This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Chickens evolved from whatever came before chickens through small changes in their, and see from this description that the egg came first. Prior to that first true chicken zygote, there were only animals similar to a chicken but not exactly a chicken. So, all this means that there were eggs before there were chickens, but these eggs weren't really chicken eggs until there were chickens to lay them. What came first - the chicken or the egg? what answer that came first to your mind when somebody ask this question, please vote ! chicken..:0 egg......:1
Isn't the question more precisely Which came first? The chicken or the chicken egg? Otherwise it is quite clear that there were non-chicken eggs before there were chickens. I would have to say though that the chicken egg came before the chicken. Assume that there was some chicken-precursor that eventually evolved into what today is a chicken. At some point a chicken-precursor had evolved close enough to a chicken to lay an egg that contained a chicken as opposed to a chicken-precursor. Even if we take adaptations into consideration, the egg still came before the chicken. We can assume that there were some chicken-precursors, that developed traits which made their survival more likely than the average chicken-precursor. Evolution favors these traits and over time the chicken traits would have become more dominant until eventually all we are left with is chickens. These adaptations do not just one day appear in full-grown chicken-precursors, they appear as genetic traits in the fetus and are with the chicken-precursor from birth. So which came first? The chicken-precursor or the chicken-precursor egg?
I would have to agree with Jason. suppose one of his chicken-precursors laid an egg with a baby chicken-precursor in it. It would then have to be born as a chicken-precursor not a chicken and barring some sort of alien genetic intervention it would have to remain a chicken-precursor for its entire life. It cant hatch as a chicken-precursor then spontaneously evolve into a chicken. The first chicken egg would have been a mutation laid by a chicken-precursor. Again, this is removing the possibility of some alien Col. Sanders trying to corner the earth chicken-precursor market. Dave
Gee, I am still trying to figure out how those one celled asexually dividing creatures - you know the ones that spontaneously divide and become two creatures - how could they POSSIBLY evolve into something that required two to tango? I am convinced that if we find the answer to this question, then we will begin to understand which came first - the chicken or the egg. Because of course THEY are the precursor to the precursor to the etc. precursor of the chicken.
Isn't the question more precisely Which came first? The chicken or the chicken egg? What's a "chicken egg"? Is it an egg which contains a chicken? Or an egg laid by a chicken? Not quite the same thing. The sequence would be:
egg containing chicken, from proto-chicken
egg laid by chicken (containing another chicken)
So depending on how you define a "chicken egg", either answer is possible. Of course, this assumes that chickenhood is a binary property. I'm inclined to think the whole process was much more gradual, to the extent that it's unlikely that, if a group of zoologists time-traveled back to when the first recognizable chickens were appearing, they would have had an awfully hard time agreeing on which one was the first "true chicken". Or which was the first "true chicken egg". Then again, maybe they'd find a group of proto-chickens gathered around a big black monolith. Perhaps one of the chickens could suddenly pick up a bone in its beak and use it to peck the skulls of the lesser proto-chickens. Then we'd have a strong, clear contender for the title of "first chicken". (I don't suppose anyone else remembers Ray Stevens' "Thus Cacked Henrietta"? Pity...)
