Let say 5 million years ago the giraffes ancestor's neck was 2 inches long, then a random mutation occured that made one giraffes ancestor's neck a couple inches longer and then that individual could eat leaves higher in the branches and survive and pass on the genes. Today the giraffes neck is like 60 inches or longer, so does this mean that an additional random mutation needed to occure for each incremental increase in the giraffes neck. For example the neck was 2 inches, then 4, then 6..... and so on, with an individual random mutation responsible for each increase. Or was it just ONE initial random mutation that occured 5 million years ago and the rest of the length increase in the neck occured because of other reasons.
