Hoooooooooooo boy. Don't ask me how I got onto this, but if you have a few people around you at work - or wherever you are (keep to yourself if you are in internet cafe), do a snap-poll. ONE ANSWER, FIRST ANSWER Only.
"Which came first - the Chicken or The Egg?" - that is your question.
I'll give you a few minutes. Go.
OK - Back?
I know the bloody answer, and most would say the egg - coz chickens had to come from somewhere. No? They said chicken? You have the right to flick their ear. How many answered chicken, coz you've got some flicking to do.
Simply put, you have to think about the time before the chicken.
A non-chicken has sex with another non-chicken, or frog or whatever. Inside the reproductive system of the female, mixing of male and female DNA or mutations of the DNA, produces the zygote. This z word you havent heard since 5th form is the key - and if you're religiously inclined, we will call it the "shake of god".
When the zygote mutates (dependant on its hosts DNA) a new species is formed. This mutation produces a new cell. Upon gods timetable, a gong is sounded, the cell splits into two and bada bing, bada boom you have Chicken.
Insummary, 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.
I'm here all week.
