Ancient fossils reveal our oldest known ancestors had four eyes
Rare fossils discovered in southern China reveals that the earliest creatures with spines — ...
What do we have in common with fish, besides being vertebrates? The types of joints we (and most vertebrates) share most likely originated from the same common ancestor. But it’s not a feature that we ...
Yara Haridy, an evolutionary biologist at the University of Chicago, likes to stun people by telling them that our skeletons evolved from a jawless fish. "Much of what we have today has been around ...
Fossils of the prehistoric fish genus myllokunmingiid, more than 518 million years old, reveal that early vertebrates may have had four functional eyes. Researchers found that two large lateral eyes ...
A sea lamprey, which has no jaw, has the genetic code to do so, CU researchers find. Photo by Jeff Mitton A half-billion years ago, vertebrates lacked the ability to chew their food. They did not have ...
Immunostaining depicts collagen-2 (cyan) and nucleus (magenta) at the articulation in the little skate embryo's pelvic joint. Synovial joints are a key feature of most vertebrate skeletons, providing ...
Earth, rocks, evolution, and fish : background information to understanding fish evolution -- Glorified swimming worms : the first fishes : origins of chordates and the first vertebrates -- Jawless ...
Synovial joints, the lubricated cavity that lets the bones in our shoulders, knees, and elbows slide smoothly against each other, provide freedom of movement to all vertebrates. Scientists have known ...
The efficient architecture of our joints, which allows our skeletons to be flexible and sturdy, originated among our most ancient jawed fish ancestors, according to a new study. The efficient ...
