Three important revolutions shaped the course of history: the Cognitive Revolution kick-started history about 70,000 years ago. The Agricultural Revolution sped it up about 12,000 years ago. The Scientific Revolution, which got under way only 500 years ago, may well end history and start something completely different.

从大爆炸写到人类和历史的出现，列出了本书的线索——人类社会的三大革命：认知革命、农业革命、科技革命。接着从生物学分类的角度阐述了：人类并没有他们自己想象的那样特别，而只是一种灵长目动物。

有趣的观点和疑问
Most mammals emerge from the womb like glazed earthenware emerging from a kiln – any attempt at remoulding will scratch or break them. Humans emerge from the womb like molten glass from a furnace. They can be spun, stretched and shaped with a surprising degree of freedom.This is why today we can educate our children to become Christian or Buddhist, capitalist or socialist, warlike or peace-loving.
概述：人类初生的脆弱给了人类幼崽更多教育的机会，使得人类智力得以发展。
问题：只有人类幼崽初生格外脆弱吗？其他动物也会教育幼崽，只是不如我们的教育内容那么繁杂。也可以是因为人类本身拥有更高的智能，所以才能在拥有漫长成长期的情况下，依然通过了自然选择。而不是因为人类有更长的成长期，所以我们才能获得更高的智力。这段缺乏充分的论证，感觉只是作者在开脑洞啊。
Other animals at the top of the pyramid, such as lions and sharks, evolved into that position very gradually, over millions of years. This enabled the ecosystem to develop checks and balances that prevent lions and sharks from wreaking too much havoc. ... In contrast, humankind ascended to the top so quickly that the ecosystem was not given time to adjust. Moreover, humans themselves failed to adjust. Most top predators of the planet are majestic creatures. Millions of years of dominion have filled them with self-confidence. Sapiens, by contrast is more like a banana republic dictator. Having so recently been one of the underdogs of the savannah, we are full of fears and anxieties over our position, which makes us doubly cruel and dangerous. Many historical calamities, from deadly wars to ecological catastrophes, have resulted from this over-hasty jump
概述：狮子、鲨鱼之类的动物在漫长的演化中逐渐成为食物链顶端的动物，生态系统在这一过程中创造出了与之制衡的力量，防止这些动物造成过度的破坏。但人类是突然进驻食物链顶端的，因此生态系统没有足够的时间自我调整，人类自身也难以适应这一变化。顶级捕食者拥有生而为王的宏大气度，而人类却缺乏足够的信心和安定感，这便塑造了人类格外残忍的天性。
问题：很有意思的观点，但是缺乏根据，难以令人信服。依然是脑洞大开的产物。
It turned out that 1–4 per cent of the unique human DNA of modern populations in the Middle East and Europe is Neanderthal DNA. That’s not a huge amount, but it’s signiɹcant. A second shock came several months later, when DNA extracted from the fossilised ɹnger from Denisova was mapped. The results proved that up to 6 per cent of the unique human DNA of modern Melanesians and Aboriginal Australians is Denisovan DNA.
..., yet it appears it was still just possible, on rare occasions, for a Sapiens and a Neanderthal to produce a fertile offspring. So the populations did not merge, but a few lucky Neanderthal genes did hitch a ride on the Sapiens Express. It is unsettling – and perhaps thrilling – to think that we Sapiens could at one time have sex with an animal from a different species, and produce children together
两个观点：现代中东人与Neanderthal有1-4%的人类基因是一样的，如果这一数据属实，早期Sapiens和Neanderthals可能交配、生产过。当时两种人类可能即将产生生殖隔离，但尚未变成真正的两个种族，所以少量的Neanderthals和Sapiens交配繁衍，在基因上留下了这些痕迹。这种人类曾经与其他动物繁衍的想法十分惊悚\(≧≦)/。
问题：一. 证据部分似乎缺少了一个关键性的数据：当时的Sapien和Neanderthal的人类DNA有多少相同？这些相同的DNA中有多少是那1-4%相同的DNA中的？没有这个数据我不知道作者怎样推出的结论。二. 如果sapien和其他homo species能够繁衍，并且传承DNA，那么说明sapien和那几个homo species没有产生生殖隔离，还是是同个种族啊。既然大家都是同个种族，为什么还算和其他动物交配呢呢呢？以我高中水平的生物知识，实在不能理解啊啊啊？？？
