According to an analysis by the National Science Foundation, 41 percent of the people who received their biology Ph.D.s in a recent five-year period earned their bachelor's degrees from 70 leading research-intensive colleges. Next on the list were other doctorate-granting institutions, comprehensive institutions, liberal arts colleges, and specialized institutions (such as engineering schools and military academies). Liberal arts colleges accounted for only 8 percent of the undergraduates in four-year colleges and universities but for nearly twice as many of the eventual Ph.D.s. The same study revealed the special importance of several types of institutions. Among African Americans who earned Ph.D.s in the biological sciences, for instance, 42 percent attended historically black colleges and universities as undergraduates. Also, of the 12,334 people who received biology doctorates between 1987 and 1990, 1,073, or 9 percent, began their undergraduate education at two-year colleges.
