Cedars-Sinai Surgeon Uses Modern Technology to Solve Prehistoric Mystery of Saber-Toothed Cats

Cedars-Sinai

Orthopaedic surgeon Robert Klapper, MD, spends his days repairing worn-out hip joints. But examining the hip joint of an animal extinct for more than 12,000 years presented an entirely new challenge—and shed light on a long-running debate within paleontology about saber-toothed cats. Klapper is working with the paleontologists at the La Brea Tar Pits and Museum to unravel the mystery of how these giant cats lived and roamed. Using Cedars-Sinai’s most advanced CT scan machines, Klapper studied the pelvis and femurs of an extinct cat.

Brain Size of Human Ancestors Evolved Gradually Over 3 Million Years

University of Chicago Medical Center

Modern humans have brains that are more than three times larger than our closest living relatives, chimpanzees and bonobos. Scientists don't agree on when and how this dramatic increase took place, but new analysis of 94 hominin fossils shows that average brain size increased gradually and consistently over the past three million years.

Researchers Pose Revolutionary Theory on Horse Evolution

New York Institute of Technology

Scientists have long wondered how the horse evolved from an ancestor with five toes to the animal we know today. While it is largely believed that horses simply evolved with fewer digits, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) pose a new theory that suggests remnants of all five toes are still present within the hooves of the horse.

Mass Extinctions Remove Species but Not Ecological Variety

University of Chicago

Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall "functional" diversity--how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks. University of Chicago scientists documented this surprising trend in a study on extinctions published Jan. 5 in the Proceedings of the National Academy of Sciences.
