Tecoyah,
Q1) I watched documentaries many years ago. As far as I remember, the giraffes' necks all have the same number of bones but natural selection chose the taller bones.
This is very important because that means that evolution was a result of natural selection. The giraffes' with longer neck bones managed to reproduce and gave birth to giraffes' with longer neck bones. This is normal reproduction > evolution > adaptation.
Now if and only if the tallness of the giraffe came because the number of neck bones increased, then it would be a totally different story! This means that a new bone object was written in the DNA and fitted in the write manner to be in the neck. This would have meant that evolution was able to create. But its scientifically impossible for new information to be created on its own (in the DNA).
Q2) new info, sounds interesting. But gotta go sleep, I'll check it tomorrow.
good night
