I noticed something, in the flashback Berthold has during training where he opens a window and sees a titan (http://www.mangareader.net/shingeki-no-kyojin/13/16),the titan he is seeing is a monkey.

it's hard to see because the page is so dark, but if you look closely you can see that the titan has hair covering his cheeks like the monkey we see later.
