‘dragon man’ cranium could help uncover homo sapiens’ origin

“龙人”头骨或有助于掀开智人来历之谜

the world has taken a critical step toward figuring out the origin and evolution of homo sapiens, the species all living humans belong to, with chinese researchers announcing the discovery of a new species of ancient human they have dubbed “dragon man”.

讨人员宣告发现了一种被称为“龙人”的古代新人种,这标志着世界朝着弄清一切现存人类所属的智人的来历和进化迈出了要害的一步。

more closely related to modern humans than neanderthals, the species researchers officially named homo longi sp nov may lead to a rethinking of human evolution.?the announcement was made based on the results of research on a skull that is at least 138,000 years old.?

与尼安德特人比较,龙人与现代人类的联络更为紧密,研讨人员将其正式命名为“龙人”,这可以会引发我们对人类进化的新的思考。该发现根据对一个至稀有着13.8万年前史的头骨的研讨成果。

it was reportedly unearthed in 1933 when a bridge was built over the songhua river in harbin, heilongjiang province. the city was under japanese occupation at the time, and the man who found the skull concealed it at the bottom of an?abandoned?well for safekeeping.

据报导,该头骨出土于1933年,是我们在黑龙江省哈尔滨市松花江上建筑桥梁时发现的。其时,这座城市正处于日本的占据之下,发现头骨的人把它藏在了一口废井中,以便妥善保管。

the fossil was not recovered until the third generation of the anonymous man’s family learned of the secret before his death, according to studies the researchers published in the journal the innovation on friday.

据研讨人员上星期五宣告在《立异》杂志上的研讨,直到这位发现头骨的不出名男人在去世前将这个隐秘告诉了他的孙子,这块化石才得以被我们发现。

the fossil was then donated in 2021 to the geoscience museum of hebei geo university in shijiazhuang, capital of hebei province.

2021年,化石的一切者将它捐赠给了位于河北省会石家庄的河北地质大学地球科学博物馆。

the research team used?sophisticated?geochemical analysis, including rare earth elements, strontium isotopic ratios and x-ray fluorescence, and direct uranium series dating on the skull, according to a media release issued by the university on saturday.

周六,据河北地质大学发布消息称,该研讨小组使用前沿的地球化学分析(包括稀土元素比照、锶同位素比值分析、x-射线荧光谱学分析、以及铀系测年法)仇人骨进行测定。

“although it is impossible to pin the skull to an exact location with currently available technology, all the evidence suggests that it was from a bed of lacustrine sediments aged between 138,000 and 309,000 years ago in the harbin region,” said ge junyi, one of the members of the research team and a geochemist from the chinese academy of sciences.

我国科学院的地化专家、科研团队成员葛飘逸说:“尽管如今的技能还缺乏以把这件头骨的产地和层位精确标定在地图上,可是一切的分析数据都标明这件头骨大约产自哈尔滨区域距今13.8万年——30.9万年的陆相地层。”

shao qingfeng, another team member and a geochemist from nanjing normal university, said the team was very confident that the skull is more than 146,000 years old.

另一位团队成员、来自南京师范大学地化专家邵庆丰标明,他们如今非常深信,这件头骨化石距今至稀有14.6万年的前史。

“the harbin cranium is huge, showing either the largest or second-largest values for many measurements in our comparative fossil database, and its brain size, at 1,420 milliliters, matches that of modern humans,” chris stringer, a paleoanthropologist from the natural history museum in london who was also a member of the team, said in the media release.

来自伦敦天然前史博物馆的古人类学家、团队主研成员克里斯·斯特林格标明:“哈尔滨发现的古人类头骨可以说是无量的。在咱们比照的数据库中,这件古人类头骨的许多测量值都是出类拔萃大的,脑容量约为1420毫升,堪比现代人类的脑容量。”

stringer said it is widely believed that the neanderthals formed a sister group of the homo sapiens lineage. “but our analysis suggests that the harbin cranium and some other middle pleistocene human fossils from china form a third east asian?lineage, which is actually closer to h. sapiens than the neanderthals are,” he said.

斯特林格说:“以往盛行的观念认为尼安德特人是智人支系的姊妹群,可是咱们的分析标明哈尔滨发现的古人类头骨化石和我国其他区域发现的一些古人类化石构成一个日子于东亚区域的第三支系,这个支系与智人的亲缘联络要比尼安德特人与智人的联络近得多。”

the excellent preservation of the harbin skull throws new light on the evolution of the genus homo, he added.

他弥补道,哈尔滨发现的古人类头骨的无缺保存为人类进化供给了新的思路。
