Environmentalists have warned that as the capital expands, it may spill over into the habitats of endangered species such as proboscis monkeys, orangutans and gibbons.

Orangutans and gibbons are tailless apes that still live in trees.

The ancestors of the Lufengpithecus did not move anything like this — their locomotion was more analogous to what we see today among gibbons in Asia — and humans developed their bipedalism afterward.

Skywalker gibbon couples wake up each morning and sing to each other, their voices echoing across the forest canopy of their home.

"Most fossil apes and their inferred ancestors are intermediate in locomotor mode between gibbons and African apes," adds Ni.
