Neandertal Diners Had Side of Veggies

尼安德谷人也有“吃素的”

&g.b(xTDE_GcAU&Sd^

When it comes to Neandertal diets, the consensus has been: they ate meat. Lots of meat.But now it looks like Neandertals chomped on a fair amount of veggies, too.Researchers have had a tough time discerning the Neandertals’diet. They evaluated carbon and nitrogen isotopes in bones, but those only correspond to some general kinds of proteins. Even plant remains in Neandertal teeth could have gotten there because a tasty animal carcass itself contained traces of a last vegetarian meal.
每次提到尼安德河谷人,人们总会一致认为他们是疯狂的肉食主义者2Ri6Ae9F@~|[t8。但是,现在有证据显示尼安德河谷人也会进食大量素食32mfPwIdCL6]。为了研究尼安德河谷人的饮食,科学家们可谓是煞费苦心1YRHIK+i!J1v9_PO|4。他们检测了尼安德河谷人骨头中碳元素和氮元素的数量,但仅与一些普通种类的蛋白质相对应VSVL.bxuf8yBk=@x*,。甚至连在粘在尼安德河谷人的牙齿上的菜叶中也可以检测到这些物质,因为一具美味的动物尸体在生前也吃过素食.b1Eq*cnc.+3~

So the researchers relied on foolproof evidencethey studied Neandertal fecal remains from a site in southern Spain called El Salt. Neandertals made it their home about 50,000 years ago.The researchers analyzed the samples for chemical compounds that can only result from metabolizing cholesterol from meat or from metabolizing plants. All five samples showed evidence of meat consumption. But two revealed the digestion of plants.Meaning that Neandertals did try vegetation, likely tubers and nuts.
研究员们只好寄希望于最简单不过的证据,那就是尼安德河河谷人的粪便hYn;yL*Jo^K=TlON(!B8。5万年以前,尼安德谷人在西班牙南部的一个名叫E1 Salt的地方栖息居住过,研究人员们就是在那里找到并研究的尼安德河谷人的粪便]GZQ8n2FFdy@h6GM。研究人员试图通过研究粪便的样本找到只能通过分解胆固醇或者只能通过消化非肉类食物而获得的化学物质7u13k6^BP--Z%。结果是,五组粪便中显示了肉的分解物,而另外两组则显示植物的消化#u8(IOr6~N&@^ag2YF。这表明,尼安德河谷人的确尝试过素食,比如块茎类植物和坚果tt-4g&s(_mpajLbL
The study is in the journal PLoS ONE.

In the hopes that any remaining poop may deliver an ancestral-diet scoop.
