For Phillip Tobias, the 1994 find of Little Foot, the collection of Australopithecus africanus foot bones demonstrating features consistent with tree-climbing as well as an upright gait, contributed to calling the savannah hypothesis obsolete, stating Open the window and throw out the savannah hypothesis; it's dead and we need a new paradigm.

Most bipedal animals move with their backs close to horizontal, using a long tail to balance the weight of their bodies. The primate version of bipedalism is unusual because the back is close to upright (completely upright in humans), and the tail may be absent entirely. Many primates can stand upright on their hind legs without any support.
Some arboreal animals need to be able to move from tree to tree in order to find food and shelter. To be able to get from tree to tree, animals have evolved various adaptations. In some areas trees are close together and can be crossed by simple brachiation. In other areas, trees are not close together and animals need to have specific ...
Galago leaping. Vertical clinging and leaping (VCL) is a type of arboreal locomotion seen most commonly among the strepsirrhine primates and haplorrhine tarsiers.The animal begins at rest with its torso upright and elbows fixed, with both hands clinging to a vertical support, such as the side of a tree or bamboo stalk.
About 30 other people in California professionally climb trees to collect cones. Most travel thousands of miles for all of September, through October, and sometimes even November to December.
The WAIR hypothesis, a version of the "cursorial model" of the evolution of avian flight, in which birds' wings originated from forelimb modifications that provided downforce, enabling the proto-birds to run up extremely steep slopes such as the trunks of trees, was prompted by observation of young chukar chicks, and proposes that wings ...
"I didn't know the damn things could climb fences!!!!" "It's a good reminder not to let small pets or children roam around by themselves or play near the water in Florida," another wrote.
This requires the mudskipper to be wet, limiting them to humid habitats. This mode of breathing, similar to that employed by amphibians, is known as cutaneous breathing. They propel themselves over land on their sturdy fore fins. Some of them are also able to climb trees and skip atop the surface of the water. [6]
