Mexico -based Memouth DNA has revealed a different lineage

Long before the construction of the Philip Angeles International Airport, northeast of Mexico City, the former was a former lake Zaltokan in the area and contained a rich environmental system of prehistoric animals. After Evans, in 2019, the airport began to have a controversial construction, which did not detect the gossip of many other animals along with at least 110 individual mammoths.

The gynecologist assumed that the memorandum would be genetically the same or that would be similar to the Colombian Memoh (Memotos Columbi). This is the only type of Memon from North and Central America. The second species of Memonship found in North America is the woolen Memon (Memon Premier), which has clearly migrated from the Eurasian continent and is mostly found in Canada and the United States. However, the beginning of Colombia’s mammoth is less clear.

Past research suggests that Colombian Mammothy is born from hybridization between Mammoths and another species of Eurasian, stop Memonth (Memotos Troygwanthi), which was about 800,000-400,000 years ago. It seemed as if these memoxes were similar to those found in Mexico.

However, a new study, which appeared Science The Felip Angeles International Airport paints a different photo by analyzing the mateconadel DNA of the mammoths found during construction, as well as samples from a mammoth excavated between 2016 and 2019 on a site of the nearest Tiltipic.

Often, it is difficult to extract DNA usable for analysis in tropical, as DNA usually does not benefit well in hot climate. On the contrary, many wool and staple Imomothy found in the north are contrary to the DNA sample. Therefore, Colombia’s first Memon’s DNA came from the Jovashim found in more north of North America. The use of a dental dental DNA instead of nuclear DNA was a way around the problem, though only maternity lineage can be studied in a way that cannot reflect nuclear genome diversity.

The study revealed a separate mammoths of Mexico’s mammoths, known as Claid 1G, which is separate from North America’s second mammoth. There were further grouping within Clead 1G. The groups involved in the Mexican group showed a much deeper genetic deviation than expected, the difference between Cleud 1G is equally large as a turning point in North America’s second large -scale tissues.

The authors offer two specifications for these results. “First, the ancestral population of M Premier could have a structure at the mutoconerial surface that gives birth to M -Columbi before the Hybridization event with the Cristica lineage like M. Troghwanti. Secondly, this sample has different times of various Metogenis.

The authors of the study noted that they are inclined towards the first explanation. Researchers also used radio carbon dating to determine the ages of Jovashim, which states that they live between 40,000 and 12,700 years ago during various lineosis.

This study eventually sheds light on the difficulty to analyze species. He says, “This study emphasizes the importance of recovering ancient genomic data from ancient geographical boundaries to fully understand the evolutionary speed of the nasty species, and reflects the recovery of DNA from the latest plystosine patterns from the inflammatory application.”
