Why do you think your paper is highly
It is based on long-term and careful monitoring of wild chimpanzees in the
Mahale Mountains National Park, Tanzania, Africa.
Does it describe a new discovery, methodology, or
synthesis of knowledge?
Demography provides critical data to increase our understanding of the
evolution, ecology, and conservation of primate populations. It's a new
discovery which includes the lack of menopause among wild female
chimpanzees and it also documents many of the demographic parameters of
Would you summarize the significance of your paper
in layman's terms?
This paper reports on the number of infants female chimps have in their
lifetime, the causes of death, long-term population dynamics, the extent of
female transfer, which is influenced by the size and composition of the
unit group and size of the overall local community, the lack of menopause
(namely, human menopause is unique), and many other demographic
characteristics of wild chimpanzees.
