The maturing of the corpus callosum by middle childhood is especially important for motor coordination.

Explanation:

The corpus callosum is the part of the brain which is effectively involved in signal transmission. The signal transmission across the right as well the left hemisphere is the main function of the corpus callosum. The transmission of effective and correct signals comes under the control of motor coordination. Hence, the maturing of the corpus callosum is especially important so that effective transmission of signals through motor coordination can happen.

not sure if this is what you'r looking for eubacteria and archaebacteria
