Meaning of Man's Uniqueness:

The uniqueness of man can be defined as that which makes man distinct from every other animal and living organism. In this regard, human beings are considered as animals according to science. However, humans are distinctively higher animals when compared to other animals.

Please read on the general characteristics of living organisms here.

Under the classification of living organisms, humans belong to an order termed primates and thus share the same characteristics (as primates). In addition to these features, they also have their unique characteristics.

Please read on primates and their characteristics here.

Note: Man as used in this article will refer to all human beings.


Unique Characteristics of Man

The unique characteristics of man can simply be attributed to those features that are exclusively present on humans. These unique features or characteristics include:

1. Highly developed brain

Among all organisms in the universe, the human brain is the most developed.

The highly developed brain of humans is the biggest factor that makes man unique from every other organism on earth.

Below is an image of the human brain showing the gyri and sulci respectively:
Human Brain Gyri and Sulci - Len Academy

Please read on an introduction to the human brain here.

According to research, the more folds a brain has, the more intelligent the organism possessing it will become. To this end, humans have brains with the greatest number of folds (or bumps) called gyri and grooves (or indentations) called sulci.

You can attempt Len Academy questions on various subjects here.


2. Uprightness and Bipedalism

Bipedalism is a form of locomotion whereby an organism move by means of its two hind limbs. Animals that move in this manner via their two feet are referred to as biped.

Humans are the only primates that can efficiently move in an upright manner and with their two feet. Although apes and baboons can exhibit a biped movement in an upright manner, they expend more energy and as a result, such biped movement will not be their preferred choice of locomotion.

The choice of movement in baboons is via brachiation. Think of brachiation as a specialized form of movement whereby animals swing from one tree branch (or projection) to another.

Brachiation may also be referred to as arm swinging.


3. Ability to advance in language and speech

The presence of mouth, tongue, lips and larynx (or voice box) in connection with the brain is responsible for human advancement in speech and language.

Humans are the only animals that can speak a variety of languages while also manipulating their voice into music production. This feature of voice manipulation makes man unique from all other animals.

Please read on reputation and how to build a good reputation here.


4. Great flexibility of the shoulder Joint

The anatomical alignment of the muscles and bones of the shoulders in humans is only unique to humans.

Please read on all bones of the human skeleton here.

Unlike monkeys and chimpanzee whose shoulders are best suited for hanging on trees, the human shoulder (which is the most flexible joint in the human body) is better adapted for throwing, hunting, catching, shooting and a complete movement of the upper limbs. This advancement in structure and function of the human shoulders have given them an excellent survival and building skills.

Man is the greatest hunter on earth and one attribute to this fact is via the great flexibility and composition of their shoulder joint and muscles.

You can read various amazing facts in biology here.


5. Nature of hands and thumbs

Although humans and other primates have got opposable thumbs, both are not the same. The difference between both thumbs (humans and other primates) is due to it's exact size and location.

Unlike other primates, humans have smaller hands with an excellently positioned thumb. In addition to this, all the fingers (in humans) are richly innervated (that is; supplied with nerve), even to their tips. This is the very reason why humans can uniquely engage in fine motor skills like sewing, writing and drawing.

You can read on idioms here.


6. Sweat and Glands

Humans are not the only animals that possess sweat glands but the fact remains that theirs are unique from other animals, including apes and horses. The difference in the sweat glands of humans is as result of its composition.

The sweat glands of humans secrete mainly water, in addition to salt: that is; sodium ion (Na+) and chlorine ion (Cl-).

Based on these secretions, the sweat of humans is similar to a salt solution.

Please read on salts and types of salt in chemistry here.

The sweat glands of other animals comprises of a mixture of water, lipids, fats and protein. In short, these animals sweat differently from humans.

You can read more on mixtures here.


7. Intelligence

Intelligence may be defined as the ability to apply knowledge into manipulating one's environment to their benefit. It can also be defined as a general cognitive problem-solving skills. You can think of it (intelligence) as the 'skilled use of reason'.

Please read on intelligent and motivational quotes for students here.

We see the application of human intelligence in the development of the internet, automobiles, spaceships, buildings, computers and so on.

You can read on the internet of things here.

Except humans, no other animal can achieve these feats of intelligence. Human intelligence changes over time with age. Also, it can be inherited.

Intelligence Quotient (IQ) is a score derived from a set of standardized tests developed to measure a person's cognitive abilities in relation to their age group.

IQ may also be defined as the ratio of mental age (MA) to chronological age (CA) multiplied by 100.

Please read on what students are expected to know here.

Below are some formulas pertaining Intelligence Quotient:

IQ = MA x 100 ÷ CA

MA = Mental age

CA = Chronological age

IQ above 100 = Brilliance

IQ that equals 100 = Average

IQ below 100 = Below Average

Amazing facts in Basic Science

Cranberries - Len Academy

Ripe cranberries will bounce like a ball. For this reason, they are nicknamed 'bounceberries'. They will also float in water

Tomatoes and Avocados are fruits, not vegetables

Sweat in itself doesn't smell. The smell that accompanies sweat is actually caused by the presence of bacteria on your skin. This bacteria breaks the sweat coming out of your sweat pores down into acids, thus making it smell.

Deodorants contains alcohol and are antibacterial. They work by killing the bacteria that makes sweat smell

Chewing aspirin during a heart attack may be a life saver. This is true because the drug inhibits platelets from forming a clot that can block an artery of the heart, thus stopping a heart attack

The kneecaps of newly born babies are not made of bone. Rather, they are little bits of cartilage which ossifies (turns from cartilages to bone) from age 2 to 6

Ice cubes - Len Academy

Ice cubes made with fresh water are white in color while those made with boiled water are crystal clear

Cats are unable to taste sweet things

Apples float on water. Other fruits that float on water include lemons, bananas, pears, and oranges

Rain water is said to be pure because it's colorless, odourless and tasteless. Interestingly, it also contains vitamin B12.

Vitamin B12 is an important nutrient that keeps the blood cells and neurones healthy. It also assist in building the DNA (a genetic material present in the cell's nucleus). Vitamin B12 also aid in the prevention of megaloblastic anemia which makes people weak and tired

Rasceta is the name given to the lines on your palm

Disaccharides are composed of two monosaccharides joined together; thus are also referred to as double sugars.

Disaccharides are often added as sweeteners to food; for instance, the table sugar called sucrose is a disaccharide often used by us to sweeten our tea.

Maltose is another disaccharide used as an ingredient for making malt drinks, chocolates and candies.

The breast milk contains the disaccharide -> lactose.

Lactose is very vital for the normal growth and development of infants.

In adults, disaccharides are non essential nutrients. This implies that we can live without them as adults.

Below is a summary of monosaccharides that make up disaccharides (double sugars).

  • Maltose = Glucose + Glucose

  • Lactose = Glucose + Galactose

  • Sucrose = Glucose + Fructose

Other examples of disaccharides include trehalulose and isomaltulose
