which one came first?

[opuntia]

egg or bird?

[b_d_41501]

The Bird, or there would be no egg. But others will say the egg, or there would be no bird.

[comedian]

Wouldn't it be the egg, because chickens are descendants of reptiles?

[James]

Well, yes kind of

[Dr.Stein]

Egg.
According to Developmental Biology: Simple thing can differentiate into complex thing, whereas complex thing never turns back into simple thing

[MrMistery]

Of courser the egg came first. Insects lay eggs, fish do, amphibians etc...
If you mean which came first: a bird or that particular bird's egg? Than the answer is the bird
The bird, the first of the particular species, appeared via mutation, then it started laying eggs

Omne ovum ex ovo??

[MrMistery]

Excuse me?

[Dr.Stein]

Omne ovum ex ovo??

Omne vivum ex ovo
Omne ovum ex vivo
thus,
Omne vivum ex vivo (biogenesis)

But nothing about omne ovum ex ovo

[Poison]

Excuse me but just out of curiosity, what is that?

[Zachthemac]

It's Latin.
Omne vivum ex ovo = All life is from an egg

[Poison]

Thank you...
