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.

...or epigenetics. This is supposedly not Lamarckism, but somehow involves the environment in leading evolution down particular paths.

This would be a way to explain the amount of change that is surmised to have occurred over the four billion years of Earth's existence... even though most mathematical models would suggest that even four billion years is not enough time for random chance and natural selection.

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.

“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.
