One Giant Leap for Monkeykind

Spanish Parliment to extend rights to Apes. It's all too silly to even talk about, but apparently we are closer to granting apes the unalienable right to life:

Philosophers Peter Singer and Paola Cavalieri founded the Great Ape Project in 1993, arguing that "non-human hominids" like chimpanzees, gorillas, orang-utans and bonobos should enjoy the right to life, freedom and not to be tortured.

My questions for Peter Singer: if you kill an ape baby in utero, is it murder? What if an ape chooses to kill its baby in utero? What if the monkeybaby is mentally challenged?
