Humans are thought to have been evolved from animals as per the theory of evolution.
But interestingly, humans are different than animals in many ways.
However, the theory also holds good in the sense that their body organization is similar to humans.
This is the reason why new drug molecules are tested on animals before making tests on humans.
Besides, animals also have emotions and senses like humans.
They even communicate with each other, live in a group or as a society like humans.
10 points on how are humans different from animals.
Human advantages over animals make them quite different from animals.
|Talk||Humans have a wonderful ability to communicate by way of talking, use of words and speech.||Animals can’t talk but communicate by few sounds.|
|Laugh||Laugh is a virtue by which humans express happness. Even a new born baby will laugh without others guidance||Animals cannot laugh.They cannot laugh as way to express happiness but do it by other ways.|
|Communication||Humans coomunicate by words, speech, wrting, body language, body movements, facial expressions, signals etc.||Animals communcate only by few sounds, signals and body language. But still it is less effective than humans.|
|Limbs||Humans have two legs to walk and other two i.e. hands for other purposes.||Animals have all the limbs meant for walking. Some of them even have many limbs.|
|Social life||Humans always stay in groups and as a society.||Except few animals like Ants, Bees, Elephants etc. many animals live in isolation.|
|Evolved senses.||Humans have highly evolved sense organs. They differentiate colors, tastes, fragrances etc.||Animals also have these senses but are less developed. Many do not recognize individual colors. Some of them like insects have compound eyes that have multiple visions.|
|Brain||Human bran is well developed and has many folding which is indicative of judgement, thought, memory etc.||Animals brain is less developed and hence lack better judgment, memory and even efficient thoughts.|
|Memory||Humans have a better memory than animals||memory of animals varies and higher animals have better but not equivalent to humans.|
|Psychology||Human psychology is quite evolved due to the ability to think, imagine and memorize. This is useful but sometimes harmful too.||Animals psychology is quite limited and are less prone to modifications.|
|Life span||Humans have more life span than many animals.||Many animals have lesser life span from days, months to few year with exception of tortoise, elephants which have more than man.|
|Body flexibility||The human body is quite flexible than animals. One can bend in different ways and move limbs as freely as required. This ability helps him perform actions like lifting, throwing, scratching, carrying with ease compared to other animals.||Animal’s body is also flexible but is minimalistic in comparison.|
|Diseases||Humans suffer from many diseases due to lifestyle and habits.||Animals comparatively suffer from less number of diseases.|
Thus above are some of the points on what makes humans different from animals.
But in terms of biology, the anatomy and physiology of humans are quite similar to animals.
So scientifically, humans are classified as animals rather than plants.
Their organs and organ systems are quite similar to humans, due to which we test many new drugs on them.
Many animal extracts or biological products like heparin and insulin can be used in humans as replacement therapy.
