The birds have a "fossilised" version of the key molecule responsible for severe allergic reactions in humans.

The molecule in birds, called IgY, appears to be an ancient forerunner of a similar human molecule called IgE - one of the culprits when the immune system goes into overdrive during asthma attacks or anaphylactic shock.

Dr Alex Taylor, one of the researchers, said: "This molecule is like a living fossil - finding out that it has an ancient past is like turning up a coelacanth in your garden pond.

He said: "If we could find a way to unbind IgE from white blood cells, then a lot of these allergic reactions could be stopped before they start.
