人类和猩猩衰老的速度相同

虽然科技和医学不断创造奇迹,人类不断取得进步,但是人类和黑猩猩的死亡率竟然不相上下。

With our clothing, high-rises, technology and more, we humans would seem to be animal kingdom outsiders, existing outside the norm. But despite all our advances, it turns out we age and die at the same rate as other primates.
我们穿衣服,建造高楼大厦,拥有科学技术,还有其他方方面面都使人类看起来不属于动物王国,脱离了动物的范畴。然而,尽管我们取得了各种各样的进步,我们还是在以和其他灵长类动物一样的速度衰老、死亡。
The finding, published in the latest issue of Science, shows how strong our ties to chimpanzees, gorillas and other primates is and counters the long-held belief that, with our relatively long life spans and access to modern medicine, we age more slowly than other animals.
最近一期《科学》杂志上发表的一项发现证明了人类与黑猩猩、大猩猩以及其他灵长类动物之间的紧密联系,同时也反驳了长期以来人们一直持有的观点——因为人类的寿命相对较长且可以享受现代医疗带来的福音,所以人类衰老的速度要比其他动物慢。
"We are making a conceptual point that humans are really very much more similar in their aging patterns to other primates than anyone had suspected before," co-author Susan Alberts, a professor of biology at Duke University, told Discovery News.
这项发现的合作者、杜克大学生物学教授苏珊·艾伯茨告诉《探索新闻》:“我们要确立的是一种概念性的观点,那就是在衰老模式方面,人类与其他灵长类动物非常相似,其相似度是以往任何人都不曾想到的。”
"Humans have been a bit of an enigma," added project leader Anne Bronikowski. "We live much longer than would be expected based on our body sizes, our morphology, our maturation rates, and our reproduction rates. When comparisons have been made between humans versus lab or domestic animals (such as horses, dogs, rats and mice) humans have had slower rates of aging than these other species."
这个研究项目的负责人安妮·布罗尼科夫斯基补充说:“人类就像一个谜。考虑到我们的身材大小、形态学的理论、成熟率以及生殖率等方面的因素,人类的寿命确实很长。与实验动物和家畜(例如:马、狗、大老鼠和老鼠等)的对比证明,人类衰老的速度慢于其他物种。”
But no one until now had previously brought together detailed datasets on aging and mortality for multiple wild-living primates, and compared those to data on humans.
但是,在此之前,没有人对多种野生灵长类动物衰老和死亡的详细数据进行搜集整理,并将其与人类的有关数据进行比较。
Bronikowski, an associate professor in the Department of Ecology, Evolution and Organismal Biology at Iowa State University, and her colleagues combined data from long-term studies of humans and these wild primates: capuchin monkeys from Costa Rica, muriqui monkeys from Brazil, baboons and blue monkeys from Kenya, chimpanzees from Tanzania, gorillas from Rwanda, and sifaka lemurs from Madagascar.
布罗尼科夫斯基是爱荷华州立大学生态学、进化论及有机体生物学系的副教授,她和同事们综合了长期以来对人类和灵长类动物研究的各种数据。这些灵长类动物包括:哥斯达黎加的僧帽猴、巴西的绒毛蛛猴、肯尼亚的狒狒和蓝猴、坦桑尼亚的黑猩猩、卢旺达的大猩猩以及马达加斯加的马达加斯加狐猴。
All of these primates and humans, experience high infant mortality, followed by a period of low mortality during the juvenile stage and an extended period of increasing age-specific mortality during mid to late life. These patterns apply to many animals, however, so the researchers took their analysis of primates a step further by focusing on the initial mortality rate (IMR) and the rate at which the probability of dying increases with age.
所有这些灵长类动物和人类都是婴儿期死亡率较高,幼年期的死亡率较低,在中老年期这个较长的时间段里,由于衰老,死亡率又不断增高。然而,许多动物都遵循这样的模式,所以研究人员把他们对灵长类动物的分析更进了一步,集中分析最初的死亡率(IMR)和随着年龄的增长死亡的可能性增长的比率。
"We found that human females cluster with gorillas in infant mortality, and that human females cluster with chimps, sifakas, baboons, and muriquis in their rate of aging, so human females are really right in there with other primates in these two measures," Bronikowski said.
布罗尼科夫斯基说:“我们发现,人类女性在婴儿死亡率方面与大猩猩大致相同,而在衰老的速度方面则与黑猩猩、马达加斯加狐猴、狒狒以及绒毛蛛猴不相上下,所以,在这两个方面,人类女性确实与其他灵长类动物没有什么区别。”
Men, on the other hand, appear to age more slowly than males of primate species in the wild, but the differences are minimal, according to the scientists.
另一方面,这些科学家说,与野生状态下的雄性灵长类动物相比,人类男性衰老得较慢,但是这种差距是微乎其微的。
"There is no evidence there that would make a person say, 'Wow, human males look really unique in their aging patterns,'" Bronikowski continued. "Moreover, the human males share similar aging features with the females of other primate species in this study."
