We have five sensory organs, nose for breathing,, ear for listening eyes for seeing, skin for touch-feeling, tongue for tasting .Out of these five organs who evolved first ? Did they evolve simultaneously at the same time?
I was watching animal planet in TV; some animals have two or three fingers while human has five; both in fore limbs and hind limbs; So it flashed in my mind that all these organs of living beings evolved gradually according to the necessity and influence of the environment.Who was the first among sensory organs to evolve first?.......
I think that skin which. is the covering of body is the first one to evolve . Skin was full of pores or outlet which was the source of breathing, hearing, seeing, tasting . About 5oo to 6oo million years ago earthworm burrowed on the seafloor ;may be they are the key to the evolution of living kingdom.
Darwin noted earthworm are extremely sensitive to vibrations. Fossil is the common ancestor of all worms .Earthworms are the best tiller of earth.Their body had sects,if a portion of it is cut ,it is replaced by new growth . Skin gave proxy to all other senses; even procreation.
In course of time hearing organ came out ; as division of labour enables one to be better able and efficient; so after hearing, breathing organ evolved Most probably, hearing and breathing evolved simultaneously at the same time; then mouth came up to consume food.. Eyes were the latest organ to evolve . Eyes and ear performed combined the job of brain .
So skin is the source or prime powerhouse to the origin of ear to hear, nose to breath, eyes to see, and mouth to eat& taste . As soon as the eyes opened the "data' ' informations "started to collect in the storage box which is known later as brain .
Eyes are the first source of all disaster! In conversation we often use that 'at last eyes opened', which means awareness or the agility of brain to catch up experiences . "Eyes opened "declares the dominance of sensory organs over the depth of inner SPIRIT OR soul.
Power of sight created sensual desire of choice for liking & disliking. The prime relationship between all living organisms was food ( either eat or to be eaten ) and sex ; Before the origin of eyes whatever comes within the range of living organisms they ate and also they mate without any discrimination. Now as they learnt to move they chased after their choice of food and sex; This movement created heat and electricity in body.
Eyes enabled them to differentiate which one gives more satisfaction to the senses .All these happened in a time when the world was occupied mostly with water. The food charged heat and electricity which in turn created sex in body .At the very beginning there was no male or female sex. Each and every singular body contained the double sex in themselves. The best example of our known worm or insect is earthworm. Many. other lower- living milli-meter sized small insects also are able to reproduce . Fish of deep ocean were able to produce male part from their own body when they felt to reproduce . So life proliferated from singularity in the beginning .
Plants who are our primitive ancestors also provide the same truth.
A childhood experience about "Lojjaboti lata"(=a creeper plant), flashes in my mind as I am writing. I and my friend hid ourselves , while playing ,behind a Calvert which was covered by green creeper with superfine leaves. My friend said ,"Do you notice the fun? As She touched the creeper all the leaves of the creeper folded as if they fell into sudden sleep . With surprise I started to touch the all parts of the creeper to make the leaves sleep .I was surprised and felt it more exciting than the game of hide and seek. My friend whispered this is known as 'touch-me-not"creeper. But the leaves awake within short period .That was a great fun to learn about plant .
With the help of ear, eyes formed the 'first'. basement of brain. Ear, nose, throat are so closely related that they respond to one another; they are accessaries of brain . In medical science we take appointment to ENT doc for the related problem in any one of them. Pituitary gland is very important ; It is a pea-sized organ, housed in the bony structure at the base of brain ; it is the master gland ; it drive the other glands to release hormones in all vital parts like brain ,skin, energy , vision, blood pressure, reproductive organs etc.In one word it is the power house of a body.
We take little care about our ear which is the main source of knowledge .In acupuncture treatment the doctor treated in this area to treat any part of the body. It is same as. the main switch -box suppling electricity connected to the whole nervous system of our body.
Animals use the five sensory organs differently according to their need and ability. Say for instance: bats use their ears to see; moles use their nose to dig mud to shelter while the elephants use their. trunk/nose for bath , snakes use their mouth both to breath and swallow; chamelions have fantastic sight and capacity to hide by camofladging; scents and color of flowers attract the butterfly; Sometime they use scent as trap .They use the sense-organ to protect themselves from predators; animals with .whiskers around mouth work like antenna ;The hair/ fur of polar bear in the arctic region conserve heat of the sun like optic fibre wire to keep the body warm in cold.....Dogs'. skin don't sweat ;they gasp and drooling tongue keep their body cool.
The story of the Mughal emperor Akbar's experiment is suitable example to prove the importance of ear. Akbar himself was illiterate but he was no less than a pandit ; He learnt only by listening from the wise pandit .Once there was dispute among the people about language : Which language was god-given and noblest of all.
To solve the problem, Akbar the Great ordered his minister to collect 10 babies of six months from the parents who have unique linguistic difference and. to keep these ten babies in ten different sound proof chambers under proper baby-care. Only the ten deaf and dumb care-takers. were appointed to take care for. those babies. These babies belong to the parents who followed the language of Urdu ,Farsi, Sanskrit , Pali, Maithily , brojobuli and some local ,even tribal language. When the babies became five years old. they were presented in the royal court.
The court was overcrowded of the mass with high pitch of excitement . To their disappointment it was found that all. those. ten babies were deaf and dumb ; none of them could speak in any language at all .Thus the emperor convinced the common people that no language could claim superior to other as "God's language". All languages were equal.The baby learn that language which they listen from the parent or in environment ; if they hear nothing as sound of language from the beginning of birth ,they would learn nothing .
Though. some. people were not happy , but they couldn't argue Thus Akbar the Great solved the dispute of language peacefully . He was able to run on with the same "FARSI". as court language of the country.He reigned from 1556 to 1605 as most popular Mughal emperor, in spite of being illiterate but wise only by listening. He wrote a book named "Akbar-E-Nama" to compromise the conflict between Hindu-ism and Islamist.
