In a new study on Maya civilization in Central America, researchers have found unexpected changes through ancient Mayan fertilizer samples of 9: 00/2: 24nam southern researchers Dinh and distribute 4 miles of time based on the change of population density and the marked transformation of the climate at that time: 1350-950 BC, 400-210 BC, 90-280 later BC and 730-900 AD. Through specimens, in particular the feces of the ancient people have found the scale of the Change of the Mayan community through climate change. These specimens are found in the ancient Itzan city ( In the Republic of Guatemala today). This shows that people who have lived here are about 650 years earlier than previously given archaeological evidence. Although it is just a small city, itzan is extremely valid by archaeologists by the ruins of the past
. McGill University's Benjamin Keenan University, Canada shared: "These new studies Will give us some information about ancient Mayan people that we cannot find them at any an archaeological tracing. Because the Mayan people often live in low-lying areas in tropical forests, which are not suitable for conservation of important architectural works and materials. "Ancient architecture of Maya civilization
Save the use of stanol separation methods - organic molecules in people and animals. This stanol is often found in sediments in the lake river, dating back to thousands of years. So far, stanol has been shown to be an important indicator to determine the number of people who live in a certain location. In addition, the research team also contrasts the recently obtained data and data about Climate in the past, namely: humidity, rainfall, pollen density (plant coatings) in the geological record of this land. Data on stanol extracted in sediment layer in a lake close to the ancient Itzan city showed that the population movement of the ancient people is closely related to past changes in the past. Of the Stanol separation method showed that the population rise was unexpectedly around 1697 when the Spaniards attacked the last Maya success in the neighborhood of ancient Itzan city. This may be an attack, the refugee battle that historians have not recorded. However, there are several locations that have found stanol index too high, not suitable for the volume of stanol in Stool is recovered. Researchers believe that the ancient Mayan has known to use people and animals to make fertilizer for plants. Stanols in ancient people play an important role in specifying the changes of Mayan populations
At the same time also provide important data on the ancient people who use and renovate land. Tuantheo Science Alert . Dịch vụ:
