Science Saturday I: Chicken or Egg Answered?

An expert panel made up of a British philosopher, geneticist and chicken farmer has finally answered which came first, the chicken or the egg.

They say that it's the egg.

Explains philosopher David Papineau at King's College in London:

I would argue it's a chicken egg if it has a chicken in it. If a kangaroo laid an egg from which an ostrich hatched, that would surely be an ostrich egg, not a kangaroo egg. By this reasoning, the first chicken did indeed come from a chicken egg, even though that egg didn't come from chickens.
