if we continue to pollute the earth will we ever develpe lungs to detoxify these polutitants need refences?

Answer 1

From an evolutionary point of view, YES WE WOULD, but it would take a very long time of selective reproduction and survival of the fittest.
Those of us who don't die out due to the polution will only live to reproduce over and over until our future offspring develop better lung systems to contend with the higher levels of CO2, flourocarbons and other types of poluttion.

The poster before me suggests that their is no evidence to suggest that some types of humans have better lungs than others. This is not true. I have seen studies for example that suggest there are differences for cancer risks among humans based on race.

If this is possible, I see it as possible that speciation might play a part in changing our anatomy to adaptation.

The only problem I see is that Evolution is a theory and can't be reproduced in a lab. Though there is plenty of evidence just looking in the animal kingdom that evolution adapts to changes in the environment, no one is certain how well this will work for humans.

Keep in mind though that humans have the advantage of technology. If it came down to it, we could develop air tight domes using non-degradeable plastics or glass like those in the biospheres.

Answer 2

nope, because it's not a simple matter of the have and the have-nots, there is really no one that has lungs that are better suited to tolerating the pollutants, it's just a difference of time before a person is infected. The lungs are just not an organ that can easily adapt to such things so quickly.

Answer 3

From an evolution stance, not likely. Lung diseases (other than CF and asthma) don't tend to kill people until after they have already spread their genes (after they've had kids). Therefore lung strength and disease protection it is not a factor that would be selected for or against.

Even though Asthma can present in childhood, it is generally treatable and would not prevent the carrier of it from passing on genes that make future generations suceptible (it won't keep people from having kids).
