Which came first -- the chicken or the egg?

Which came first — the chicken or the egg?

The question has a reputation for being difficult, perhaps even impossible, to answer. Philosophers treat it as a conundrum. But in the hands of an experimental scientist, the question is simple and straightforward, and the answer is easily obtained.

I doubt that I am the first to solve the chicken-and-egg problem, but a search of the scientific literature turned up surprisingly few accounts — none, in fact — of previous work. Here, then, is an account of my work on what turns out to be a trivial question.

How the Problem was Solved

Which came first — the chicken of the egg? I tackled the question experimentally, using a chicken, an egg, and the United States Postal Service (USPS).

I mailed the chicken and the egg, each in its own separate packaging, and kept careful track of when each shipment was sent from a post office in Cambridge, Massachusetts, and when it subsequently arrived at its intended destination in New York City.

Details of this experiment are here.
