What Gave Some Primates Bigger Brains? A Fruit-Filled Diet
The researchers analyzed the brain sizes and diets of over 140 primate
species spanning apes, monkeys, lemurs and lorises and found that those who
munched on fruit instead of leaves had 25 percent more brain tissue, even
when controlling for body size and species relatedness.
...
The findings challenge a long-held scientific hypothesis that the size of
social groups among primates is the biggest determinant of brain size. The
bigger the social group, the more complex the social interactions, leading
to the evolution of larger brains with more computing power, the theory
suggests.
...
Overall, diet appeared to be a more consistent predictor of brain size for a
species than social complexity — brain sized increased with fruit eating
more consistently than with greater number of social connections.

我觉得打工仔总比挖沙仔好一些，挖沙仔比炮灰仔还是要好那么一点点。

子子孙孙扎在数理化里继续陶醉？

发帖数: 1034 | 7 Key paragraph:
"If you are foraging on harder-to-access food, like fruit instead of leaves,
then you need to have all the cognitive strategies to deal with that," says
Alex DeCasien, a doctoral candidate at New York University and lead-author
on the study. Fruit can vary from season to season, be tucked away in hard-
to-reach nooks, and require skill and strength to crack into, smarter
primates could be more apt to scope it out and reap its nutritious rewards.
"All of that is so much more complicated than just grabbing a leaf and
eating it," she says. And so, a diet of fruit may in turn have led to the
evolution of the bigger brains over generations, she adds.
获取食物过程的复杂性促进了大脑的进化。没提碳水化合物。
楼主是来搞笑的，作为学习型的代表人物，他肯定仔细阅读学习了文章，看了这一段。
希望大家不要误会他。。
更不要轻信他的搞笑结论，给自己孩子猛灌米饭。吃出肥胖症糖尿病来，他又不负责。 |

发帖数: 1034 | 8 从自然科学的角度来说，这种研究并不科学。
观察-提出假设-设计实验验证，缺少了最后一环。
水平停留在亚里士多得时代，离伽利略的实验验证还有很长的距离。
当然，对于进化研究，做实验难度忒大。。 |

发帖数: 1034 | 9 从社会学的角度来说，这个研究是个“大毒草“。
研究相似物种（特别是灵长目）之间的大脑体积差异，很容易让人联想到人种之间的智
力差异。
比如，有好事之徒会想，农耕和渔猎民族的脑容量会不会比守在面包树旁的民族智力高
些呢？
应该以“政治正确”之名予以封杀。 |

孩子喜欢自己去创造发现，不能一概而论吧。
健康开心有责任心就行了，对自己负责，对社会负责
