Stop for a minute.
Evolution is a combination of changes, mutations, and the filter, Natural Selection.
Now, what you are talking about seems to be that people that might have died are now living longer then they might have in the past.
Is that correct?

why so fast?
Interestingly, if the scientists who think we're evolving rapidly are correct then that contradicts an oft-stated position of evolutionists here at EvC Forum, that it is small populations that evolve quickly.
This is the issue I hoped to address beginning in Message 19.
Evolution is a history, it's a summary of what is left after all the changes get filtered by Natural Selection. What humans have done is tampered with the filter, we have removed many of the conditions that might have been filtered out in the past.
It seems to me, and I could well be wrong, that when the evolutionists said that small populations evolve quickly, they were talking about the historical viewpoint.
Is it not possible that what we are seing now is not that the change part of evolution has accelerated but that we have enlarged the mesh of the filter so that changes that might not have passed the filter in the past now breeze right through?

Re: Stop for a minute.
If that is the case, what we have done is allow MORE variation into the species human, and so not halted evolution but rather increased the variability in the genetic pool. Far from halting evolution, it would seem we have increased the likelyhood of some part of the human species surviving the next great filtering of Natural Selection.

Re: Stop for a minute.
But surely 'natural selection' then ceases to operate?
Two points. If Natural Selection were to cease operating then the result would be greater variability, not less.
Second, Natural Selection changes constantly. While we might inlarge the mesh to allow more humans through, or even rescue critters that might have gone extinct, we cannot remove Natural Selection. The next time a half mile wide chunk of rock smacks down, there will be selection. Global Warming will bring on selection. The next pandemic will bring on selection.

Re: Speculation
Just like we are now, only more so.
And evolved. LOL
