Young hominin from #Dmanisi 1.77 mya shows a slow pattern of molar development in the first 5 years.
'the researchers compared the Dmanisi teeth growth trajectories with those of humans, chimps, and other apes. For the first 5 years of the Dmanisi youngster’s life, its molars developed slowly, so that it kept its baby teeth longer and developed more like a modern human than a chimp. Then from ages 6 to 11, its teeth developed and erupted more quickly, like a chimpanzee’s. Overall, the youth matured faster than a modern human, but the early slowdown in growth is the oldest known example of such a pattern and may be the first step toward our own delayed development'
