Evolution is a THEORY, not science.
Science develops theories. It appears he is using theory as is commonly used in the public spectrum; as just an idea. Science uses a different definition.
If the animal had a short neck to begin with, then what did it eat for millions of years? Obviously it would have had to eat food from off the ground.
Sure, some of the food that the giraffe had eaten was from off of the ground, but think of the advantages of having a long reach with your neck?
With a long neck the giraffe could reach an abundant source of food cut off from so many other organisms, food high up in the trees, in addition to being able to eat food from "off of the ground".
Gotta run, heading to work.
