People like to think that evolution is the constant process of becoming 'better' or 'more complex', when it's nothing more than a specific mutation allowing one kind of thing to survive better than another. That is evolution. If a Tiger suddenly became immune to bullets and required next to nothing in terms of food, then it would eventually survive and replace the tigers we have now. The Scottish Wild Cat is becoming extinct, not because of lack of food or predators, but because they are mating with feral 'domesticated' cats. This is making hybrids and thus the proper wild cats, die out.


A single cell exists, it produces ATP by photosynthesis, one day, a single cell ends up mutating and producing more energy by photosynthesis. This obviously reproduces better and thus replaces the original cell, or becomes a new one on it's own. However, one of these cells mutates, this time the mutation is the ability to consume the photosynthesis cells, this allows more time to reproduce as they are the only creature able to use this source of energy. Thus, it survives and is now a new 'species' in itself. One of the photosynthesis producing cells mutates to have a defence mechanism to protect itself... So on so forth. Evolution is nothing more than a random mutation providing that one creature the ability to survive better, be it defence against predators, increased range of ways of getting energy, attracting more mates, so on, so forth.


Humans have stopped evolving in that sense. There are 'super-humans', such as the man who can run naked through -40oc temperatures and be perfectly fine, this, in a sense, is a positive mutation, but having this mutation isn't going to help him have any more children or survive better than a non-mutated human. Humans have access to central heating, large stores of food, clothing and physical attributes are not always looked for by a mate. We have invented currency, something which many believe is more important than looks. Some believe personality and stuff is more important. Mutations that humans are experience, right now, are not going to make anybody more successful. Furthermore, people keep saying "we're evolving flat thumbs cause we text all the time" - They don't understand what evolution is. It is not a beneficial mutation to have flat thumbs and mutations don't happen that quickly.


So, to sum up, he's right. It has stopped, at least it's slown down to such a speed that it might as well of stopped. There has to be mutations akin to X-Men and Heroes (superpowers, essentially) before it'll make a change to humanity, because that way, those superpowers could basically kill everybody else and become the sole 'mate' to those they left alive.

Sir Attenborough is correct, all the Malthusian traps that have kept human overpopulation in check  have been removed by science and social engineering. One Telegraph reader (Veritas) posts a silver lining.

"What a frightening prospect - the underclass surviving to breed us all into mediocrity.  Fortunately the problem is self correcting.  Soon after the real people who produce things to pay taxes to keep these individuals on the benefits they need to stay alive cease to exist the underclass will very rapidly die out and the process can start all over again."

There, that's my politically incorrect post of the week.

Some of the greatest minds of all time have come from the "underclass"...but then again I don't think judging by your comments that you have the intellect to realise that.

  • life good. true fact. when you give a hug, it givez back

Posted 10 September 2013 - 11:27 PM

itz not even possible for any creature to stop evolving. like a few others on this post have stated, i think its true that it has slowed, but also like others have said, there still are plenty of places on earth where survival of the fittest is still a very real thing.

but other than the diseased and dying countries, lets get back on the rich, medicated countries. ill make a few points that proves evolution still is and always will be going forward.

first, diseases. this one kind of speaks for its self, but some people arent aware that world wide plagues can actually happen at any time. and large populations can die out. the argument stating medicine and not evolution will save us is misleading at best. and it leads to my next point. but real quick, people are still continuously being born with immunities to diseases which have no cure. and these mutations gives them an advantage over others to reproduce.

but my next point referring to the medicine thing. society in itself was a form of evolution. because of our unique behaviors and intelligence on this planet, we are therefore capable of evolving in different ways than common animals. the gathering to form societies gave those humans an advantage over the rest and if you notice, most people who do not live in some sort of society have died off millenia ago. second, technology as an evolution. not only does it give advantages to reproduce, but pioneers in these fields are considered great men and therefore are more fit than others. and this technology leads to the medicine, computers, harvesting, communication, etc. the list goes on. but all these advancements give advantages to survive and reproduce. therefore making it a form of evolution.

the last point im gonna make is related to the pioneers comment i made above. the fact is, because of our society, great value is put on men and women who are geniuses, athletes, or otherwise great in their field. whether it be racing or banking. if you are good at something, you are way more attractive than others and therefore are more fit.

all of these examples lead to children who share the traits of their parents AND prove to illustrate that these mutations in ability and advancement will make one, or many, more fit than most. and the cycle continues from there.

final thought: just because we do not mutate a third arm or less teeth or lose our appendix, does in no way, shape or form conclude that evolution has halted in the human population. and in fact, because of science, we know it is literally impossible for mutations and advantages to stop occurring. evolution is merely moving slower because of large population size AND evolution must be looked at from a different point of view due to our intelligence. we have the unique ability to collaborate for the benefit of mankind and regardless if a mutation makes one a better actor, a better athlete, a better banker or a better inventor, the fact is it still provides an advantage to the individual to reproduce and therefore it IS INDEED evolution at work.

I've seen this thesis before.  We don't notice human evolution in that ancients were little if any different from us, but that is only a few thousand years and evolution, while it happens over such time periods, typically takes longer.

That we have changed our environment doesn't mean natural selection doesn't still apply.  So long as some parts of the population produce more progeny than other parts natural selection will continue.

I think he's right. A crocodile  and some species of fish have not changed or evolved in millions of years because they already are the best at what they do. Aside from our bodies being pretty rubbish humans have no need to change. If we need to do something we invent machines to help us.

Darwin would rise from his grave and give this man a knock on his head for even saying humans have stopped evolving.

Great article, but I'm not so sure I agree. He mentioned we have stopped evolution when we started being able to raise 95% of the children we give birth to, but in many parts of the world the mortality rate of under 5s is still really high.
P.
And this: "He also insisted he was grateful to live in the modern day, saying that things were likely to get worse with future generations looking back “at a world that was less crowded, full of natural wonders, and healthier.”.......I am seeing that now, looking at my grandparent's generation.:-) :-)



Every generaton has had somebody say that.

The evolutionary process hasn't been stopped...we've simply been able to change (and only somewhat) away from natural selection by the use of medical and technological advancements. Evolution has not been stopped in the least.

I digree with you and the story.  Humans do not evolve have never evolved.  We change the planet to our needs.  We do not change to fit the environment.  They only difference between you and a native is two weeks. It takes that long to acumate for us to change to the environment.

If the under class dies off so will the other class.  Seeing as the under class does the jobs no one else wants to.  Just like which career is most important in a hospital the doctor or house keeper?
