How Did We Get To Be So Different?

How is it we humans only arrived after 99.995% of the time there's been life on earth - and yet we're now so dominant? If mutations take generations to have an effect, how did we manage to change so completely in just a blink in time? And why were our rulers and societies always so horrible - yet we endlessly put up with them?Book One of The Secrets of Life quartet began the long narrative of existence by showing how the forces that Big Bang unleashed drove the Earth's evolutionary developments, and how it after 3.8 billion years of life and the extinction of many billions of species, our obscure forest-dwelling ancestors emerged in East Africa.

Yet what, Book Two asks, were the steps that led to us humans becoming so totally different to anything that had appeared before?

If we really were just another kind of animal off the production line of life, then what were the revolutions that turbo-charged our unique abilities?How did we evolve so that we could alter ourselves in an instant, and avoid being stuck in an evolutionary niche like every other organism?

How did we manage to create the intelligence and insights that allowed us to make our own decisions in life? And where did the free will come from that would let us override the drives of our animal pasts?

We alone of all the world's species have ever been able to predict the future, and then change our behaviour so that it suited our ambitions.

But how did we grow our brains and imaginations so greatly that we could achieve this? And only we have evolved the capacity to reject the genetic instructions that shaped us.

But why do we think this helps - and how has it affected our lives?

Now, using the same easy-going conversational style of the other books in the series, O'Connor answers these and other questions to explain how we evolved to break away from everything that had existed before us. And yet why the effects of our heritage so often still emerge in how we exist.
