Is human evolution over?

Geneticist Professors have said that
human evolution may be over, and that we may now,
as a species, be on the slippery slope to extinction.
we would have quickly starved to death
in our hunter-gatherer days , unable to keep up with
prey animals or to see well enough to tell "nutritious"
from "poisonous".
What this means is that we have a rate of survival
to age 21 that is almost 100%, double what it was in
ancient times. its beacuse of new technology and medicines which result - we are isolated from natural
evolutionary pressures, so there is nothing to
stimulate natural selection, nothing to w**d out
potentially-dangerous mutations. We are
stagnating.


Some have argued that we are destined to evolve
into super-beings, others that we are turning into
dim-witted goblins incapable of anything more
demanding than watching TV.
bt is it true???
SO WHAT'S NEXT ???

A very interesting question.
The quick and easy answer to the question is that it's not. Random mutations are still occuring in the human genome and some of them are being propagated with a higher frequency than others.
But to get to a more central point of the question, does the pressure of natural selection fall on humans anymore? I would argue that the pressure is only there in extreme cases, that the only traits being weeded out are the severely negative or lethal ones. Our decision making process for mate selection is much, much more complex than any other animal's, and it doesn't revolve as much around genetic traits as it does around many other socioeconomic factors. Sure, there are some genetic factors, lean people are in general considered to be more attractive then fat people. But do those lean people actually reproduce more? Statistics say no, that we are actually getting fatter. This might have more to do with lifestyles then genetics, but it's still food for thought. Between our ability to travel great distances and create a huge and diverse gene pool and our efforts to stamp out natural selection, I would have to say that while we are still evolving, we are evolving in a more random and slower fashion.

Of course, "society" has only been really influential for a few millenia, which is, evolutionarily speaking, a blink of an eye, so most of this debate isn't very significant at this point.


This answers is copied and pasted. I am being honest enough here.

In my opinion,the answer to this question is deffinitely no.Why should human evolution stop now?We are making scientifical progress at a rate that has never been considered possible.Our children have iq's so high due to all means of communication nowadays.Human evolution means more than standing on two feet.We are evolving as a society thus all those who fail to meet the expectations have a hard time in jeopardizing evolution of the rest.Maybe we wont be able to fly in the future using something given by evolution,but we have reached the moon.That is due to evolution.Its what differentiates us from animals,in this matter at least.When animals start using tools they are considered intelligent.That is why the answer to this question must be no,because evolution of the human race can not be associated with evolution of the human body.

We as a human will never stop evolving, as new studies have shown that time and again.
It's been also studied that slowly over generations we are becoming less potent and maybe some day humans will become sterile due to evolution.
As we adapt to our new surroundings, we are becoming more fragile and dependant upon gadgets etc, so much that its affecting every thing.
Our lifestyle has created a lot of problems and diseases.
This is all due to evolution

No it hasn't. There are societal forces that have taken over for many of the natural ones.
Natural selection does not equal evolution although it will always play a part. There are other major mechanisms such as genetic drift, gene flow etc.....

ya i agree .
evolution still exist

it will continue ...no one can know as it happens in much slower way .. may you born millions of year later and watch the change .
