"Time for the younger rival to make an appearance," I murmured to Jessie. (Jessie ignores the TV most of the time, but she'll sit on my lap for wildlife programmes and watch intently.)
Sure enough, the next shot showed a young male giraffe shimmering towards us through the heat. A mighty battle for mating rights ensued.
How did I know that he would be making an imminent appearance? That's what Jessie would have asked if she'd been able - but what should I have replied? Is it that this is simply what nature is like - a struggle to spread one's genes about? Or is it that BBC wildlife documentaries have a limited set of storylines, and recycle them over and over again? What is certain is that I've seen the selfsame scenario played out a hundred times, by everything from bull seals to iguanadons. Someone's imagination seems a bit limited, but is it God's or David Attenborough's?
Is there, in fact, a difference?
