Why humans are also animals by Jitu Das

Click here for :-

I am writing this post mainly for those people who does not think that humans are also animals. This post is for those who believe humans are created by god in his own image.

This post is a simplification of the idea that all animals and plants possess atleast one cell and genetic material. In case of us, we are animals. But what is the link between humans with the other animals ? All animal atleast have one cell and within that cell have a nucleus, nucleus, within nucleus a cell have chromosomes, chromosomes are made of DNA.

 DNA is made of deoxy ribose, nitrogenous base and a phosphate molecule. This DNA is the genetic material or the information that is the commonest compound present in all life being except some virus. DNA has the same function in all animals and plants ie. to help the cell to devide, create new proteins, to carry the genetic material from one generation of any life being to its next generation. That is how we all life beings are connected.

Whenever I see the natural landscape of the world. I feel so much pure joy that makes my day. When you appreciate how vast and beautiful our world is, you transcend to inner peace. When you see the beauty of the world and how it works. You know then how great nature is and we are what we are because of the nature.

Water, fire, wind and soil are among the most affecting part of nature.
The cell is the basic structural, functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing, and are often called the “building blocks of life”.

Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants and animals). Every animal and plant has at leat one cell. The cells are may be different in different animals,but properties and constituents of cell of every animals are same including human.Cells consist of a protoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.

The 75 % of our planet earth is water. Just like that avg. 57 % of total weight of a human being is water. You can not deny that because every cell of our body is made of mainly protoplasm and protoplasm has been defined as the material basis of life. Protoplasm is made up mainly of oxygen, carbon, hydrogen and nitrogen, which make up 95 % weight of the body. Water is the main inorganic substance and it varies from 5 % to 90 % in different tissues.

So, we have water( H20) in our every cell, in the cells of the brain that we call neurons, the neurons by which we think, we feel happiness, anger, jealousy, shyness, peace, anxiety, stress, we remember, create, solve and store information and memories, we dream by our brains, how strange it seems when my brain is thinking about my brain. 

Brain is the only subject in the universe that wants to understand itself. That is what makes human being so advanced than the other animals. But that does not mean we are not animals, we are also animals but advanced. All animals have at least one cell, We know we have cells, so we are also animals

We are mammals. Every animal including us have cells and except bacteria, there is a nucleus in the cells of all animals and inside the nucleus there are chromosomes. We human have 46 chromosomes in our every cell and the Chimpanzee’s have 48 chromosomes. The chromosomes are made of DNA.

The DNA is present in the cells of all plants, animals,prokaryotes and in a number of viruses. The DNA ( deoxy ribo nuclic acid) is a nucleic acid made up of oxygen,nitrogen, phosphorus, hydrogen. The DNA creates the protein in our body. The cell division by which a 3 kg baby becomes a man of 70 kg and of 70 kg weight 45 kg will be water( H20). It is the truth of our body. The DNA is the mastermind of the cells, the DNA is what carries the traits of parents to their children and thus the characters of father or mother is seen in their children.
Except some viruses,DNA is found in all animals and DNA plays the same role of replicating itself helping in cell division and passing the characters of an individual from one generation to next generation.

Sometime the DNA recombine and create a new character and that is called mutation. Mutation or change of original character is also caused by adaptation with the surrounding environment. That is where again nature plays a great role in shaping the physical and anatomical characters of the plants and animals including human being, ie. Us.

We are what we are because of our surrounding environment. In south africa, people are black because the sun rays fall their in 90 degree which means directly, In my country India, sun rays falls in 45 degree, that is why India is a subtropical country. In Europe people are white it is because of the climate. We are also what we eat. The food also creates a huge difference.

In the big picture, all the animals are connected to each other. Animals depends on the plants and the plants depend on the Sun. Sun depends on its hydrogen which burns and create helium and light and heat. Without the sun we are nothing and without the hydrogen, sun is nothing. So, great scientist Newton was right. Everything in the universe is connected to each other. Have a good night.
