Humans likely developed large and powerful brains, researchers said Monday, with the help of what is today the simplest of snacks: fruit. Eating fruit was a key step up from the most basic of foodstuffs, such as leaves, and provided the energy needed to grow bulkier brains, the scientists argued. 研究人员于周一表示：有了当今时代最简单零食--水果的帮助，人类有可能发育出更大、更强的大脑。科学家说，吃水果是从吃最基本的食物（如叶子）中迈出的重要一步，并且还提供了发育大脑所需的能量。 "That's how we got these crazy huge brains," said the study's corresponding author Alex Decasien, a researcher at New York University. "We have blown up the quality of our food that we are eating." The study published in Nature Ecology & Evolution looked at the staple foods of over 140 species of primates, and assumed their diets haven't changed much over the course of recent evolution. "因此我们的大脑才如此疯狂的巨大，"纽约大学的研究员兼本研究的通讯作者Alex Decasien说道。"我们已经放大了所吃食物的质量。"该研究刊登在《自然生态与进化》期刊上，研究了140多种灵长类动物的主食，并假设在近期的进化过程中，它们的饮食变化不大。 |
