Scientists discover the real reason why people actually fall in love

It’s been the subject of thousands of poems, songs and films – but until now, scientists haven’t fully understood why love exists at all.

Specifically, scientists haven’t fully understood why we evolved this behaviour in the first place.

But a new study of the Hadza people in Tanzania might offer a clue – as among the hunter-gatherers, highly ‘committed’ couples have the most children.

The tribe, who live as people did 10,000 years ago, are studied as a way to look into humanity’s past.

In modern societies, technologies such as contraception disrupt the link between levels of commitment and reproduction.

The researchers say, ‘We found that commitment and reproductive success were positively and consistently related in both sexes.’

The authors said, ‘Our study may shed new light on the meaning of love in humans’ evolutionary past, especially in traditional hunter-gatherer societies in which individuals, not their parents, were responsible for partner choice.’
