Discussion
- Males are assumes to differ from females by {p_Am} only
- Male {p_Am} jumps upward at puberty, as discussed in Kooy2014 under type A accelerationThe male growth curve could fit better if puberty was dealed with as a period, rather than an event
- In view of low somatic maintenance, k has been targeted to 0.1 and pseudodata for k_J removed
Facts
- largest sex difference among mammals; can dive till 2.133 km (Ref: Wiki)
- gestation time of 11.5 month include 3-4 month delayed implantation (Ref: AnAge)
