So life is constantly evolving right? As far as humans, what do you think is our next evolutionary form? Surely it doesnt stop here right? The animals too, what do you think they will look like? Seeing as how we evolved from the cell up into where we are now. This would suggest that we should continue right? How long does the process take anyway, seems like weve been looking this way for quite some time ey?
Side question: Does evolution ever reach a stopping point?
Unfortunately I have some bad news. It does not appear there will be another great evolutionary phase for humans. According to virtually all geneticists humans are degenerating genetically as is everything else.
It's hard pill to swallow but we can observe the effects of genetic degeneration in viruses and bacteria. Illnesses break out suddenly (usually after lying dorment in a natural resorvior.) can be very aggressive and then die out. Like SARS did. As the virus replicates itself mutations or mistakes are made. A mistake here and there doesn't effective it too much but it builds on it. Eventually 10% of it's genetic code has been mutated. It can no longer function and simply dies. That's why so many die during the initial phase of a pandemic but then it sizzles out and people start surviving it. How quickly this happens depends on how high the mutation rate is.
As the aecond law of thermodynamics says everything decays. It appears our genetic code is no exception.
No, you are flat out wrong. The reason people die in the first phases of an epidemic is almost always because the virus mutated in the first place. Then people develop resistance to it, at which point the epidemic phases out unless there is another mutation that sustains it. Flu is a classic case of this going through the cycle of growth to immunity to a mutation allowing for more growth pretty much every single year.
Further you cite Crow as evidence later on. His speculation on human fitness degredation is simply a statement that modern society allows people to survive mutations that would have killed them previously, and so those mutations are accumulating. That is an example of exactly what you would expect to happen when you lower selective pressure, and it applies ONLY to humans (and domestic animals, should we allow it). Your "interpretation" of it is comes from creationist sources who are deliberately misrepresenting it to imply something it does not say, as is your "interpretation" of thermodynamics. It's a hard pill to swallow because it's not a pill at all, its a giant steaming pile of cow dung. You should probably stop swallowing it yourself.
