在17萬(wàn)年前的洞穴中發(fā)現(xiàn)的古代烤根菜

Cavemen did not eat nearly as much meat as we thought, according to the recent discovery of ancient root vegetables.

根據(jù)最近發(fā)現(xiàn)的古代根類(lèi)蔬菜，穴居人吃的肉幾乎沒(méi)有我們想象的那么多。

Scientists have dated charred plant stems found in a South African cave to be nearly 170,000 years old, a study published Friday in the journal Science finds.

周五發(fā)表在《科學(xué)》(Science)雜志上的一項(xiàng)研究發(fā)現(xiàn)，科學(xué)家們?cè)谀戏且粋€(gè)洞穴中發(fā)現(xiàn)的燒焦的植物莖干的年代接近17萬(wàn)年。

Lead author Lyn Wadley, of the University of the Witwatersrand in South Africa, and her team discovered a charcoal pile within the rock shelter. After years of microscopic analysis, they confirmed that its ash layer contained hundreds of plants.

研究報(bào)告的第一作者、南非威特沃特斯蘭德大學(xué)的琳恩·瓦德利和她的研究小組在巖石掩體內(nèi)發(fā)現(xiàn)了一堆木炭。經(jīng)過(guò)多年的顯微分析，他們證實(shí)了火山灰層中含有數(shù)百種植物。

The discovery represents rare proof of prehistoric humans’ consumption of carbohydrate-rich roasted veggies. It also shows that early people were actually healthy in their eating habits.

這一發(fā)現(xiàn)為史前人類(lèi)食用富含碳水化合物的烤蔬菜提供了罕見(jiàn)的證據(jù)。研究還表明，早期人們的飲食習(xí)慣實(shí)際上是健康的。

“I think people were eating a very balanced diet, a combination of carbohydrates and proteins,” Wadley tells the New Scientist. Despite the common notion that Stone Age people ate a lot of meat, Wadley says her findings help prove that they actually had a veggie-rich diet.

“我認(rèn)為人們的飲食非常均衡，碳水化合物和蛋白質(zhì)的結(jié)合，”Wadley告訴《新科學(xué)家》雜志。盡管人們普遍認(rèn)為石器時(shí)代的人吃很多肉，Wadley說(shuō)她的發(fā)現(xiàn)有助于證明他們實(shí)際上有一個(gè)富含蔬菜的飲食。
