Evolution: the paradox of Homo floresiensis
Evolution of brain volume in homininaee
There has been a gradual increase in brain volume as we progressed along the
Human timeline of evolution (see Homininae), starting from about 600 cm3 in
Homo habilis up to 1500 cm3 in Homo sapiens neanderthalensis. Thus, in
general there's a correlation between brain volume and intelligence. However

发帖数: 16384 | 8 物种演化的基本单位是基因，而不是具体的个体，个体只是多个基因的打包，所以祖先
并不必然收敛到某一两个个体。
假设人与猿共同的基因是y1,y2,y3...
人与猿不同的基因是x1,x2,x3...
1.也许每个x基因，都来自于一个不同的个体。这些突变出x的个体，也许是同一个群落
的，也许是同时代不同群落的后来相遇的，也许分布在不同的历史时期。
2.之所以为人，是因为有x基因，但是首先还得有y基因。提供了x的是祖先，但是提供了
没有变异的y基因的一样也是不可缺少的祖先。
突变出x的个体，需要与同时代其他没有发生突变的个体交配，将x传播出去，所以这些
没有发生突变的个体，同样也是祖先。

发帖数: 27294 | 10 我们祖先变直立人的时候就不吃大量水果了。我们在脱离猿类（Ape Line）之后，变成
hominid的时候，就已经是完全肉食动物了。
基因每１０－５０万年会大变迁。环境很恶劣的话，几十代也可以。
所以４００万年前吃什么，不决定我们应该吃什么；同样几千年农耕以后吃什么，也不
决定我们应该吃什么。

＂The Australopithecines were not browsers and fruit-eaters with very high
intakes of vitamin C; rather they were scavengers of kills made by other
animals.＂
---直立人不是吃含大量VC的水果的采集者，而是吃大量肉食的猎捕者。
大量食红肉，才让人类大脑有大发展，才促进了工具产生：最早工具是猎捕工具。 |

This transformation will become Zarathustra's answer to the fears and

南方古猿的平均脑容量大概是400~500cc, 比现代人类的1350cc的小很多，

一个有意思的问题就是这些南方古猿会不会制造/使用工具？

和不少人想象的可能不同，其实大部分哺乳动物和鸟类在经过训练
