Interesting. One of my other random thoughts is that viruses are and have been essential in transferring genetic changes across human populations. This may already be a known thing. I’m a techie, not a geneticist dammit. :)
I have thought that since I was a preteen and refer to it as “evolition” as opposed to “evolution”. I believe the field of epigenetics is coming around to this as well.
What I want to know is why folks in the Old Testament lived for hundreds and hundreds of years and today seems that eighty years is the norm.
Of course this is not an example of evolution. It’s not even an example of natural selection.
It’s an interesting observation that 1) needs to be defined clearly and validated and the 2) the reason for it can be studied.
I would guess if real it has to do with nutrition, similar to our being taller than previous generations (or fatter).
I’ve noticed there seems to be a lot more left handed people than there used to be......................
Simply more variation within species.
Certainly not creating a new one.
That is amazing, and 1870 is not long ago at all when you consider how far back humans date. Makes me wonder if the Egyptians from 5,000 years ago were a foot tall lol lol
In a pig’s artery.
That was bad.
5.56mm
That’s incredible, I think if we could go back in time and see that live we would be utterly shocked how small people were. It really shows how much nutrition and disease can hinder growth
Notice also how the headline is false, i.e. a lie.
The article does not say humans are growing a new artery. It says this artery is lost over time in childhood but now seems to be lasting longer than previously observed.
It’s similar to if baby teeth were lost at a slightly older age.
If the DNA does not account for the ‘extra’ artery, then, it’s not evolution.
If the artery is not inherited by all the generations that follow those individuals who have it, then, it’s not evolution. High intelligence is not necessarily inherited by the generations that follow those intelligent humans.
Ugliness is not necessarily inherited either, and neither is beauty.
The extra artery is used to keep the middle finger erect.
“Not enough generations for natural selection to create this change.”
Yes. These articles are nonsense (not the observations about the artery per se).
And this crap is from SCIENCE publications for the lay readership, ostensibly articles which should be scientifically valid but aren’t.
“This is a genetic mutation not evolution but labeled as such to get everyones dander up.”
What evidence is there this is a genetic mutation?
Sure would. That is micro.
There is a reason Eskimos have an average 500 cholesterol count.
This is not “evolution”. This is “selection”, which sometimes is “natural selection”
The artery exists, and it sometimes doesn’t go away. It used to be that it went away almost all the time, but now for an unknown reason, people are inheriting genes that keep it around.
Could be simple random chance. Could be there is something about the set of genes involved that are also giving some breeding advantage. Or it could simply be that this has been coming for a long time, but we finally got enough people with it that we hit a tipping point.
Remember, EVOLUTION is when something mutates in a way we think is “better”. Selection is when that mutation gains some advantage, so that it is propagated. Most of what people describe as evolution is simple selection.
Micro evolution is demonstrable. Always has been.
Big difference.
It is like the enzyme we now keep to allow us to digest milk as adults. It is not new, it just does not switch off.
The body gets rid of things that are no longer being used. If they are still in use they are kept.
Wouldn't this be more-properly described as an example of devolution?
If you believe in neoteny, that is.
