The biological goal of the existence of every organism becomes understandable when we realize that it acts as a protector of genes worn in it, which must ensure that they move into the child's body before the caregiver himself becomes old and can not function properly.

Every animal has a particular purpose on the planet. We may not like some of those purposes, but they're all necessary for us to exist.

The purpose of life is to stay alive. Watch any animal in nature — all it tries to do is stay alive. It doesn't care about beliefs or philosophy. Whenever any animal's behavior puts it out of touch with the realities of its existence, it becomes exinct.

All the vital mechanisms, varied as they are, have only one object, that of preserving constant the conditions of life in the internal environment.

When I talk of the purpose of life, I am thinking not only of human life, but of all life on Earth and of the life which must exist upon other planets throughout the universe. It is only of life on Earth, however, that one can speak with any certainty. It seems to me that all life on Earth, the sum total of life upon the Earth, has purpose. If the means were available, we could trace our ancestry — yours and mine — back to the first blob of life-like material that came into being on the planet. The same thing could be done for the spider that spun his web in the grass, and of the grass in which the web was spun, the bird sitting in the tree and the tree in which he sits, the toad waiting for the fly beneath the bush, and for the fly and bush. We are all genetic brothers. The chain of life, tracing back to that primordial day of life's beginning, is unbroken...

Self-preservation is the central aim of all life-activities.

You know . . . If you think about the very nature of life — I mean, in the very beginning, the development of the first cell divided into two cells — the sole purpose of life has been to pass on what was learned. There was no higher purpose. So if you’re asking me what to do with all this knowledge you’re accumulating, I say . . Pass it on.

Like every living thing its prime characteristic is a blind, unreasoned instinct to survive.

Well, for once in my life, I not only know why I’m here, at this place, I finally know why I exist. I’ve always wondered why I was so odd. What possible evolutionary purpose could a person like me serve? No kids. Focused on my own experiences... This is my purpose. This has always been the purpose of people like us. We blaze trails. We chart oceans. We push back frontiers. Without us, humanity slowly dies.

I’m just an information processor like any other living thing.

The Purpose of Life is Life itself it

Molecular biology has also shown that the basic design of the cell system is essentially the same in all living systems on earth from bacteria to mammals. In all organisms the roles of DNA, mRNA and protein are identical. The meaning of the genetic code is also virtually identical in all cells. The size, structure and component design of the protein synthetic machinery is practically the same in all cells. In terms of their basic biochemical design, therefore no living system can be thought of as being primitive or ancestral with respect to any other system, nor is there the slightest empirical hint of an evolutionary sequence among all the incredibly diverse cells on earth.

All forms of life are related to each other, and the basic mechanisms that drive all of them are the same.

The soul is the same in all living creatures, although the body of each is different.
