Good reasons to be a naked mole rat

If I were a bird, I think that I would like to be a great-crested grebe. Smart looking fellow and spends a good deal of time underwater as well as above it – which must be interesting. Recently, Margaret and I went on holiday from our base in Spain. I know what you are thinking, you’re thinking that we are on holiday whilst we are in Spain anyway, but that’s not true. There is work to do on the huerto and the house: crops to plant and weed, olive trees to trim and hoe, irrigation to sort out and things to mend about the house. Anyway, our holiday started in Daroka, Aragon a unique town nestling in a narrow valley the ridges of each side being capped with ancient walls interspersed with Mudejar towers and reminding me of the crests on the backs of certain lizards and Margaret of the Great Wall of China.

Next day we moved on to visit Gayocanta Laguna, an interior salt lake, in the hope of seeing water birds, maybe even a crested grebe. But, alas, the extensive salt lake was parched, it was in fact salt – so no water birds at all. We moved on spending the night in Utrillas, an old mining town, where we dined on yet another ‘menu del dia’: these are three course meals with bread wine and coffee for a fixed cost, in this case just sixteen Euros apiece. With beer before and wine during our subject range became extensive, even incorporating the vexed question of consciousness. Margaret argued strongly with me that consciousness could not simply be something that evolved by Darwinian survival, there must be something else - though she did not know what that might be.

For me that debate surfaced my usual question: do other animals have consciousness. I believe they do to some extent and that extent may well evolve with geological time. A dog, on whose face a disc has been painted will, it is claimed, try to remove it when passing a mirror. Cats train their owners to provide them with food in trade for rationed affection. Chimps like a good joke and grebes are very much aware that other grebes may steal their dinner. Naked mole rats meanwhile may have a group consciousness. These little chaps are certainly not smart looking fellows, but you might want to be one. Take longevity for example other animals of their size rarely survive for a year or so whereas the naked mole rat clocks up over thirty! Mole rats are rarely lonely: they live below ground in tribes of as many as two hundred in service to their queen; a bit like ants. It gets a bit crowded down there so the good old mole rat has developed a plant like ability to live without oxygen - for up to five hours! They are pretty much immune to pain and to cancer and have no worries about having their coats stolen to make into trousers or being asked difficult questions in referenda.

So there you have it: either a short life on and below the watery waves as a grebe or a long one in the warm - dark burrows of a naked mole rat nest. You have consciousness, make your choice.
