Seventy thousand years ago, our human ancestors were insignificant animals, busy surviving and coexisting with other animals in a corner of Africa whose impact on the planet was no more than that of a jellyfish or a woodpecker, says historian Yuval Noah Har­ari, aut­hor of Sapiens: A Brief History of Humankind. Which, of course, was a good thing. In a cartoonish idealisation, they were probably having a good time, in a proto-hippie sort of way, singing around campfires in the jungle, keeping an eye out for flashing sabreteeth, causing no harm.

A touch of gallows humour is not out of place as we scan the scene now. Some scientists say a sixth mass extinction may be under way as you read this. The known species loss over these recent millennia, a blip in geological time, indicates that we may well have initiated, through our good offices, an event analogous in scale of calamity to the five such previous INS­tances, spread out over 540 million years. When, in geologically short intervals, the Earth lost two-thirds of its species.
