Millions of years ago, there were 2 types of giraffes. Short neck and Long neck.
As the environment changes the only leaves available were high up in the trees.
I'm so lonely, I have no one to mate with! :(
As the leaves were up so high only the long neck giraffes could reach them, not the short neck giraffes.
Short neck giraffes were not receiving enough food and started to die out, due to natural selection.
As the short neck giraffes died out, their were less and less available for reproduction.
Long neck giraffes successfully attracted more females are were able to reproduce
