I suggest the explanation of this is "intraneural" competition. The
human brain, being larger, requires more of the mechanism/s for growth
and development so it competes better than the spinal nerves for
myelinization. Therefore, myelinization of the spinal nerves,
necessary for walking, is defered in humans.
