The mouse - the 'dear' companion of humans

Through the haploid genome analysis of many hamster models in the world, it is possible to find signs of these four rodent growth periods respectively according to the major changes in the calendar. human history.

Rattus Rattus is the scientific name of the famous hamster through the allegorical poems of Jean de la Fontaine. Not so cute as one might think, it is the rat that has " embarked on" some of the tragedies in human history such as plague, lice fever, angiopathic disease . Moreover, this hateful rodent has disturbed our species for a long time since ancient times. Through the mitochondrial test of DNA from 170 mouse models in 32 countries, geneticists have identified six modern Rattus mouse lines derived from an ancient mouse species.

n in 20,000 years ago in India and quickly developed into the Middle East and then to Europe.

This first invasion corresponded to the prosperity of ancient civilizations, followed by the Bronze Age, according to historians, it was the beginning of the ' commercial ' exchanges. Later the mouse also 'annexed' the rest of Africa, America and Australia, respectively, according to the discoveries of new human lands. Another influx of mice in East Asia has also migrated from Taiwan to Japan, from the Philippines to the region of Micronesia 3500 years ago, which corresponds to the period of human settlements in Asia.

Other mouse lines, preferring to " settle down ", stayed in their "homeland " (Himalayan, Thailand, Mekong Delta and Indonesia). This genetic decoding explains why mouse-borne infections may be more common in some areas than the rest of the world. From this we conclude that each rat species may possess a part of their own parasites and microbes. The hypothesis also needs to wait for further studies to conclude, but if it is accurate it can serve to predict and control many future diseases.
