New research in West Africa shows that monkeys can climb trees using their feet, challenging previous assumptions about human evolution. A team of scientists from Ohio State University studied wild mangabey monkeys and found that they can bend parts of their feet to climb vertical tree trunks. This discovery may change our understanding of how humans evolved to walk on two legs.
Humans and chimpanzees diverged from a common ancestor between 6 and 7 million years ago. Reconstructing this ancestor is crucial for understanding human evolution, including the emergence of walking on two legs. One major question concerns where and how this ancestor moved through forests.
Chimpanzees are excellent tree climbers, thanks to their flexible ankles that can bend up to 45 degrees. Monkeys, on the other hand, have been thought to rely more on their arms for climbing. This distinction has influenced ideas about whether our common ancestor had feet like those of modern apes or monkeys.
Researchers from Ohio State University studied wild sooty mangabey monkeys in West Africa. They observed and measured how these monkeys climbed trees using their feet. The team found that the monkeys can bend parts of their feet to climb vertical tree trunks, just like chimpanzees do. This challenges previous assumptions about the importance of having a chimpanzee-like foot for climbing.
