1. To human being
I have no reason to believe the religious doctrine of creation and so have to follow Darwinian theory of evolution. As we find coral like semi-living or semi-nonliving animals or materials even now, they provide justification to believe in creation of animal from material by evolution, though the first creature was lowly one-cell like creature. No doubt that creature received all his nourishment from one source to make his life easy. Instead of changing non-living to living time and again , the one-cell creature learned to divide itself to two and further. Sexual generation was not evolved at all. Step by step, the one-cell creature evolved to multi-cell one and source of nourishment became diverse and so started a harsh competition for food, water and air. Bi-sexual creatures fought for their mates too. They moved from place to place to fulfill these needs. Millions of creatures evolved in earth but needs are limited to air, water, food and mate and those too in time of physical need. Nature freely provides them what they need or they adjust to what nature provides them or they have to die out. Natural evolution has no other option.
Evolution to human being created a new dimension in the law of nature, i.e. human being refused to obey an all uses to nature. While earlier creatures were limited to natural needs, man fascinated anew luxury called desire. only highly developed mind could afford such a luxury.
Thus came the difference between man and other animals. He learnt to act and venture to fulfill his desire. A semi-living creature was converted to desiring animal by evolution and he dominated the earth, sometimes, even defying the nature.
2।Human Desire
After all, what is desire which boosts human activity? What is the difference between human need and desire?
Every living being needs some thing basic to sustain his life and to continue its activity. every living being efforts to acquire these items in daily basis and is satisfied if it gets them but human being does not do so and wants some thing more. This want beyond natural requirement is called desire. While human need is essential for his survival, desire is just strong longing for satisfaction and happiness or for some thing beyond natural need. Desire may very from time to time, place to place and person to person. A person without desire is a hermit living in the wild, who has neither future plan nor better expectations.
Desire motivates a person to have more and activates him to gain it. A tallest jiraffe can grab the leaves not above of its height. Two bulls can hit or push each other what their strength provides. Even the fastest leopard has limit in its speed but man has no such limits. He uses stairs, cranes, lifts to raise, uses bicycles, vehicles, horses, airplanes to gain speed and wrestlers cunningly bare hand or uses tools and arms to win. The superb brain acts both negatively and positively to fulfill his desire Capacity of strength of others animal can be measured in power units but that of man can not be. Other animals have measurable physical strength but mental creativity of man is un-measurable. And so is desire. Fulfillment of one desire creates another one and so on. Desire creates capacity, capacity fulfills action, action creates gain, gain brings satisfaction and raises affluence level where another desire rises automatically. The never ending circle of human activity moves like a spiral upward raising human knowledge and affluence. Human civilization is creation of revolving activity of desire.
___________ Desire __________

'Necessity is mother of invention' – says a proverb nut what a person may need if he is satisfied on what he has. Desire creates non-satisfaction or vice-versa. A person desires to be better than or superior to others. A bread earner demands loyalty and respect from family members. He desires superiority, efforts for it and gets it to earn respect and superiority. Thus we coe to conclusion: Animal needs are natural necessities for survival and desires are human necessities for prosperity.
