I reported recently that scientists claimed to have found a definitive conclusion to the “chicken or egg” conundrum, but it seems neither was in fact first – it was a duck.
Five beautifully preserved headless fossil skeletons discovered in China suggest modern birds evolved from aquatic duck-like ancestors. The creatures, which shared the planet with dinosaurs 110m years ago, are the oldest modern bird fossils ever found.
The story doesn’t, however, explain where the heads went – so perhaps before the ducks there was a fox?
