ANSWER 1
You actually can not 'summon' a homunculus. But you 'create' it. In Fullmetal Alchemist, a homunculus is created by human transmutation. Since human transmutation is impossible, the result of the attempt to do human transmutation is a 'failed human' or known as homunculi.
At first, the homunculus would look unhuman, like when the Elric brothers tried to revive their mother, it was shown that a monster was created (it's ribs were not covered by skin and the heart could actually be seen, the facial features were unlike their mother, Trisha Elric). But after the homunculus consumes philosopher stones, they regain a physical posture like the human they were supposed to be, but with extraordinary regenaration powers.
In real life though, the existence of homunculi is debated (see the related link below for more information). No record of a living homunculi is ever reported.

The Tattoo of Oriboris indicated that the bearer of the tattoo was not human, but a homunculus.

I think they're mostly just design features, but they could have something to do with the fact that they're made with philosopher's stones as hearts

Your question contains a double negative. I am sure you meant that the Homunculus theory, couldn't explain stages of development. In Psych 101, late 70s, we ridiculed the Homunculus theory for not taking into account stages of development. Like Piaget or Erikson. I think it is sad that now if a 3 year old doesn't have an adult attention span, we put him on Ritalin. Guess the Homunculus theory has returned.
