Bioflex how do you explain vestigial organs like whales with vestigial legs ...google it. The genes for vestigal organs are still there...like humans in the womb get a complete covering of hair at PRECISELY the same stage as apes do, but because our fur gene is 'switched off',dormant if you like, we loose ours.
Some animals DO MOURNE their dead. Some human animals dont. How many times do you see someone killed on tv, or witness an accident and just continue on with your life...no tears shed. The point being made is that no loving god in the Judeo-Christian sense could have created a world based on predation of other (or in many cases their own) species.
