- 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).
- Embryo 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.
