And why do many reptiles perform LIVE births? Yet ALL birds lay eggs? Did the reptiles evolve to live birthing? Then why didn't the birds? Or the other reptiles? I dunno and maybe noone knows for sure..that's why there are such varied answers.

The question boils down to opinion.
Is an egg laid by an evolutionary ancestor of a chicken a chicken egg just because it hatches into a chicken, even though it was laid by a proto-chicken? Or is it only a chicken egg if it was laid by a chicken? Essentially we know that eggs preceded chickens but it is a matter of interpretation as to whether chicken eggs preceded chickens. |
