Research evolved through teeth 30,000 years ago

Children's teeth that once lived 30,000 years ago were a very important part that scientists collected during a survey in the Abrigo region by Lagar Velho, Portugal in 1998-1999.

The survey was carried out by Professor João Zilhão of the University of Bristol and colleagues. With today's scientific advances, the analysis of those teeth gradually reveals the mystery of human evolution, including the Neanderthal movement from Africa to Europe.

Modern people in the early stages of development were about 50,000 years ago, basically the body structure is not much different from the present man, the biological change is also negligible.

The international team of scientists analyzed the teeth collected at Abrigo by Lagar Velho, compared with Neanderthal teeth that lived 12,000 years ago and humans today to find differences between periods. Using micro-cutting techniques combining X-rays to create 3D images (photos), from which scientists study the ratio of tooth components such as enamel coating, dentin and pulp. .

Information shows the development of forbidden teeth and the incisors of the ancients are slower than today. Besides, for incisors, dentin, pulp is quite high but less yeast compared to people today.

The collected teeth at Larga Velho show that humans have continually evolved to develop from 40,000 years ago, the word 'not fully modern' until 'modern money' and then modern.
