Which came first: the chicken or the egg?
Since the beginnings people have had this dilemma: “Which came first the chicken or the egg?” mathematicians, theologians, scientists, philosophers andnormal people argue about it, but there has never been an answer, and people will die to know the answer.
It all started back with Aristotle he was puzzled by the idea that there could be a first birdor egg and concluded that both the bird and egg must have always existed.
There are several theories that explain the dilemma:
Mathematical theory: Thurman and Fisher examined US egg production andchicken population from 1930 to 1983. By looking at the annual number of eggs produced, and comparing it with the total number of chickens, Thurman and Fisher wanted to see if the chicken populationpredicted the number of eggs laid, or if the number of eggs predicted the chicken population, or both. It was found that information present in the egg time series predicted the number of chickens.Thurman and Fisher concluded that the egg came first.
Evolution theory: Darwin's theory of evolution states that species change over time via mutation. A mutation must have taken place within an egg suchthat an animal similar to a chicken, but not a chicken, laid the first chicken egg. In this light, both the egg and the chicken evolved simultaneously from birds that were not chickens and did notlay chicken eggs but gradually became more and more like chickens over time.
The modern chicken was believed to have descended from another closely related species of birds, the red junglefowl, butrecently discovered genetic evidence suggests that the modern domestic chicken is a descendant of both the red junglefowl and the grey junglefowl. It concluded that the chicken egg came before thechicken.
Theology theory: Judeo-Christian writings indicate God's creation of birds along with the rest of the universe in the Genesis. The Judeo-Christian story of creation describes God creating birds,...
