The role of rats is important in all the progress that science has made. Scientists do an experiment on humans only when it proves to be correct on rats. Especially medical or pharmaceutical related experiments. Now the question arises that when there are millions of creatures on this earth, then why do scientists do experiments only on rats. Let us know the answer to this question in this news today.
Why are experiments done only on rats?
Rats and humans are very different from each other, but there are many similarities in their genome. Both rats and humans are amazing worms, whose dna is similar to a great extent. In simple words, many biological processes and systems in the body of rats and humans are similar. For example, the immune system, brain structure, hormonal system and organ function are similar to a great extent in both rats and humans. This is the reason why experiments are conducted on rats before doing them on humans. This helps in knowing how the results of the experiment will affect the human body.
Rats have a fast effect
Apart from the similarities between rats and humans, there is another reason why scientists use rats in the lab. That is, the effect of any experiment on them is very fast. Because of this, scientists get the opportunity to measure the effect of medicines quickly.
It is easy to keep rats in the lab
Rats are such creatures that can be kept in a controlled environment in the lab. Here all aspects of their diet, lifestyle and behavior can be easily monitored. This helps scientists to understand how diet, weather and even air quality affect the experiment. Apart from this, rats are also used for experiments because their lifespan is short and they breed fast. Apart from this, there is no problem of ethical problems in doing experiments on rats.
