Scientists have studied the living conditions of the children of Neanderthals

Anthropologists have studied the composition of the two Neanderthal teeth kids and found out many important details of their hard lives, including the confrontation between harsh winters and lead poisoning.

The fossilized teeth belonging to the two Neanderthal children were recovered Payre, a site in the Rhone Valley, southeast France.

An global team of anthropologists conducted an analysis of teeth belonging to the children of Neanderthals, who lived in France about 250 thousand years ago.

Results of the study will be published online in Science Advances, a journal published by the American Association for the Advancement of Science, at 2PM EST on October 31st.

The worldwide research team of biological anthropologists, archaeologists, earth scientists, and environmental exposure experts measured barium, lead and oxygen in the teeth for evidence of nursing, weaning, chemical exposure, and climate variations across the growth rings in the teeth. During childhood, new layers of teeth are formed each day, causing chemical signatures that scientists can track. Tanya Smith, a biological anthropologist at Griffith University in Australia, along with colleagues performed a CT scan of the remains and then cut each tooth into thin slices. Because teeth have these tiny timelines, we can relate the chemistry to the growth to calculate ancient climate records. "That's possible because when you're growing, your teeth you actually lock in a record of the chemistry of the water and the food that you're eating and drinking". "Winter" enamel they are very weak, and scientists believe that during these periods the children of Neanderthals was sick and starved very often, losing weight and much fainting. The trouble with them in the Neanderthal mothers were nothing less than modern - modern children. The children were forced to endure the heat of summer and dry cold in the winter.

Could The Bear Market Last Two Years?
Hayes believes that the current bear trend on the crypto market could last for an 18 month period until the middle of 2020. Do you think Arthur Hayes is right about his 18-months of additional bearish markets prediction?

It is believed that, in contrast to our direct ancestors, the Neanderthals were "indigenous Europeans" and well adapted to life in the harsh conditions that existed on the continent thousands of years ago during the ice.

"This study reports a major breakthrough in the reconstruction of ancient climates, a significant factor in human evolution, as temperature and precipitation cycles influenced the landscapes and food resources our ancestors relied on", Smith said in a statement.

"We were able to identify milk intake through breastfeeding in one individual based on a trace element called barium", Smith told CNN. For comparison, Australian scientists took the teeth of Neanderthal children, who lived in modern French territory, as well as kids person. A one-of-a-kind new study is filling in the blanks, providing unprecedented insight into the lives of Neanderthal children.

"Dietary patterns in our early life have far reaching consequences for our health, and by understanding how breastfeeding evolved we can help guide the current population on what is good breastfeeding practice", said Manish Arora, Professor and Vice Chairman Department of Environmental Medicine and Public Health at the Icahn School of Medicine. The ages of the children were not included in the study.
