Researchers in Chile say they discovered a human footprint they believe is the oldest ever found in the Amer北汽,7座suv-人生之路,边走边忘是一种旷达icas.

智利的研讨人员标明,他们发现了他们以为的美洲前史最悠长的人类脚印。

Scientists involved in the fossil discovery said the footprint dates back a城镇居民医疗保险t least 15,600 years. Their results are reported in a study published in the scientific journal PLOS One.

参加这一化石赛尔号柯尔霍德发现的科学家们标明,这枚脚印能够追溯到至少1.56万年前,其研讨结果宣布在《公共科学图书馆期刊》这本科学期刊上。

The footprint was discovered in 2011 at the Pilauco excavation site in the city of Osorno. A student from Chile's Austral University found the footprint. Scie南昌地铁ntists worked for years to confirm whether the print could ha十亿少女ve come from a human species.

该脚印于2011年在奥索尔诺市的Pilauco考古现场被发现。来自智利南边大学的一名学生发现了这枚脚印。科学家们多年来一直在尽力承认这枚脚印是否来自于人类物种。

Mari牙龈胀痛吃什么药o Pino is a professor and geologist at Austral University's Institute of Earth Sciences. He helped examine the fossil. He said carbon dating methods w力帆轿车ere used to link the footprint to the same time period as plant material found in the area.

马利奥皮诺(Mario Pino)是智利南边大学地球科学研讨所的教授和地质学家。他协助研讨了该化石。他说,碳定年法发现这枚脚印同该区域发现的植物物质是同一时期。

Pino said his team used the print to estimate the general size, shape and structure of the human foot. Researchers believe it belonged to a barefoot man who weighed about 70 kilograms.

皮诺标明,他的团队使用这枚脚印来预算这只人脚的巨细、形状和结构。研讨人员以为它归于一位体重约7颜色代码0公斤的赤脚男人。

Karen Moreno is also with Austral Uni曹政奭怎样读versity 歌唱祖国歌词and a lead researcher on the pro服务ject. She said the print showed evidence of clearly formed toes and a ball at the back of the foot. This would be "consistent with what would happen to (a human) who tries to walk in t绝代艳后he mud," Moreno said.

克伦莫雷诺(Karen Moreno)也上任于智利南边大学,是这项研讨的首席研讨员。她说,这枚脚印能够看出显着的脚趾和脚后跟的圆球形。莫雷诺说:“这跟人类在泥泞中企图行走的状况共同。”

Pino said the man likely belonged to北汽,7座suv-人生之路,边走边忘是一种旷达 a species called Hominipes modernus, which is related to Homo sapiens. Homo sapiens is the species of human that exists today.

皮诺标明,该男人或许归于一种被称之为Homini原始传奇pes modernus的物种,它跟智人(Homo sapiens)相关。

Moreno said the latest find provides some of the oldest evidence of humans in the Americas. "Little by little北汽,7座suv-人生之路,边走边忘是一种旷达 in South America, we're starting to find sites with evidence of human presence," she saidadvantage. "But this is this oldest in the Americas."

莫雷诺标明,这一最新发现为美洲人类供给了一些最陈旧的依据。她说:“渐渐地咱们开端发现在南美洲的遗址有人类存北汽,7座suv-人生之路,边走边忘是一种旷达在的依据,这是在美洲发现的最陈旧脚印。”

The study states that the same 北汽,7座suv-人生之路,边走边忘是一种旷达area in Chile has also produced fossils providing information on other animals, including e北汽,7座suv-人生之路,边走边忘是一种旷达arly elephan省人民医院眼科王丽娅ts and an ancestor of American horses. The digging teams have also found evidence of invertebrates, as well as different forms of ancient plant life and wood material.

该研讨标明,智利同一区域发掘出来的化石还供给了其它动物的信息,包含前期大象和美国马的先人。发掘团队还发现了无脊椎动物的依据,以及不同方式的古代植物和木材。

Moreno said the researchers also found stone artifacts within the same layers of soil as the footprint. This, she believes, could provide more evidence to support a theory that human settlements existed in the Americas well before a group known as the "Clovis北汽,7座suv-人生之路,边走边忘是一种旷达" hunters.

莫雷诺标明,研讨人员还在发现脚印的同一土壤层中找到了石头制品。她以为这些还能够供给更多依据来支撑一项理论,即在克努维斯猎手好久之前,美洲大陆就有人类居住区存在。

The Clovis group was a prehistoric culture that many scientists believed阿奇霉素片 were the first to arrive in North America -- about 13,000 years ago.

克努维斯种群是史前文明,许多科学家以为这是在大约13000年前第一个抵达北美的文明。

But some scientists have suggested that artifacts discovered in recent years suggest other humans might have arrived in the Americas about 1,500 years earlier.

可是一些科学家现已提出,近年来发现的人工制品标明,其它人类或许大约早1500年前就现已抵达美洲。
