Micro evolution is demonstrable. Always has been.
Macro evolution doesn’t exist, and has never existed. That is the problem with Chuck Darwin and his adherents.
Darwinism hasn’t quite reached it’s end goal yet, one can only surmise.
Not enough generations for natural selection to create this change. I’ve always thought that brains and genes can create changes on their own to meet various needs. That goes beyond normal natural selection as alterations can occur far sooner. Seen such in very rapid changes in nature, that defy the timeline that pure natural selection could account for. So, in essence, I think there is intelligence involved in evolution.
Reptilian DNA
Wonder how long this “observation” of the median artery has been going on for. How do they know who loses it and who keeps it, never mind who “regenerates” it?
If God wants us to have the median artery to keep going for whatever reason, He does it. There is no “microevolution”, if that word even has a true definition.
Democrats are proof of Devolution.....and that’s NOT “progress”.
ALL LIFE adapts faster than the “world is coming to an end” scare mongers today claim it does.
This is a genetic mutation not ‘evolution’ but labeled as such to get everyone’s dander up.
In the future we will ALL throw a baseball at 150 MPH.
Any natural selection happening here?
That is genetic selection. Not evolution.
No genetic information is being added.
Not evolution. Its not new, just not regressing as commonly as before.
Might be beneficial, and still not evolution; no new genetic material that is favorable that wasn’t there before. Like a human with night vision.
God put it there.
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).
In a pig’s artery.
That was bad.
5.56mm
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.
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.
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.
