Difference Between Humans and Animals

From a biological perspective, humans are animals, as we share quite a few anatomical and physiological similarities with them. However, enough differences do exist to separate us from other animals. We shall explore these differences between human and animals.

Difference Between Humans and Animals

Following are some of the important differences between humans and animals:


Humans belong to the species “Homo sapiens”

Animals cover a number of species.

Humans are omnivores.

Most animals are either herbivores or carnivores. Animals like bears are omnivores.
The average human brain weighs 1.2 kgs

Brain size varies across species – with the largest ones weighing in at 6.92 kgs (blue whales) and the smallest ever belonging to the ragworm, measuring just under 180 micrometres across (equal to the width of a human hair)

Just like animals, humans are also driven by instincts. However, we can also reason.

Animals are primarily driven by instincts.
Modern humans are bipedal.

Most vertebrates are quadrupedal, i.e., they walk on four legs. Few animals such as snakes crawl. The aquatic organisms have fins to swim.

Humans have “true language” to express themselves.

Animals communicate with each other; however, none have the complexity nor

the expressiveness of the human language.

Thus, we see how humans and animals are different from each other.

Anatomically, humans are quite similar to most other animals as we share a common body structure. For instance, the hand of a bat and the hand of a human are considered homologous as a result of shared ancestry. Explore more details here: Homologous and Analogous Structures
