The existence of a real Adam and a real Eve is regarded as a necessary logical inference from the doctrine from Tradition of Original Sin. Catholics are also required to believe in "Creation from nothing." Other than that, the Catholic Church doesn't hold as doctrine any scientific position regarding human origins. Science and Faith/Morals are separate categories.
When was the last time you attended Catholic school? They ALL teach evolution which deals directly with human origins. As I have cleary demonstrated, you can't separate the bible and evolution without falling into hopeless contradiction - as catholic schools have done. They are fast leaving their first love.
