Hi Andya and quetzal, thanks for responding so quickly
You are both using the term vestigial organs very frequently and Andya even mentions the yoc sac in the mammalian embryo to be an ancient leftover.
I have have to mention that sciencist document that they have been witnessing a constant reduction in what was previously called vestigial organs.
The yolk sac is one of the protective membranes surrounding the embryos of birds reptiles AND mammals. The embryo derives nourishment from the yolk sac via a system of blood vessels. In birds and reptiles the yolk sac encloses the yolk but in most mammals a fluid replaces the yolk.
So it isnt a vestigial organ.
And this isnt the only mistake that has been made. The constant reduction of vestigial organs since the latest fifty years have only one answer, knowledge replacing ignorance.
According to the theory of common ancestry between reptils and mammals, answer this question please: The differences between those two groups isnt only that one lies an egg and the other gives birth to living creatures although none of you succeded in answering that previously (without stating that species such as the therian reptiles where transitional forms, they had only ONE way of giving birth and no sign of an alternative way on its making).
There are also more differences: reptiles are cold blooded and mammals are warm blooded, reptiles have scales and mammals have hair(the previous example of the hair of the human eyebrow existing only through mutation is appliable here).
More examples is the jaw and the ear, all the mammallian ears consists of three bones and the reptilian of one, the jaw structure is also very different where on mammals all the teeths are located on a single mandibular bone but on reptiles there are three bones in each mandibular side.
Evolutionists claim however that the single reptilian earbone evolved into three, this theory has been disproved because no such fossils have been found(not even one that implies that that transitional bones are on theyre making), and the question of how the species would be able to hear or eat or (give birth mean while) is unanswered by evolutionists.
So if evolutionists claim some theories, why dont they back it up with proofs instead of speculations.
This is why the famous evolutionist paleontologist Roger Lewinis forced to state in an interview: "The transition to the first mammal wich happened in just one ore mostly to lineages, is still an enigma"
