Kangaroos: Not Always Hoppers
June 2023
University of Bristol
Introduction
Ever wondered if all kangaroos were born to hop? Think again! Scientists from the University of Bristol and the University of Uppsala have hopped back in time to uncover that not all kangaroos stuck to their iconic bounce. Delving into the ancient world of kangaroos, this study, published in Alcheringa: An Australasian Journal of Palaeontology, reveals some kangaroo ancestors preferred striding on two legs or walking on all fours. So, next time you see a kangaroo, remember its relatives weren’t all about that hop life!

Hopping Through History - The Kangaroo's Tale
Why does it matter that some kangaroos didn't hop? Imagine a world where kangaroos stride and walk on all fours instead of hopping. This isn't a scene from a fantasy movie but a glimpse into Earth's past. The study of extinct kangaroos reveals a rich tapestry of evolution, showing us that the iconic hopping kangaroo is just one chapter in a much larger story. This narrative challenges our understanding of adaptation and survival, illustrating the diverse strategies life employs to thrive across changing landscapes. For you, this topic is a window into the complex, fascinating world of evolutionary biology and paleontology. It invites curiosity about how animals adapt (or don't) to their environments and what this means for our planet's future. Plus, who wouldn't want to imagine a kangaroo walking like a person or scampering on all fours?
