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.
Fossils show that some ancient humans developed longer legs, different hip structures or thicker leg bones, consistent with modern-day humans. These adaptations made upright wâ¦alking easier and lessened the amount of energy required to walk upright.
