A FULLY OPPOSABLE THUMB GIVES THE HUMAN HAND ITS UNIQUE POWER GRIP AND PRECISION GRIP
WHAT IS CREATION ? :
I would like to define creation as the process by which products are created with degrees of variations amongst them and they would appear to be different even when they are related to each other. This variation gives the product of creation an identity, individuality, a sense of uniqueness, and an attribute of distinctiveness. For example, humans and chimpanzees share almost identical genomes, but we are different. This variation is present between different species and amongst members of the same species. Hence, creation could be stated as a process which institutes differences between apparently similar objects and makes them unique and distinct. In the fields of arts, music, literature and others, originality is an attribute of creativity. In creating man, the Creator has displayed His powers of creativity and we can always distinguish one individual from another individual.
WHAT IS THE IDENTITY OF MAN ? :
Man is classified as Homo sapiens sapiens- i.e. the sapiens variety of the species Homo sapiens. Modern humans have delicate skeletons. Their skulls are more rounded with a mean cranial capacity of about 1,350 cubic centimetres(82 cubic inches). Their brow ridges generally protrude much less and they have a vertical forehead. The back part of the skulls are more rounded and rarely display the occipital buns found on the back of Neanderthal skulls. Man has jaws and teeth of reduced size, the nose and chin are prominent or projecting. The relatively high foreheads are indicative of both qualitative and quantitative development of the brain. Those areas of the brain concerned with vision, muscular coordination, memory, learning, and communication have especially shown development. A large and complicated brain( which may be called a superior brain), the stereoscopic vision and a corresponding reduction of the sense of smell, the upright posture and the supremely flexible hands are some of our important features. The pelvis and the legs are designed to support weight, help the bipedal propulsion of the body in the erect position, while the feet and toes have lost the prehensility characteristic of the Primates in general. We have been identifying individuals for a long time now. We use several methods to establish the identity. Photos, fingerprints, dental records, iris scans, and DNA are some of the tools used in the identification process.
THE EVIDENCE OF PRECISION GRIP :
The modern humans are different from all other species including other species which have similar features of the genus HOMO.
Humans use their flexible, grasping hands to explore and utilize the environment in unique ways. A fully opposable thumb and fingers makes the hands capable of both power and precision grips and gives remarkable manipulative abilities. Human hands can skillfully fabricate tools and produce art and sculpture. Man has not only invented tools like needles, he has the manipulative ability to thread a needle and to sew clothes using hides and other materials. The ability to hold a brush and draw paintings sets man apart from other ancestral types which used stone tools and used fire for cooking, for warmth and in hunting.
Prehistoric art is a relatively recent development; it first appeared during the Upper Paleolithic Period, the last division of the Old Stone Age. The first cave paintings were discovered in Spain and France belong to the Upper Paleolithic Period(c. 30,000 – c. 10,000 BC ). These are associated with the remains of CRO-MAGNON MAN who appeared in Europe about 35,000 years ago. So far, no direct evidence of Neanderthal art has been found. The CRO-MAGNON MAN would have looked like the present day European man but the CRO-MAGNON had a relatively larger cranial capacity( upto 1590 cubic centimeters ) and a broader face. The culture based upon hunting and gathering reached its peak of development about 12,000 years ago. Technical innovations included tools made of bone and ivory, clothing sewn together and a system of reckoning time by the Sun and the Moon. About 10,000 years ago, during the Mesolithic Period, man had invented new weapons such as the bow and arrow and started using ingenious traps, snares and nets to exploit the natural resources.
THE UNIQUENESS ABOUT THE USE OF HANDS :
Man uses his hands not only in the performance of non-locomotor activities but also to express his thoughts, ideas, feelings, moods and emotions. We differ from all other species in the manner with which we use our hands to communicate with others. We use our hands to greet others, to show love and affection,to provide comfort and to perform acts of kindness and compassion, to demonstrate anger and displeasure or frustration, to display an obedient and respectful behavior, to derive psycho-sexual gratification, and to communicate in various non-verbal manners. The unique ways in which man uses his hands has produced cultural icons. In India, people use hands to greet others and the greeting is known as ‘NAMASKAR’ or ‘NAMASTE’. Indians greet and worship their Gods and everything that He had created in the same manner and with the same greeting of ‘NAMASKAR’.
If there are over six billion human beings on this planet, I could easily demonstrate that there are over six billion individual variations by simply testing the use of the precision grip by each individual. These differences are important and give us our identity and this is possible because each one of us is created in a very special manner.
