They say, David Attenborough reports, that we share more of our genes with chimpanzees than any other species alive today.

It was this proximity of Homo Sapiens to the chimpanzee which motivated him even more to film behaviour never before seen.

It had been known for some time that chimps hunt monkeys for meat, but it would be a first to film it for TV audiences.

To film such a hunt required days of waiting and tracking a troop through the Equatorial African forest - and when the hunt came and was over it changed Sir David Attenborough's view of chimps and their importance to us, forever.

Written and presented by David Attenborough.
