___Are The Most Commonly Used Species For Animal Research

Since the advancements in medicine animals have been used in laboratories for research purposes but what is the most commonly used species for animal research?

________ Are The Most Commonly Used Species For Animal Research.



Mice and rats make up approximately 95% of all laboratory research animals for a variety of reasons. Their small size, short reproductive cycle, mild temperament, and docile nature make them an ideal choice. Besides this, their anatomy, biology,  genetics, and physiology also contribute to better research options.

What Is The Most Commonly Used Species For Psychological Research Using Animal Subjects?


Animals have been good research subjects for many reasons. The most important being their biological resemblance to humans. This makes them susceptible to similar psychological health problems as humans face.

Non-human primates, rats, mice, dogs, cats, and other rodents are most commonly used for psychological research as well as for behavioral therapy.

What Is The Biggest Reason We Use Animals In Research?

Have you wondered how researchers decide which species of animal to use for an experiment?

Researchers use animals for one main reason and that is their biological resemblance to humans. Animals also face similar health concerns, and due to their shorter lifespans, several generations can be studied in a short time.

As far as deciding which species of animal is suitable for the research, researchers decide which specific goals need to be met from the experiment, their knowledge about the human species, and how the condition compares to humans. 

What Species Is The Most Similar To Humans?

Back in 2005, researchers sequenced the chimp code. This code shed light on the fact that humans share 99% of their DNA with chimpanzees which makes them very similar to humans. Which animal shares the most traits with humans? Well definitely, they’re chimpanzees. 

Where Is Animal Testing Most Common?

When we source facts to see where are animals used in research, we can safely label China as the most common place for animal testing.

How Many Animals Are Used In Animal Testing?

As per the last estimate on animal research in 2015, approximately 192.1 million animals were used for scientific purposes. Out of this approximate figure, 207,724 dogs and 158,780 monkeys were put to use. 

What Animals Are Used For Animal Testing For Cosmetics?

Laboratories usually use rats, mice, guinea pigs, or rabbits that are bred for this purpose in special facilities. These animals spend their lives in dark cages, accessing only artificial light, tasteless food, and the confined space of a laboratory.

Which Animals Are Used For Clinical Trials?

Many animals from around the world are used for clinical trials. These include mice, rats, fish, rabbits, guinea pigs, hamsters, farm animals, cats, birds, dogs, mini pigs, monkeys, and chimpanzees.  These research animals are specially bred for this purpose.

Why Are Mice Used In Research?

Mice have many similarities when compared to humans in terms of anatomy, physiology, and genetics. The mouse genome is very similar to the human genome and this makes them effective while studying for human diseases. Mice are cheap, they are easy to look after, and their adults multiply rapidly.

Why Chimps Should Be Used For Research?

Chimps are highly valuable when it comes to studying the prevention of diseases because of their genetic similarity to humans. For many decades, chimps have been used for research. Humans match 99% of their DNA with them. This is why chimps are an ideal research subject, one which stands for humans but cannot use humans for this purpose.

Why Are Rabbits Used In Research?

Rabbits are widely used for research and experiments. They are practical and docile, their upkeep is cheap, and they reproduce quickly.  Besides this, they are used to produce serum antibodies and to model for diseases or biological systems.
