Egg came first, 'eggsperts' agree

LONDON, England - It's a question that has baffled scientists, academics and pub bores through the ages: What came first, the chicken or the egg? Now a team made up of a geneticist, philosopher and chicken farmer claim to have found an answer. It was the egg. Put simply, the reason is down to the fact that genetic material does not change during an animal's life. Therefore the first bird that evolved into what we would call a chicken(, probably in prehistoric times,) must have first existed as an embryo inside an egg. Professor (John) Brookfield, a specialist (in evolutionary genetics) at the University of Nottingham, told the UK Press Association the pecking order was clear. (The living organism inside the eggshell would have had the same DNA as the chicken it would develop into, he said. "Therefore, the first living thing which we could say unequivocally was a member of the species would be this first egg," he added. "So, I would conclude that the egg came first." The same conclusion was reached by his fellow "eggsperts" Professor David Papineau, of King's College London, and poultry farmer Charles Bourns. Mr Papineau, an expert in the philosophy of science, agreed that the first chicken came from an egg and that proves there were chicken eggs before chickens. He told PA people were mistaken if they argued that the mutant egg belonged to the "non-chicken" bird parents. "I would argue it is a chicken egg if it has a chicken in it," he said. "If a kangaroo laid an egg from which an ostrich hatched, that would surely be an ostrich egg, not a kangaroo egg." Bourns, chairman of trade body Great British Chicken, said he was also firmly in the pro-egg camp. He said: "Eggs were around long before the first chicken arrived. Of course, they may not have been chicken eggs as we see them today, but they were eggs." The debate, which may come as a relief to those with argumentative relatives, was organized by Disney to promote the release of the film "Chicken Little" on DVD.)

닭과 달걀 토론 해독
오랜 시간 동안 과학자, 학자 및 선술집의 해묵은 주제로 아주 난처하게 괴롭힌 건 "닭이 먼저냐, 달걀이 먼저냐"하는 이 한가지 질문이었습니다. 이제 유전학자들, 철학자들 그리고 양계업자들로 구성된 한 단체가 답을 구한 것 같다고 주장합니다. 바로 계란이었습니다. 간단히 말해 그 이유는 유전 형질이 동물의 일생 중 변하지 않는다는 사실에 귀착되기 때문이죠. 따라서 우리가 닭이라 부르는 새로 진화된 최초의 조류는 처음에 계란 속의 수정체로 존재했음에 틀림없습니다. Nottingham대학교의 전문의 Brookfield교수는 영국 언론협회와의 회견에서 순서가 분명했다고 말했습니다.
London ( 연합news) - ‘닭이 먼저냐, 달걀이 먼저냐’에 관한 해묵은 논쟁이 영국의 과학자와 철학자, 양계업자에 의해 달걀이 먼저인 것으로 결론이 났다고 영국 신문들이 26일 보도했다. 유전물질이 동물의 일생 동안 변하지 않기 때문에 닭으로 진화한 최초의 새도 원래는 알 속에서 배아 형태로 존재했어야 한다는 점이 핵심이라고 신문들은 전했다. John Brookfield(유전자학) Nottingham대 교수는 “바로 이런 이유로 알 속의 살아있는 기관과 닭의 DNA가 동일하다”면서 “따라서 최초의 생명체는 분명히 최초의 알이었으며 알이 먼저다”라고 말했다. David Papineau(과학철학) Kings대 교수도 “닭의 시조는 비록 다른 종의 새가 낳았더라도 알에서 출현했기 때문에 달걀로 부를 수 있다”고 주장했다.
