Quote from ZZZzzzzzzz:
We agree that the laying of eggs produces eggs, that produce offspring.
So, a chicken comes from what?
A laid chick egg....
Where did the chicken come from?
A non chicken egg?
Nope...not unless you believe in magic.
Quote from Sam123:
âPut simply, the reason is down to the fact that genetic material does not change during an animal's life.â
That statement is preposterous. Genetic material does in fact change during an animalâs life. DNA mutations effecting sperm and egg cells do happen and can be passed down to offspring and some of these mutations increase the fitness of an animal. Chickens evolved from a long line of non-chicken egg-laying creatures, including the dinosaurs. So the first chicken embryo growing inside the first chicken egg came from a pre-chickenoid ancestor.
Quote from Bitstream:
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.
Quote from Ricter:
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.
