i think i already explain that to u; chickens or dinos or whatever, they all evolved from different creatures that held offsprings in the womb, then they developed their own mechanisms to lay eggs. that's it.
Yeah, but it's not changing the genotype of the parent. That's the point. Sufficiently mutated egg/sperm cells resulted in a chicken, from a non-chicken bird. Z's use of the word "full-fledged" is an attempt to divert. The difference could well have been tiny. But a line could be drawn somewhere with sufficiently sensitive measurement.
yes, scientists and zizzo got it terriblty wrong and we can publish our findin' in the lancet to prove that.
Why are you laughing? You think the word "chicken" completely encapsulates the reality that it represents?
If it walks like a chicken, clucks like a chicken, is as fearful as a chicken, and lays chicken eggs.....
