Rebecca Cann was born in 1951 and spent her childhood at Des Moines, Iowa, where she completed her elementary schooling. In a summer, just before she started high school, her family moved to San Francisco, California. In 1967 she entered an all-girl Catholic High School in California.^[2] She earned a Bachelor of Science (BS) degree with a major in genetics at University of California, Berkeley in 1972. She then worked at Cutter Laboratories at Berkeley for five years (1972-1977) after finishing college, where she worked on macaque serum proteins and learned the techniques for constructing phylogenetic tree, which would be pivotal for her later achievements.^[2] She continued at University of California, Berkeley for her doctorate in genetics under the supervision of Allan Wilson of the Department of Biochemistry, and graduated in 1982.^[1] She got a Postdoctoral Fellowship at Howard Hughes Medical Institute (HHMI) of the University of California, San Francisco (UCSF). She joined the faculty of the Department of Genetics, University of Hawaiʻi at Mānoa in 1986.^[3]

Cann laid the experimental groundwork for the concept of Mitochondrial Eve, and the consequent Out of Africa theory. From late 1970s she had collected mtDNA samples from women of different ethnic backgrounds, such as from Asia, South Pacific, Europe and Americans of African descent. The data were used in her PhD thesis in 1982. Following her research, a junior graduate student Mark Stoneking added samples from aboriginal Australians and New Guineans. In 1987, after a year of delay, their collective paper was published in Nature in which their findings indicated that all living humans were descended through a single mother, who lived ~200,000 years ago in Africa.^[4] The theoretical mother of all humans popularly became the Mitochondrial Eve, and the underlying concept directly implies recent African origin of modern humans, hence, the tenet of the so-called Out of Africa theory.^[5][6]

She retains the surname Cann from her former husband whom she married in 1972, right after her graduation from Berkeley. In fact she helped her then husband through his graduate school and only when he finished, she started attending graduate school.^[2]

Cann was featured on MidWeek‘s cover on 19 March 1997 for her Mitochondrial Eve.^[3]
