Originally from cameroon in africa , and once the star attraction at a florida zoo , ham was purchased by the united states air force to boldly go where only fruit flies , rhesus monkeys and a dog called laika had gone before .
Critics , however , are not yet ready to accept that the rhesus study proves caloric restriction works in primates .
但是,批评家们并不准备接受猕猴研究证明了低卡饮食适用于灵长类生物这一说法。
Although few similar studies of other primates have been conducted , recent research with rhesus monkeys has shown only very limited shrinkage with age .
尽管已经对其他灵长类动物进行过类似的研究,但只有最近对猕猴的研究才显示出随着年龄增长很有限的萎缩。
Scientists use rhesus monkeys to study hiv / aids drugs , research vaccines for rabies , smallpox and polio , and to study potential uses for embryonic stem cells .
Nevertheless , the evolutionary lineages leading to humans and rhesus monkeys diverged about 30 million years ago , leaving scientists in the dark about when the human pattern of brain aging might have begun .
