A groundbreaking new study has pushed the timeline of life’s origin further back than previously thought. Researchers have ...

All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA. A study suggests that this organism likely lived on Earth only 400 million years after its formation. Further ...

New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world. The exact ...

A deep-rooted population structure emerged, suggesting modern humans, Homo sapiens, are the result of a population that split in two about 1.5 million years ago, and then, only 300,000 years ago, ...

This thread of genetic similarity connects us and the roughly 10 million other species in the modern world to the entire history of life, back to a single common ancestor more than 3.5 billion ...

Fish don’t exist. In her novel “Why Fish Don’t Exist,” Lulu Miller points out that a true “fish” clade containing an ancestor ...

But with the advent of molecular studies it has become clear that chimpanzees share a more recent common ancestor with humans, and are thus more closely related to us than they are to gorillas (e ...

All tetrapods descended from a common ancestor that just happened to have limbs with five digits. And over the eons of evolution following that, natural selection worked with variations on ...

share most likely originated from the same common ancestor. But it’s not a feature that we share with all vertebrates. Humans, other land vertebrates, and jawed fish have synovial joints.
