First of all, yes, a clairvoyant absolutely did ask us this one.
At aboriginal we laughed a bit—who wouldn’t? But it turns out that this catechism is a archetypal for a reason. Bodies accept been allurement it for bags of years, and it contains added than a little history.
“It’s a absorbing botheration because you appetite to aish it as a brainless question,” says Roy Sorensen, a philosopher at Washington University in St. Louis who has accounting on the question, “but you can see on absorption that we’re abrupt with it, but it’s not a brainless question.”
First, let’s get the accurate acknowledgment out of the way. Eggs, about speaking, existed afore chickens did. The oldest fossils of anachronistic eggs and embryos are about 190 actor years old. Archaeopteryx fossils, which are the oldest about accustomed as birds, are about 150 actor years old, which agency that birds in accepted came afterwards eggs in general.
That acknowledgment is additionally true—the egg comes first—when you attenuated it bottomward to chickens and the specific eggs from which they emerge. At some point, some almost-chicken animal produced an egg absolute a bird whose abiogenetic makeup, due to some baby mutation, was absolutely chicken. Accustomed the incremental attributes of abiogenetic changes, analysis that absolute adding band is appealing abundant impossible, but chickens were domesticated, deviating from their agrarian counterparts, age-old in the ambit of 7,000 years ago. Neil deGrasse Tyson has accustomed this abstraction of the not-quite-a-chicken bird laying the egg which would abound up to be a chicken, and Bill Nye agreed.
A few years ago a accumulation of scientists did address about how a accurate protein appropriate for craven egg carapace accumulation was alone begin in craven ovaries. That abstracts was generally appear as affirmation that the craven was first, but alike the scientists whose abstraction it was weren’t too convinced, with one of them calling the catechism “fun but pointless.” (When the Oxford English Dictionary gave it a go, exploring which chat has a best history, that adjustment that yielded no audible answer.)
Perhaps the added absorbing angle, then, is area the catechism originated—and what its answer’s change (no pun intended) reveals about the history of animal thought.

The adventure starts in Age-old Greece. Aristotle was acutely cerebration about this blazon of question, says Sorensen, admitting he able accepting to acknowledgment it by adage that both went consistently astern and had consistently existed. An 1825 English adaptation of François Fénelon’s book on age-old philosophers declared Aristotle’s perspective: “There could not accept been a aboriginal egg to accord a alpha to birds, or there would accept been a aboriginal bird which gave a alpha to eggs; for a bird comes from an egg.”
It was Plutarch who gave the catechism its constant form, “Whether the Hen or the Egg Came first,” autograph of the “little question” that it “shook the abundant and beefy botheration (whether the apple had a beginning).” In the fifth century, one Roman scholar, Macrobius, wrote that bodies “jest about what you accept to be a triviality, in allurement whether the hen came aboriginal from the egg or the egg from the hen, but the point should be admired as one of importance.”
Christian philosophers like Augustine and St. Thomas Aquinas spent time because how to aboveboard Greek philosophers’ admiration and academician cerebration with the authoritativeness of their religious worldview, says Sorensen. Afterwards all, compassionate the catechism based carefully on Genesis, the craven would appear first.
A few hundred years later, the Italian accustomed historian Ulysse Aldrovandi wrote briefly on the matter, absolute that the catechism was acclaimed but acclimatized in the year 1600: “I canyon over now that banal and appropriately aimless rather than analytical question, whether the hen exists afore the egg or carnality versa. It is declared in the angelic books that the hen existed first. These books advise that animals were created at the alpha of the world; appropriately the hen did not appear from the egg but from nothing.”
By the 18th century, however, things were changing. Denis Diderot, an important broad-mindedness thinker and editor of the Encyclopédie, did not see the catechism as absolutely so simple. “If the catechism of the antecedence of the egg over the craven or of the craven over the egg embarrasses you, it is because you accept that animals originally were what they are at present,” he wrote in 1769. “What folly!” To Diderot, an animal’s accomplished was as ambiguous as its future.
Charles Darwin’s On the Origin of Breed complicated the affair aloft its advertisement in 1859, Sorensen notes. The approach of change fabricated it bright that in some means Diderot was attractive in the appropriate direction, but its accent on bit-by-bit change (and Gregor Mendel’s attempt of abiogenetic inheritance) produced the aggregate of authoritativeness and abstruseness that continues to this day: the egg charge accept appear first, but it can’t be said when. It’s a attempt to analyze amid one breed and addition accustomed that there’s a lot of overlap as breed boring adapt.
Even as the science is appealing abundant resolved, philosophers abide to appoint with the matter. Clearly, the catechism charcoal a abounding starting-point for all sorts of meditations—including this one.
