Taung Child is believed to have been about three years old at the time of its death. It was a creature standing 3' 6" (105 cm) at approximately 20-24 pounds. Taung Child had a cranial capacity of 340 cc, living mainly in a savanna habitat. Examinations of Taung Child compared to that of an equivalent 9-year-old child suggest that "A. africanus" had a growth rate to adolescence which is about the same as that found in modern apes like chimpanzees rather than that of modern "Homo sapiens". However, later species such as "Homo ergaster"/"Homo erectus" went through growth at rates between modern humans and apes. The evidence has mostly been based on that of Turkana boy discovered in 1984.
