The ancestral apes already had large and high-quality brains.They had good eyes and efficient grasping hands.They inevitably had some degree of social organization.With strong pressure on them to increase their preykilling power,vital changes began to take place.They became more upright,and were faster,better runners.Their hands became strong,efficient weapon holders.Their brains became more complex,and developed into brighter,quicker decision-makers.But there developments did not follow one another in a major,set sequence;minute advances being made first in one quality and then in another,each urged the other on.A hunting ape,a killer ape,was in the making.
祖先猿已经有大型高品质的大脑。他们有很好的眼睛和高效紧握的手。他们必然有某种程度的社会组织。他们强大压力的增加preykilling功率，至关重要的变化开始发生。他们变得更加直立，，更快，更好的选手。双手变得强大，有效武器持有人。他们的大脑变得更加复杂，并发展成光明，更快的decision-makers.but发展并不是沿着另一个一个专业，集序列；刻的进展是第一质量，然后在另一个，每个敦促的其他上。一个狩猎猿，猿的杀手，是制作。
