Is the human race devolving?

I've just been thinking about the implications of a modern society on humanity and whether or not all the medical and technological aids we have these days, could have serious implications for the long term survival of the human race.

Is it not the case that not having to fight for one's food or mate, nor worry too much about dying from a minor graze, will eliminate prior genetic advances by allowing people with poorer genes to breed and contaminate the gene pool? This is not currently a problem because science has, for the most part, overcome humanity's fundamental needs such as food and water. However, taking the effect of these advances to their extremes, what are the long-term implications?

In terms of Maslow's Hierarchy of Needs, the bottom rung (basic physiological needs, such as survival) barely now even register on the scale of consideration for most people, at least in the developed world. Whereas ten thousand years ago, a human would have woken up wondering htf they were going to survive the day, nowadays the most pressing concern is whether they're going to spend their dollars on a PC or a Mac.

So what's your opinion:

No, we are not devolving. Besides, mankind is getting more and more clever such that evolution isn't important anymore.

Or

Yes, our way of life has serious implications for the quality of the human gene pool. We have already stopped improving as a species and in ten thousand years, everyone will be fat, asthmatic, and allergic to everything. (By improving I mean in physiological terms, not in terms of scientific advances, which are arguably a function of time and resources rather than increasing intelligence).

?

I am not a Nazi or any other kind of supremacist, nor do I propose a cull of weaker human beings. I have asthma myself. I do not have a solution to the problem, assuming there even is one. I'm just interested to hear whether people think that the human gene pool is being sent backwards by the ease with which we can now survive. People that are born with serious physical defects, or are of extremely low intelligence, are no longer any more or less likely to survive than someone with perfect genetics, assuming that the physical defect does not, for example, affect the likelihood of your vital organs working correctly.

Edit: I was hoping to avoid typing this out, but since the word 'pancake' has been mentioned, please add the following to the two options above:

'None of the above - [insert intelligent opinion here]'

Im confused as to why you perceive a heightening intelligence and higher brain functions, resulting in physical condition weakening as the body and physical properties are less important, as an indication we are not evolving? :confused:

Where did I say I thought that? It's a point of view that some may have. If there's evidence that humans are actually getting more intelligent, as opposed to it just being down to improved educational resources, then let's hear it.
 
Somewhere a nitefly is quietly weeping.

Can someone explain what this means? Googling it just turns up another OcUK thread about evolution.

IQ scores improves by 3 points every decade so they have to be renormalised down every ten years.


is say you took the test 40 years ago and scored 80 then you'd have been dim, now you'd be legally retarded.

What edscdk said...where's the evidence that that's down to evolution?

Education and information don't help on properly made IQ tests.


It's supposedly to do with the ever increasing technical problem solving people are faced with in first world countries.

Right so nothing to do with evolution then.
 
People are still going to get wiped out by new diseases, recently cancer.

Cancer has been around for thousands of years and probably long before that also :p.

Nitefly is the biologist on here who always has to come in and correct these "zomg devolution" threads.

usually with a massive post with diagrams.


He usually has to start with why there is no such thing as devolution.

I see.

Just for clarity, I don't think we'll all be crippled blobs unable to withstand a common cold in several thousand years, but I do think that modern lifestyles must have some adverse affect on genetics. Increasing rates of asthma and allergies surely prove this to some degree.
 
Some points:
  1. There is no such thing is devolution

I was interested when I read that, as I was wondering whether biologists presented that statement in line with other scietific 'givens', such as the earth not being flat, or if it was in fact a matter of some debate in the scientific community.

Having Googled and found this article, I see that it's really just about interpretation of the word devolution, i.e. biologists argue that whatever changes occur, whether perceived to be good or bad, are referred to as evolution.

E.g. humans no longer need legs so they have 'devolved', but really they haven't devolved, they've just evolved away from using legs.
