1 Chimpanzees have a long mother-infant dependency period. 2  Infants will nurse on their mothers for five years and stay with their mothers several more years learning to care for younger siblings. 3  The life span for chimpanzees is 40 to 50 years in the wild and over 50 to 60 years in captivity.
The average mutation rate was calculated from the average autosomal rate of evolution assuming a generation time of 20 years (Table 3). Recent estimates of the time since humans and chimpanzees diverged (T) include 4.5 mya (TAKAHATA and SATTA 1997), 5.5 mya (KUMAR and HEDGES 1998), and 6.0 mya (GOODMAN et al.
