You need to understand:- "In the above form/sense we are immortal, otherwise not/can't. However, we can think of just "Longevity" in our present form. Can we say that " Longevity" or " great regeneration capabilities" is/can be just effected by the environmental effects surrounding us?" Means, we can't be immortal in our present human body form. Longevity of our present human body form can possibily be improved by improving environment--which may ultimetely leads to improving the body environment & so the life span. Opposite can effect just opposite.
In the long run even the universe will not last forever, when you live to see then end of the universe where do you go afterwards? Where do you get energy from? Sorry but all things in this universe and these set of physics requires that nothing last forever, entropy wins. Perhaps we could run off to another dimension where infinite existence is possible and thermodynamics is non-existent. As for immortalizing the human body, fat chance, aging is a multi-cause process, to defeat it would require some serious re-designing of the human form, or at the very least a constant fresh replacement of organs and bodies and a cybernetic brain.
Let us first assume a logical model of evolution. I assume as under:- Basic Energy>* Matter+some differantiated energy> Sub-atomic particles>atoms>differanciated atoms>molecules>differanciated molecules>cells>>**differanciated cells>>multi cellular livings>>differanciated multi cellular livings>>Living body>>differantiated living bodies>>plants,birds & animals>>differant species of plants, birds & animals>>higher animals & other livings>>all livings: humans,animals,birds,plants etc.>>>***degradation of livings..... >*good/creative/positive environmental effects. >>**medium/some postive/maintainable environmental effects. >>>*** Bad/destructive/negative environmental effects. Is it somewhat ok? Big Bang cycle/theory may somewhat indicate creative, maintance & destructive phases of evolution.
Why can't we change? It is adaption/nurture not our 'nature'. As we have adapted it, by doing just opposite & equally we can also change it (possible but if we will do or not, can't say Please Register or Log in to view the hidden image! )
It is ok that changing/removing all environmental effects may mean stoping being human. But can't we improve environment even being human by changing some destructive environmental effect? Can you assess that environmental changes are pH(body's environmet) changes related & by making changes in pH imbalances, we may probably improve environmental bad effects?
Modren civilization un-naturalities, hereditory diseases etc. I again feel that you can assess it. Just assess it.
it seems modern civilization has an overall good effect on the human condition. Hereditory diseases are not enviromental.
Just feel: "Survival of the fittest" is the best living being. In this sense compare highest/higher lived & fittest ones, previously(with less unnaturalities in environment) with the present ones. Just compare the qualities of the 'fittest ones' not the quantities. In nature, best fittest ones may be entitled to continue or carry on, other weak/unfit one may just spread & carry on-- weaknesses. But heriditory diseases can be due to environmental effects-- an *adaptation of changed environment. It can be just passing a signal of ' environment type' to next generations unabling those to prepare/keep updated for it. *Adaptation: 1 : the act or process of adapting : the state of being adapted 2 : adjustment to environmental conditions: as a : adjustment of a sense organ to the intensity or quality of stimulation b : modification of an organism or its parts that makes it more fit for existence under the conditions of its environment
Survival of the fittest is a term coined by the social darwinist Spencer. Don't confuse it with evolution.
What can we name it now? Can it be called as 'best natural selections'? But, changing name may not change the concept.
