Difference Between Humans and Animals

Scientists have proved that humans have descended directly from animals. The evolution of man is almost the same as animals. In that sense, there are several similarities between humans and animals. Nonetheless, several characteristics of humans separate us from the rest of the animals on this planet. 

The main qualities that make humans a refined animal are those of logic, evaluation and language. 

Let us Proceed with the Key Difference Between Humans and Animals. 

Key Points of Difference

  • Origin

The species humans belong from is “Homo Sapiens”.

In the case of animals, there are various species which are involved. 

  • Food Habits

Humans are typically omnivores. 

Animals, on the other hand, are herbivores or carnivores, and occasionally both. For example, Raccoons are omnivores. 

  • Brain 

Humans have a complex nervous system. The brain is an integral part of it. The size of the human brain is almost 1.2 kg that is bigger than any average animal.

Most animals have a smaller size of brain. Among exceptions, bottlenose dolphins have bigger brains than humans. It is 1.6 kg. Interestingly, jellyfishes do not have any brain. 

  • Mental Abilities 

The power of logical thinking and rationality make humans superior to other animals. Humans have the ability to think critically and act accordingly. Also, they can express our emotions (happiness, sadness, excitement, etc.).

Very few animals are capable of expressing their emotions. Also, they are not the same as that of humans. This is one of the most striking differences between humans and animals. 

  • Digestive System 

While humans possess monogastric digestive systems, some animals have a ruminant digestive system. For example, sheep have a four-chambered stomach. However, their digestion is not as efficient as humans.  

  • Form of Locomotion 

Humans walk upright and on two legs. Therefore they are called bipedal. 

Most animals walk on four legs, and they are called quadrupedal. Also, some animals have different kinds of locomotion. For example, crocodiles crawl on land. 

  • Mode of Communication 

Humans are the only species on earth that has natural language processing ability. Their voice system is different from animals. Also, they communicate through words. 

Most animals communicate with each other on a basic level. However, some birds like parrots and other animals can imitate humans and subsequently talk like them. Notably, they are neither as perfect as humans, nor do they understand them. 

  • Survival strategies 

Humans with their advanced mental ability and curiosity can turn any environment in their favour.

Animals are different from humans in the sense that they either adapt to their existing environment or die. Also, they consume only for their survival. 

  • Endangerment 

Humans have invented science and made several ways so that they live on the planet for years. 

Some animal species can become extinct as they are dependent only on nature. 

  • Nature 

The biggest difference between humans and animals is that humans are driven by reason and logic. They can engage in intellectual activities.

Animals, on the other hand, are completely driven by instincts.

These pointers above are the fundamental differences that separates animals from humans.
