Study found that human ancestors often eat fish
Researchers from the Chinese Academy of Sciences and the Max Planck Institute in Germany conducted a stable isotope test on the remains of early modern human remains unearthed from the farmland at the Zhoukoudian site in China, as early as 40,000 years ago, in the human food structure. Fish has a large proportion.
The Max Planck Association issued a press statement on July 7 that whether regular fish can be analyzed through the analysis of bone collagen in bones. In the new study, researchers performed carbon and nitrogen isotope analysis on the remains of pastoral cave people and related animal remains.
The results showed that the content of animal protein in early modern food was high. It can be inferred from the higher nitrogen isotope test values ​​that early modern people often eat freshwater fish.
In order to verify this inference, the researchers conducted a sulfur isotope test on the bones of terrestrial and freshwater animals in the Zhoukoudian area, and compared it with the sulphur isotope values ​​of the pastoral cave people. The results also support the large proportion of freshwater fish in early modern foods. Proportionality.
Michel Richards, a German researcher who participated in the study, said that the latest research shows that early modern people used to eat fish, but there was no archaeological evidence of fishing tools at the time. It may be a lot of work.
The research team published research papers in the new issue of the "Journal of the National Academy of Sciences". They believe that this analysis provides direct evidence for "China's early modern human consumption of aquatic products" and will help to further understand the lifestyle of early modern people.
