Learn about this Garden Talk

In order to survive, humans have to exist within a hierarchy, compete for resources and cooperate between the sexes - the most complex cooperation of all. Ideally, we would be solitary. So what has evolution come up with to make sure we start and then invest in our survival-critical relationships? Love.

We are the most cooperative species on the planet in terms of the number of ties we have, the context of those ties and their enduring nature. We need to cooperate to subsist, to raise our children and to learn, but cooperation is costly and stressful - possibly even life-threatening - because people lie, cheat and steal.

Evolutionary anthropologist Dr. Anna Machin is fascinated by what makes humans behave the way they do, and uses a full range of disciplines and techniques – from genetic analysis to experimental psychology - to find out. Anna joins us in The Garden to explore the origins of love.
