delinquent noun [C]. âº a âperson, usually âyoung, who âbehaves in a way that is âillegal or not âacceptable to most âpeople: âjuvenile delinquents.
Sahelanthropus may have walked on two legs. The oldest evidence for walking on two legs comes from one of the earliest humans known, Sahelanthropus. Walking upright may have helped this species survive in the diverse habitats near where it livedâincluding forests and grasslands.
In addition, use of walking sticks engages arm swinging and trunk movement, which is otherwise very limited with the use of a walker. Patients can discard use of walking sticks as soon as they feel secure, although some like the added support of the additional 2 legs.
