The Kangaroos That Didn’t Hop

Extinct kangaroos displayed more diverse locomotion patterns than their modern counterparts, including quadrupedal bounding, climbing, and slower hopping, according to a review by researchers from the University of Bristol and the University of Uppsala. The study suggests that the high-speed endurance hopping seen in modern kangaroos was likely rare or absent in their ancestors, with many extinct species adopting alternative forms of movement, such as bipedal striding.
