Theory : Titans are the dead people that have been regurgitated after being eaten. I think this is why they keep "eating" humans even if they don't need them. Kind of like how Vampirism and Zombie viruses spread. Their goal is to infect humans to become like them. This is how their numbers kept increasing even though they have no genitalia.

The whole titan situation looks like an experiment gone wrong, but you can see the postive effects of it with Eren, where he has better regeneration than ordinary humans and the ability to summon a giant body to protect himself.

In episode one of the anime when the scouting legion attacks the lone titan, if you look closely enough, there appears to be a human shape in the nape area. I'm guessing that the transformation overwhelms the human consciousness but because of the Serum given to Eren, he was able to retain his consciousness and take control of the transformed body.
