[Biology Class Notes] on Difference Between Humans and Animals Pdf

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.  According to the definition, an animal is a living thing other than humans that feeds and has sense organs, a neurological system, and the ability to move. The vast majority of species are classified as animals. Humans are bipedal species that belong to the Homo Sapiens genus. Humans walk around utilizing their two back limbs in this manner.

Humans:

A human being, or human, is any member of the mammalian species Homo sapiens, a group of ground-dwelling, tailless primates found all over the world that is distinguished by bipedalism, the ability to speak and communicate, and an erect body carriage that frees the hands for manipulating items. Humans, unlike any other species, communicate a vast lot of cultural information through the use of language. Many animals, including most invertebrates, have no link with their parents because they die before they are hatched and hence do not pass information to their offspring. Humans, on the other hand, create monogamous pair bonds and provide significant parental care to their children, raising them in households where both parents teach them.

Animals: 

Any of a group of multicellular eukaryotic organisms that belongs to the kingdom Animalia (i.e., as distinct from bacteria, their deoxyribonucleic acid, or DNA, is contained in a membrane-bound nucleus). They are assumed to have developed separately from unicellular eukaryotes. Animals have essential morphological and physiological differences from the two other kingdoms of multicellular eukaryotes, plants (Plantae) and fungi (Mycota). This is largely due to the development of muscles and, as a result, mobility in animals, a trait that has aided the development of tissues and organ systems.

Muscles and the movement they provide are characteristics of members of the animal kingdom. Mobility has a significant impact on an organism’s ability to gather nutrients for growth and reproduction. Animals move to feed on other living species in one form or another, but some absorb dead organic matter or even photosynthesize by housing symbiotic algae. When it comes to separating animals from the other two multicellular kingdoms, the type of feeding is less important than the sort of movement.

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

 

Difference Between Human and Animal:

Point of Difference

Human

Animal

Origin

The species humans belong to is “Homo Sapiens”.

In the case of animals, there are various species that 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, which is bigger than any average animal.

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

Mental Abilities 

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 humans. This is one of the most striking differences between humans and animals. 

Digestive System 

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 quadrupedalism. 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. 

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. 

Survival strategies

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

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 

Humans are driven by reason and logic.

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

Multiple Choice Questions

1. ___________ has tube feet. 

  1. Jellyfish


  2. Cuttlefish

  3. Starfish

  4. Crayfish

Ans: (A)

Explanation: Echinoderms’ locomotory organs are tube feet. Jellyfish swim by

expanding and contracting their bell-shaped bodies radially to push water behind them.

2. Earthworms have __________ pairs of hearts.

  1. 1

  2. 2

  3. 3

  4. 4

Ans: (D)

Explanation: The blood vascular system of an earthworm is closed, with blood flowing to the heart and blood vessels. The tubular hearts of an earthworm are divided into four pairs. The walls of these hearts are thick, they are enlarged, and they have valves. The dorsal and ventral blood vessels are connected by these lateral hearts.

3. What is common between kiwi, penguins, and ostrich?

  1. Running bird

  2. Flightless bird

  3. Migratory bird

  4. Four-toed bird

Ans: (B)

Explanation: All of these birds have one thing in common: they are flightless. In general, all birds have the same muscle and bone structure, however, flightless birds have a different structure.

4. Left systemic arch is not present in

  1. Reptiles

  2. Mammals

  3. Birds

  4. Both mammals and reptiles

Ans:  (C)

Explanation: Archetypal system The fourth aortic arch of a tetrapod embryo, which becomes the main source of blood supply to all sections of the body except the head as an adult. Adults in birds only have the right arch, while adults in mammals only have the left arch.

5. Which is not an amphibian?

  1. Toad

  2. Salamander

  3. Tortoise

  4. Frog

Ans: (C)

Explanation: Tortoises are not amphibians; they are reptiles. A tortoise can live on land or in water, but the shell protects the tortoise’s body, which is covered dorsally by the carapace and ventrally by the plastron. The existence of protective shells is not a distinguishing characteristic of amphibians.

Answer if these following statements are true or false:

  • Ladybugs are carnivores.

  • Corals have no brain

  • Spiders are herbivores

  • A whale is a mammal

  • Snakes can hear. 

Answers:       

  1. True: They also eat fruit flies, thrips, and mites, which are all dangerous insects. Although not all ladybugs are carnivores, those that are are beneficial to gardeners since they do not harm crops while feeding their appetites.

  2. True: Brain corals, which have a cerebral appearance but no brains, can grow to be six feet tall and live for up to 900 years! Brain corals are found in the Caribbean, Atlantic, and Pacific Oceans and exhibit Meandroid tissue integration.

  3. False: Though the vast majority of spiders are carnivorous, a few species, mostly jumping spiders, supplement their diet with plant stuff such as sap, honey, and pollen.

  4. True: Whales are mammals because they give birth to live offspring, have fur (albeit scarce on their bodies), have lungs and can breathe air, and produce milk for their young.

  5. False: Snakes lack an eardrum but have fully developed inner ear components. Instead, when they crawl, their inner ear is attached directly to their jawbone, which rests on the ground.
