Craig Packer

Early years

Packer was born in Fort Worth, Texas in 1950. He attended his local Eastern Hills High School in 1964 and graduated in 1968. Growing up, Packer was originally interested in being a doctor or an engineer, and originally sought medical school after graduating from high school. However, these fields did not support his desire to work out in the field and to travel to exotic places. Furthermore, Packer was fascinated by evolution and animal ethology. He ultimately abandoned his place in Stanford University’s School of Medicine to work as a field assistant for Jane Goodall in Gombe National Park, Tanzania to study olive baboons. He eventually graduated Stanford in 1972 with a bachelor’s degree in Human Biology. He later attended the University of Sussex to complete his doctoral research on baboons, graduating with a Ph.D. in Behavioral Ecology in 1977. After a subsequent study on Japanese macaques in Hakusan National Park, Packer returned to Tanzania in 1978 as the head of the Serengeti lion project. His interest in lions derives from their unique behavior as social carnivorans, and it is a passion he continues to exercise as director of the Lion Research Center.

Baboons

While studying at Stanford, Packer was sent to Tanzania to study baboons at the Gombe Stream Research Center with Jane Goodall. During this study, Packer was one of the first ecologists to study complex hypotheses about the adaptive significance of behavior in his studies of coalition formation in baboons and the reasons why male baboons dispersed from their troop of birth to new troops. Packer attended the University of Sussex to complete his baboon research.

Serengeti Lion Project

In 1978 Packer began the Serengeti Lion Project to study various historical questions about lions. One of his biggest contributions to the Serengeti Lion Project was the discovery that successive outbreaks of canine distemper virus had different impacts depending on the rainfall patterns from the previous year. Packer studied how severe droughts led to co-infections of canine distemper virus by a tick-borne parasite, babesia. The co-infection mixed with high levels of babesia showed to be far more fatal than the distemper virus itself.

Packer also studied the effects of a full moon and its correlation to the number of lion attacks. Along with his colleagues, they discovered that the risks of man-eating attacks are highest during the first week after the full moon, which may help explain why there are so many myths about the full moon. They also discovered that people in southern Tanzania are most at risk from man-eating lions in areas where they have to sleep in their fields to protect their crops from nocturnal crop-pests such as bush pigs. The lions stumble upon a novel prey species when they follow the pigs into people's fields.

Family

Packer has two children Jonathan (1987) and Catherine (1984) and is married to Susan James.
