Schimpanser och tidiga homonider har en kort tillväxtfas, men tidiga Homo Sapiens (160 000 år sedan) hade lång:

The researchers used synchrotron light at the ESRF and combined a new application of a technique called phase imaging with developmental analysis. “It is the first non-destructive approach to characterize dental development with a high degree of precision, as synchrotron images reveal microscopic internal growth lines without damage to the sample”, explains Paul Tafforeau, one of the authors and developer of the virtual dental paleohistology using synchrotron light. Information on tooth growth in the Moroccan child was compared to other fossil and living human populations to determine if the modern condition of prolonged dental development was present.
