To some of you science head out there that care to shine your opinion on this topic, which I have been wondering on and off for quite some time now.

Has evolution for human being come to a complete halt?

My answer is yes. We have seen that human was constantly changing and evolving throughout time......until modern civilization came to be. What I meant by that is the advancement of modern medical practice/techiques. Any mutation that occured these days are being fixed by modern doctors. How do you know the person borned with 6 toes will not be the fittest species? How do you know that a person that is borned with anything abnormal will not turned out to be the fittest species? Since we fixed the issue to begin with, we will never find out. Hence, I came to the conclusion that human being may have come to a big wall when it comes to evolution.

here, this is funny but true

Homo Sapiens appeared around 200,000 years ago. Anatomically similar humans to modern day people appear around 130,000 years ago. All humans lived in smaller nomadic groups as hunter-gatherers until around 10,000 years ago. The ability of medicine to correct anomalies has arisen within the past 100 years, although unnatural selection has certainly been around a lot longer. Regardless, our current state is merely a blip in the timeline of human development, and a speck on the evolutionary chain, making it impossible to predict where the species will go from here.

With that said, we are experiencing evolution at speeds far greater than any species has in the past.. it's called cultural evolution, and it's probably a larger decider of our future than any natural physical changes that may arise.

 

^^ agreed. also our modes of thought and rationality are growing. not to mention our athletes are still getting better and evolving.

if i didn't wear glasses i would have died off long ago.

bleh.

 

science is making us lazy slobs and throwing darwing out the window.

we will evolve into a puddle of mud because we invent things to make up for natures mistake. survival of the fittest no longer exist for humans because of affirmative action.

 

I disagree.

The human body exists in a world vastly different from the "thousands" of years ago. And hence will continue to adapt and evolve.

Survival of the fittest will always be a factor with the human race. Medical science is helping out those that evolution should have cleaned up long ago. Nature will adapt.


My opinion anway.

 

I'm looking at this as a 2 phase evolution. Natural evolution and artificial evolution. Basically, I believed that natural selection/evolution had ceased when the era came when human was smart enough and started to assisted human development through uses of advance techniques, which I called artificial selection/evolution. At this phase, it is us that shape the form of human instead of nature. Nature have to throw something at us that would change the face of the earth if the natural evolution was to start again. (Like the Ice Age)

There are articles that talked about genetic mutations that help certain groups to be immune to certain plague. But as far as physical appearance, it's the way I had described.

 

That tends to suggest an immediate reaction to a specific event.


Both would be somewhat progressive...

 

Excellent point. Medicine has allowed many to survive that should have died. Now we have "super diseases" that are overcoming medications that worked for decades and people's immune systems are becoming weaker and weaker. In the battle of armor and weapons, the weapons always win in the end.
