Sir David, whose new show concentrates on the ascent of man, said he believed humans had now stopped evolving in physical terms, after developing means to keep even the weakest of the species alive.

Saying we are now able to rear up to 99 per cent of our babies, he added people were no longer subject to Darwinian theories natural selection.

Instead, he proposed, humans would continue to develop in a cultural sense; inheriting knowledge from previous generations and building upon it.

In an interview with the Radio Times this week, Sir David said: “I think that we’ve stopped evolving.

“Because if natural selection, as proposed by Darwin, is the main mechanism of evolution – there may be other things, but it does look as though that’s the case – then we’ve stopped natural selection.

“We stopped natural selection as soon as we started being able to rear 95–99 per cent of our babies that are born.

“We are the only species to have put a halt to natural selection, of its own free will, as it were.”

Sir David, who will present Rise of Animals on BBC2, added: “Stopping natural selection is not as important, or as depressing, as it might sound – because our evolutionary process is now cultural.

“Humans have a great cultural inheritance as well as a physical, genetic inheritance – we can inherit a knowledge of computers or television, electronics, aeroplanes and so on.

“Each generation has got all these books that tell them these things, so our cultural evolution is proceeding with extraordinary swiftness.”

He also insisted he was grateful to live in the modern day, saying that things were likely to get worse with future generations looking back “at a world that was less crowded, full of natural wonders, and healthier.”
