Chicken or Egg finally solved!!

'The chicken came first, not the egg', scientists prove
It’s an age-old puzzle that’s stumped generations of scientists.But now they believe they have cracked the conundrum of what came first: the chicken or the egg.
British researchers say the chicken must have come first as the formation of eggs is only possible thanks to a protein found in the chicken’s ovaries.
‘It had long been suspected that the egg came first but now we have the scientific proof that shows that in fact the chicken came first,’ said Dr Colin Freeman, from Sheffield University, who worked with counterparts at Warwick University.
‘The protein had been identified before and it was linked to egg formation but by examining it closely we have been able to see how it controls the process,’ he added.
The protein – called ovocledidin-17 (OC-17) – acts as a catalyst to speed up the development of the shell.
Scientists used a super computer called HECToR, based in Edinburgh, to ‘zoom in’ on the formation of an egg.
It showed OC-17 was crucial in kick-starting crystallisation – the early stages of forming a shell.
The protein coverts calcium carbonate into calcite crystals which makes up the egg shell, creating six grammes of shell every 24 hours.
Prof John Harding, also of Sheffield University, said the discovery could have other uses.
‘Understanding how chickens make shells is fascinating in itself but can also give clues towards designing new materials,’ he said.
Next challenge: Why did the chicken cross the road?

Why did the chicken cross the road.....?

I get it. The Chicken came first cuz he/she made the shell.
Where did she come from?

It was a 'she' I hope Dave...... or do we have another age old question?
-
okay. . .my brain hurts now.

I can't stand the fact that it took generations to basicaly say "eveloution, something we already belived in happened here to".
-
Perhaps chickens used to give birth like other species? and then one day a genetically mutated chicken made a rudimentary shell around the developing chick. Then bred with other chickens etc.... But i doubt chickens were the first species to make a shell!! I imagine the first egg-layer looked nothing like any creatures we have today. There is a fundamental reason why chickens lay eggs instead of letting the chick develop within the womb....perhaps they scientists should have explored that in more detail
it only takes one mutation to be passed on through generations.

@Oli
I never released you would've been so passionate about eggs?
Next thing scientists will say Santa isn't real

sorry to disappoint you, but it's been me breaking into your house!

It doesn't always take one mutation for a new breed to spark. Such as people that have both anatomy systems. The last I heard, not one of those people have had a child of that situation. It just counts on their parents and grandparents genes.

what exactly do you mean?
evolution is based on mutation is it not
all it takes is one dominant mutated gene and the"flaw" will be passed on. Even if its recessive it will be passed on but may not have an effect.
-
People that have both male and female parts. Yes, eveloution is based on mutation.. But in my theroy as well as many other's: If treated in "normal" or usual conditions of a species, than one organism's flaw will grow faint and unique. If grown under the normal population and mated with a normal populater, the unique trait will become recesive and later forgoten as only reccesive traits can last two generations.
-
Yes I am not disputing what you've said..... hermaphrodite isn't a direct mutation is it.
@unknownuser said:

What I am saying is....if the conditions are right and the mutation is beneficial to survival then the mutated species would thrive while non-mutants would die. Such as a species of birds who have mutated beaks.....on one island they have long sharp beaks (lots of insects/grubs etc) while on another island the same type of bird has a short, wide beak for crabs etc. This suggests that the two islands have split from one single island where all the birds were the same....so if the conditions are right then the mutation will thrive. This is evidenced all over the world on islands that have splintered from a larger one. Same species, different traits.
The "chicken" must have had reason to cocoon its young in a shell. environmental conditions or otherwise. I imagine conditions in the past were not "normal" and relatively consistent like they are today.
-
I would assume that it is direct mutation. Many who suffer from this, their parents were exposed to some sort of poisons or hazeredous materiels in their life.
-
oh right lol well scrub that! but the rest still stands!
but if hermaphroditism (is that a word?) was beneficial in a given circumstance....it would thrive! this is my point, but yes amongst general population it will fade away.
so how do you go from egg to hermaphrodite? SCF that's how.

I've created a monster
-
If you raise a religon, a new society and, a completly new system of ethics of hermaphadites that mate with themselves, then and only then can you have a species that can over power normal man kind.
And welcome to my world. If you like the avid forums on SCF, try Facebook

lol i've just got the weirdest image in my head.
hahaOK chicken came first let's leave it at that!!
-
Hmmm... It seems like a rather inviting image to me. But anyway. Chicken = Egg
-
Hi folks.
It is quite simple.
The dinosaurs where laying eggs.
The birds evolved from dinosaurs.
The chickens are birds.
Then, the chickens lay eggs.
But ... wait a moment ... what came first ... the dinosaur or the egg ?
Back to square one.
Just ideas.
