Evolution of Humans: Developed world and Developing world

Recently a British genetics expert, Steve Jones stated that humans in developed world have stopped evolving, because people there in western countries need not struggle for there survival and the famous theory of Darvin “survival for the fittest” doesn’t come into picture. And he didn’t miss saying that the evolution hasn’t stopped in the developing world, because people there have to struggle for survival.

 

I am no expert in the evolution theory of genetics, nor have I studied biology beyond matriculation, nor I want to challenge the British expert because I am not qualified enough, but I cant suppress something in me which tend to disagree.

 

This seems to be a loose statement and I differ and would like to raise some points

 

He says that humans in developing countries stopped evolving because they need to struggle for survival. Well, I feel this is a very sweeping statement, as not all people in developing countries struggle to survive, many of the people live as lavish life as people in developed countries. So does that mean that in developing countries too some people have stopped evolving? Evolution takes a vast time frame, even for a minor change thousands of years pass. And I don’t think it takes anything more than a century for backward countries to develop, so as per the theory of Mr Steve, nowadays peole of developing countries are subject to evolution and after hundred years they will again stop evolving? It seems Mr Steve has assumed that all backward countries will remain backward in next thousand years.

Or can anyone say it for sure that all people in developed countries need not struggle for survival.

 

Even if I view it from another point of view, and forget about developed and backward countries as mentioned by Mr Steve, can it be assumed that anyone irrespective of country he lives in, if lives in extreme poverty, then his further generations would also live in extreme poverty so that evolution could take place?

I think evolution theory is not same for humans and animals, as animals can not change their life at their will, they will live in jungle, struggle for survival and in the process, will evolve. But in case of humans, as they have got the ability of change their life due to highly developed mind, their process of evolution should be different. Suppose someone lives in extreme poverty and need to struggle for survival, so is his next generation, so next to next generation, but it’s not guaranteed that his 100 generations will live for sure in extreme conditions for evolution to come into picture. In fact it’s very likey that his next generations live in much better conditions.  

 

One more fault (at least I think so) in Mr Steve’s theory is that he has assumed that if conditions so come, people in developed world will not evolve, and also there wont be any crisis which would call for further evolution of humans.

 

Evolution takes place in a very vast time frame, but nature has made it sure that even in a very short time frame further generations of living beings may be born with somewhat better profile, by making two sexes in almost all of living beings.

All the species happen to have a tendency to extend their population and two sexes can help the newborn inheriting better of two. This is a natural refinement process of the living beings, but unfortunately we humans waste it because in our civilization marriage is supposed to happen only between equals.

    hmm I too do not agree with mr steve.

    You put up an intersting point abt refinment of new offsprings :)

    Very well argued :)

    @ Vivek : Extreme poverty in the developed countries is quite different than in developing countries. I have often seen homeless people in Japan and the way they live, eat and stay can be compared with lower middle class here. Some of them sleep in McDonalds and Cyber cafe’s because they do not have a home. Some even sleep in all night adult movie places. My father used to tell me when I was a kid that there will be a day when humans start devolving instead of evolving and we all turn in to just lumps of meat because we stop using our bodies. Food for thought?

    I don’t know how any one can say that the struggle for survival has stopped. Only the nature of the struggle for survival has changed; struggle there is and will remain till men compete for resources, among other things. I don’t see any reduction in competition…it isstill a jungle out there, to use an old cliche.

    Sharad, Thanks for your response

    Odzer, i agree in developed countries, poverty is different than that in India, In fact the poverty line in India, which is about Rs 300/ month, is not even sufficient to fulfill the very basic need of food.

    Vinod, yes i too was surprised by hearing this statement by a genetcs expert

    There may actually be a pertinent fact, that as opposed to evolving, we are really unevolving. Through poor diets and regressive education, people may well be less intelligent, in general and less able to survive within their environment. If one looks at the rise in mental health issues alone, humans seem unable to adapt to the psychological stresses of so called human advancement. We know that in the UK we now have second generation parents who cannot cook. This is a basic skill that has been passed through generations, it could be argued that it was virtually Philogenic to human beings, and is now being lost. This may seem a spurious example, but if one were to think on this point for a while you will find so many more fundamental skills that have been and are being lost to human beings. No matter how far forward we think we are advancing, we are still controlled, fundamentally, by the Earth’s Environment and without the skills and knowledge that has pushed us through the last 150,000 years minimum, we could well be on the way back to nowhere.

    Although bananas has several positive characteristics, a diet of only bananas still seems a bit “fishy”.
    The banana diet broke onto the scene in Japan with such force that many grocery stores the next day literally ran out and could no
    longer provide anyone with the fruit. Most healthy programs you can find online or through your local health stores
    are boring and lack the magic to keep you motivated all throughout, thus you do not end up achieving your goal.

    You can grow gardenias from softwood cuttings in the spring.
    The new Macadamia Natural Oil Nourishing Leave-In Cream also resembles
    the sebum which is one of the many features of this product.
    Don’t let them dry out too much during flowering or they will drop their buds.
