Legitimate question

From our UK edition

My father believed – wrongly – that I wasn’t his child. If only there had been DNA tests to reassure him In this magazine two weeks ago, Melanie McDonagh suggested that DNA testing is tough on children whose apparent fathers turn out not to be anything of the kind. In particular, she had sympathy for the child whose TV presenter ‘father’ discovered that for years he had been paying child support for somebody else’s offspring. No doubt she has a point, but what of the children whose true fathers doubt their paternity? For me, DNA testing would have been a blessing. My father doubted I was his child, though I didn’t know it. I just knew that he didn’t seem to care for me very much. ‘The cuckoo in the nest’ is what he called me.

Are octopuses just like us?

From our UK edition

The publicity frenzy over Paul the octopus, who accurately predicted the results of the World Cup by opening boxes labelled with team colours, has concealed something much more interesting than his apparent psychic powers. Here is an animal with a third of his nervous system outside his brain and no central spinal column who is nevertheless able to open man-made jars and boxes. This ‘lower form of life’, as we might once have called an invertebrate, can use tools, navigate mazes, recognise the humans that feed him, and make use of landmarks in planning a route. Scientific interest in octopus intelligence is part of a quiet revolution in animal behaviour science.
