Scientists have responded, more than human ancestors ate

Scientists constantly study our ancestors to answer many questions about their lives. One of the tools that helps in this case, is the isotope analysis of the bones: so, thanks to him, we found out what usually ate Neanderthals. The study is published in the journal Proceedings of the National Academy of Sciences.

Scientists have responded, more than human ancestors ate

According to experts, the main diet of Neanderthals consisted of meat of grazing animals - deer and horses. To do this, anthropologists studied the remains of Neanderthal man with the help of the newest method CSIA: he gave information about the origin of certain chemicals. Exploring the isotopic composition of nitrogen, the researchers concluded that the carnivorous share of the heavy isotope of nitrogen is higher than that of herbivores. Measurement of the indicator Neanderthals (of teeth) showed that they were fed meat animals.

This is indicated by the high proportion of nitrogen-15 in the tissues of the Neanderthal, which suggests that it was a carnivore. What exactly he was eating? Scientists agreed that mostly for breakfast, lunch and dinner, he had the reindeer and horses. This contradicts earlier studies that Neanderthals ate rotten meat to increase the nitrogen-15 content. Also, scientists do not rule out that the food is pre-treated. The question of when man began to use fire for cooking is still the subject of heated debate. Some scientists believe that there is still 1, 8 million years ago. Traces the use of meat or fish predators at the same time were found. Earlier analysis of plaque on the tooth ancient Neanderthals showed that they can adapt to different types of food, and also revealed the presence of deposits of inedible vegetable origin, the remains of the wings of butterflies and other parts of the limbs of the ancient species of insects. Therefore, clearly define the diet "ancient people" is still difficult.
