Gorillas, with 97 per cent of our DNA, have always shown close similarity to humans through their expression of intense emotion.

For Kesho and Alf, who grew up together at Dublin Zoo and were reunited in Longleat Safari Park in Wiltshire (they were separated when Kesho was sent to London Zoo to breed), those feelings were patently much more than friendship — this was the bond of brotherhood.
