To understand the evolution of the human form, information about both soft and hard tissues of our ancestors is needed. If chimps are somewhat uncooperative, it can be safely said that hominid fossils are unforgivably reticent about the age at which their teeth erupt, as fossils can’t be observed teething in real time and don’t have gums.
