Yes, these two arguments do follow the same logical form. Both arguments are just stating a characteristic that is common regarding the two things being compared in the premises. Just because both superheroes and kick-ass are strong, does not mean they are the same because a lion is also strong but would not be considered a superhero. In the same way in argument one does the same thing. In order to prove that microcephalics are human, you need to describe what makes something human.
