delinquent noun [C]. âº a âperson, usually âyoung, who âbehaves in a way that is âillegal or not âacceptable to most âpeople: âjuvenile delinquents.
Probably the major advantage of walking upright was that it freed the hands to use tools and carry (the pray). Another advantage is seeing further than on four legs, without the need to stop walking and raising oneself for a little while to look around ( like some animals do). Comments. Report.
Human walking is about 75% less costly than both quadrupedal and bipedal walking in chimpanzees. Some hypotheses have been supported that bipedalism increased the energetic efficiency of travel and that this was an important factor in the origin of bipedal locomotion. Humans save more energy than quadrupeds when walking but not when running. Human running is 75% less efficient than human walking.
