Neanderthals Grow Teeth Faster Than Modern Humans – All Pages

National History Museum

Neanderthal teeth appeared four months earlier than modern humans

Nationalgeographic.co.id—Neanderthal is an ancient human who lived at least 200,000 years ago during the Pleistocene Age. Turns out baby Neanderthal grow faster than other human counterparts. Researchers investigated fossils found in Croatia and found that tooth Neanderthal grew four months earlier than modern man.

Reported from National History Museum, the researchers suspect this may allow them to start eating more food and give them the energy to support their early growth spurt. One of the experts involved in this study, Professor Helen Liversidge who researched Anthropology Tooth at Queen Mary University said that the speed of growth tooth human and Neanderthal is a hot topic of discussion.

“Some say that the latter grow faster, but others argue that they fall within the range of human variation,” Professor Helen Liversidge told National History Museum.

“This is the first time we have tooth baby Neanderthal what we can conclude from the growth of the roots, is tooth it erupted early or not. We found that it seems tooth grow faster and tooth their milk grew earlier than today’s humans,” he continued.

The findings of these experts have been published on the Proceedings of The Royal Society B page under the title Growth of Neanderthal infants from Krapina (120-130 ka), Croatia on November 24, 2021. In this study, the experts used dental findings from the Krapina region, Croatia. There have been found the bones of up to 80 Neanderthals.

The research team used primary teeth recovered from excavations at the site to investigate how Neanderthals grew during the earliest part of their growth. Through the teeth there are many things that can be known from a person.

Teeth have a high mineral content, making them good candidates for fossilization. This allows scientists to find clues about the past. Comparing ancient teeth with modern examples allows scientists to infer how development may have changed.

“The teeth have a history of our development in them. Even our adult teeth, which grow from birth to around the age of 20, tell us a lot during the growth process. But baby teeth start to grow from before birth and during the first three years of life, so we can know more about that,” said Helen Liversidge.

Previous research has linked teething to brain development in modern humans, other hominids and non-human primates such as chimpanzees. Scanning the inside of teeth allows scientists to estimate how quickly they grow and emerge, but this process remains difficult to decipher.

“Eruption and tooth growth are two separate processes but occur at the same time. It’s quite complicated and we still don’t really understand the theory even though every child in the world has experienced it,” said Helen.

Neanderthal human reconstruction. Neanderthals are an extinct species or subspecies of ancient humans that lived in Eurasia until about 40,000 years ago.

Based on the scans it was found that certain teeth such as incisors in Neanderthals grew faster. Molars, on the other hand, grow at the same rate but form enamel more quickly. Overall, these ancient human teeth emerged from the jaw about three months earlier than humans in Europe today.

This appearance suggests that Neanderthals also weaned faster from breast milk and ate a variety of solid foods. Neanderthals themselves are known to eat a variety of solid foods, including red meat and others. This is consistent with previous research, regarding young Neanderthals weaned at about four months of age.

The extra energy that will be given allows the energy needs of the developing brain to be met. Neanderthals themselves are known to have larger skulls than Homo sapiens.

Still associated with early growth may also be necessary because of the early death of these early humans. As many as 85 percent of Neanderthals are estimated to have died at the age of 40. Although the reasons are unclear, it is suspected that their population is facing severe environmental stress.

The debate over the level of development of the species itself is impossible to resolve. Helen said it was very difficult to say whether this Krapina sample was representative because there were only a few teeth.

“Historical samples give us very little information about how to interpret these fossil teeth, but we will need more samples to produce a clearer picture.”
