The giraffe's heart is one of the most powerful among animals today. It needs to produce enormous pressure to get blood all the way up its long neck to its brain.
This is powerful evidence for a Creator because with such high blood pressure, only special design features around its brain prevents it from 'blowing its mind' when it bends down to take a drink!
This is a problem for evolutionists to explain because without these special features a giraffe bending over the first time to take a drink would die, but if the neck was shorter in the past, then it wouldn't need the special features.
This means that the Giraffe must have been designed with all of its features at once, just like the Bible says!
