In skeletal muscle cells, 

a low cytosolic Ca+2 level is maintained by a unique Ca+2 ATPase that continually pumps Ca+2 ions from

the cytosol containing the myofibrils into the SR, establishes a reservoir of Ca+2 in the SR.

Rate of evolution = Number of amino acid different / Total time

Hint:  Total time = 2xT

Rate of Change per amino acid per year = rate of evolution / total amino acid
