but where did the proto-chicken come from

[YanxtarVideos]

@2eraz1 The proto-chicken was born from an egg laid by its proto-chicken mother. If you're asking where it came from in evolutionary terms you would have to look at its roots of origin as a specie. Birds are speculated to have evolved from reptilian animals millions of years ago!

but the proto-chicken came first!? thats a chicken, right? :D

[YanxtarVideos]

@xostrikexo In actual fact, it's not! The proto-chicken wasn't very different to today's modern chicken but just enough to (biologically) classify it as a different specie.

Which came first? The proto-chicken or the proto-chicken egg?

[yvranx]

Wow, that is a bad explanation! Mainly because it's wrong.

Species evolve as a whole, so there never was a single chicken or egg that was first, the modern chick phased in over multiple generations.

You are also ignoring the obvious follow-up about the proto-chick and the proto-egg, which evetually has to end somewhere. The reply is that the original question assumes a high degree of identity that is simply not there.

-F- this! LIFE came first! Then it changed and morphed into stuff, giving the proto-chicken which gave the proto-egg, which gave the chicken which gave the egg. It's a simple nonsensical answer, but the best ones usually are. :P

[Petrico94]

The egg came first but the chicken egg came later.

also, the proto chicken laid the egg but a chicken came out so the real question is who's egg is it, the almost chicken, or the chicken inside

YAY I WAS RIGHT :D

[satanisthetruegod666]

@stevjen1 born in a membrane sac... what? that makes no sense, the ancestors of birds have been laying hard shelled eggs since the Ordovician if memory serves. And if it's found in 'bird ovaries' it's likely that their ancestors had the same genes to produce OC-17 and thus the egg came first. In fact counting soft eggs they almost go back to the beginning of multicellular life!

and i'm well aware that chickens didn't occur because of single mutation, no species does.

[stevjen1]

@satanisthetruegod666 OC-17 is found in bird ovaries. Chickens are from proto chickens or birds, but not over a single mutation. it most likely took thousands if not millions of years. Thats how evolution works. Very gradual. The birds have been traced to the red jungle fowl through DNA sequencing and comparing the numbers. Chickens as we know them now are about 7,000 years old. First chickens most likely born in maybe a membrane sac where many chickens died!

[satanisthetruegod666]

@stevjen1 and it's absolutely impossible that a proto-chicken would have OC-17? or that even reptiles would have it? or at least one like it that would allow them to produce eggs with shells?

[stevjen1]

WRONG. the chicken came first. a protein called OC-17 ovocledidin converts calcium carbonate. OC-17 clamps its molecular fingers onto a microscopic particle of calcium carbonate That creates a nucleus, from which the calcium carbonate can crystallize. When the particle nucleus gets big enough, OC-17 can no longer hold onto it. The molecule's fingers detach, leaving it free to grab onto another nucleus and repeat the process. The chain reaction continues until the eggshell has formed.

@janjan517 Then, who made "god"?
