The definition of orthograde posture can easily be derived from its roots “ortho-” meaning “upright” and “-grade” meaning “ascent.” This was true for the early Hominidae , whose transition to upright walking took place approximately six to seven million years ago evident in Orrorin tugenensis .

The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors).Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
The flying monkey in ancient China was sometimes simply referenced by the term 飛猱 (fēináo, literally meaning "flying monkey"), as in the poem "On the White Horse", by Cao Zhi (though, in this case, náo particularly implies a type of monkey with yellowish hair color): and also, in this case, the meaning of "fly" extends metaphorically to ...
Colugos (/ k ə ˈ l uː ɡ oʊ / [2] [3]), flying lemurs, or cobegos (/ k ə ˈ b iː ɡ oʊ / [4]), are arboreal gliding euarchontogliran mammals that are native to Southeast Asia. Their closest evolutionary relatives are primates .
In spite of the differences in leg number shown in terrestrial vertebrates, according to the inverted pendulum model of walking and spring-mass model of running, "walks" and "runs" are seen in animals with 2, 4, 6, or more legs. The term "gait" has even been applied to flying and swimming organisms that produce distinct patterns of wake vortices.
Centipedes have one pair of legs per body segment, with typically around 50 legs, but some species have over 200. The terrestrial animals with the most legs are the millipedes. They have two pairs of legs per body segment, with common species having between 80 and 400 legs overall – with the rare species Illacme plenipes having up to 750 legs.
Kinesiology (from Ancient Greek κίνησις (kínēsis) 'movement' and -λογία-logía 'study of') is the scientific study of human body movement. Kinesiology addresses physiological, anatomical, biomechanical, pathological, neuropsychological principles and mechanisms of movement.
The smallest flying vertebrates are the bee hummingbird and the bumblebee bat, both of which may weigh less than 2 grams (0.071 oz). They are thought to represent the lower size limit for endotherm flight. [citation needed] The smallest flying invertebrate is a fairyfly wasp species, Kikiki huna, at 0.15 mm (0.0059 in) (150 μm).
