Life is just a dream! That is why folk that do not understand this can never solve the chicken and egg scenario.
The 'chicken/egg question is one of simple middle school biology;
Which came first, the chicken or the egg?
In nature, living things evolve through changes in their DNA. In an animal like a chicken, DNA from a male sperm cell and a female ovum meet and
combine to form a zygote -- the first cell of a new baby chicken. This first cell divides innumerable times to form all of the cells of the complete
animal. In any animal, every cell contains exactly the same DNA, and that DNA comes from the zygote.
Chickens evolved from non-chickens through small changes caused by the mixing of male and female DNA or by mutations to the DNA that produced the
zygote. These changes and mutations only have an effect at the point where a new zygote is created. That is, two non-chickens mated and the DNA in
their new zygote contained the mutation(s) that produced the first true chicken. That one zygote cell divided to produce the first true chicken.
Prior to that first true chicken zygote, there were only non-chickens. The zygote cell is the only place where DNA mutations could produce a new
animal, and the zygote cell is housed in the chicken's egg.
So, the egg must have come first.
Chicken and egg debate unscrambled
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
Professor John Brookfield, a specialist in evolutionary genetics at the University of Nottingham, told the UK Press Association the pecking order was
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
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
