Papio anubis, olive baboon

Papio anubis (olive baboon, Kenya babboon, Doguaera babboon) is part of a complex of closely related African baboon species which are among the largest non-hominid members of the primate order.
All baboons have long dog-like muzzles (cynocephalus, "dog-head"), close-set eyes, heavy powerful jaws, thick fur except on their muzzle, a short tail and rough spots on their protruding hindquarters, called ischial callosities.
Baboons are quadrupedal, mainly terrestrial primates, highly adaptable and are able to find nutrition in almost any environment.
Olive baboons are highly social animals, with a complex multi-male, multi-female social structure. Members of a troop travel, forage, and sleep together. An average troop may be comprised of 39 to 97 animals made up of a few male, many females, and their young.
Papio anubis is the most broadly distributed baboon species, ranging through most of central sub-Saharan Africa. Isolated populations occur within the Saharan region. They are found in savannah, grassland steppe, and raTreerest habitats.
Homo and Papio diverged ~25 million years ago, and their genomes are ~6% different (four times more divergent than Homo and Pan).
The olive baboon provides a robust primate model for the study of schistosomiasis, malaria, and other important parasitic infections. Also, the Olive baboon is a popular animal model for reproductive and surgical research.

Average ovarian period length is 33.2 +/- 4.0 days (Hendrickx and Kraemer, 1969).

Interbirth interval is about 2.1 years (Smuts and Nicolson, 1989).

Prenatal
- Embryo MeSH Average gestation period is about 180 days (Herring et al., 1991).
Post natal
- Neonate Neonate weighs approximately 1068g and has a black coat, making it easy to distinguish from older infants.
- infant An infant is completely dependent upon its mother for the first few months, until it begins to eat solid food and is able to walk on its own; weaning typically occurs around 420 days of age.
- Juvenile From 1-1.5 years old until sexual maturity and attainment of adult size. Juvenile mortality (before 2 years of age) was 48.7% as observed for period of 4 years in Kenya (Smuts and Nicolson, 1989).
- Adult Age of attainment of sexual maturity and adult size is greatly dependent on nutrition levels and varies from 7 to 10 years old for males and from 6.5 years to 8 years for females; baboons in captivity have been known to live up to 45 years, in good conditions or in captivity average life expectancy for male is about 25-30 years.
