A Short History about Rats

Rats have an interesting history with humans, some good and some not so good.

Short rat HistoryRats have a very long history. It is believed that first group of rats, the Norvegicus Rats (Known as the brown Rats) origins go back to China and Mongolia, original call the Asia plains, where their ancestors used to live in burrows over 160 hundred thousand years ago. This group of rats revolved from the Anagalids. Some wild rats still live there today.

The rats that we are most formally with are called Rattus, they evolved around 4.5 million years ago in the Mediterranean countries.  They split into two different groups around 2.5 million years ago.  From there they have into over 51 different species groups

They connected with humans as our race was developing, over several thousand years ago. From this and with properly some unknown help from humans they work their way around the globe.  Rats were possibly used as a source of food at that time too. I know some countries today still have rats on the menu.  These are normality undeveloped countries where rats are a free source of food.

Rats got a bad reputation for being thought responsible for the Black Death plague through the middle ages killing millions of people, however, they may not off been responsible. See articles in national geographic – https://news.nationalgeographic.com/2018/01/rats-plague-black-death-humans-lice-health-science/.  This is properly why humans do not like rats too much, and it properly not even their fault.

Using Rats to torture people in the seventeenth century would not of help their reputation either. This is where a person place on a bench then tie to it.  Then a cage of Rats is put on their stomachs and then the rats would eat the person. Not a good way to die.

Rats started to become more popular as pets around the start of the nineteenth century.

But the truth is us humans should be grateful to our Rats friends as they have helped us in a lot of different areas in research, especially in the medical research area which is still happening today.  Today any rat keep for research purposes is a lot better look after then it was in years gone by. They are properly even having a better life than most rats on the street.  However, this research has also been a help to the rats too. It has helped work out what is a good rat diet for them, what rat cages are best for them.  A good example of this is in the book, The China Study by T. Colin and Thomas Campbell, which refer to research done in regard to Rat’s diet. It brings up the research where rat fed on a high protein diet versus rats fed on a low protein diet.  The rats feed on the high protein diets did not survive as well as the one on the low protein diet. This was a big test study in relation to tumors and cancer research. With the results from the study, being helpful to both the human race and pet rats.
