There wouldn't even be apes if it wasn't for dinosaurs going extinct due to an asteroid. Mammals could only be small creatures as long as dinosaurs were in control, but I wouldn't say dinosaurs are superior, for they were sinful killing machines influenced altered by Satan, fallen angels and demons. Hence, day 2 in Gen. 1.9 unlike the other days of restoration was not called a 'good day,' because when the firmament was split unfortunately up came some of those demonic spirits from the deep (or abyss) to negatively impact the creatures on earth in earth's earliest ages before Adam was born in the Garden of Eden 4004 BC. This would explain how the serpent could enter the Garden to entice man to rebel against God which in God's great awareness gave man a fully developed free-will to have the free-choice.
