managed to re-activate the expression of an ancient gene that causes animals to develop a fish-like thymus. The findings reveal a bit more about how the immune system evolved over the course of evolution.
Scientists have found that not all African pygmy phenotypes have the same genetic underpinning, hinting that this is a more recent adaptation than previously thought.
Scientists have discovered that Tibetans, who thrive in the thin air of the Tibetan Plateau, may have a single DNA base pair change that dates back 8,000 that could explain how they adapt to thin air.
