How much can we know about the world? In this audiobook physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing he reaches a provocative conclusion: Science, like religion, is fundamentally limited as a tool for understanding the world. As science and its philosophical interpretations advance, we face the unsettling recognition of how much we don't know.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

In How We Do It, primatologist Robert Martin draws on 40 years of research to locate the roots of everything from our sex cells to the way we care for newborns. He examines the procreative history of humans as well as that of our primate kin to reveal what's really natural when it comes to making and raising babies, and distinguish which behaviors we ought to continue - and which we should not. Although it's not realistic to raise our children like our ancestors did, Martin’s investigation reveals surprising consequences of - and suggests ways to improve upon - the way we do things now.
