Why do we love who we love? Why do we stay in unfulfilling relationships, or stray from rewarding ones? Why do some couples crash and burn while others stay madly in love?

In The Intimate Animal, Dr Justin Garcia - one of the world’s leading experts on the science of love and sex – reveals that the answer to these questions lies in our evolution. We are biologically wired to connect with each other, yet our inner intimate animal is often at odds with the way we live now.

Dr Garcia explains the multiplicity of human sexual and romantic behaviour using cutting-edge research from his team of researchers at the world-leading Kinsey Institute, including:

- Why we have evolved to live and die for love
- Why searching for ‘the one’ is futile
- Why we are wired for 'social monogamy’ but not necessarily ‘sexual monogamy’
- Why some people are more likely to cheat

With practical tips on love and lust – the two biological systems often in painful conflict – The Intimate Animal is the essential, research-backed guide for anyone who wants to forge deeper, more intimate connections in these disconnected times.
