An argument of those that refute Darwin’s Theory of Evolution has been that there is no evidence of evolution continuing to occur in humans or other animals. They demand to know, “what has evolved lately?” Or, “why,” they ask, “can’t we see evolution happening today if it is such a fundamental characteristic of life?”
Over the past 200 years, there has been an increase in the incidence of humans possessing an artery in the forearm that used to wither away in the fetus prior to birth, and it may have ties to evolution in humans. In a report by Flinders University anatomist, Teghan Lucas, it is stated that the prevalence of this median artery “was around 10% in people born in the mid-1880s compared to 30 percent in those born in the late 20th century, so that's a significant increase in a fairly short period of time, when it comes to evolution."
It is predicted that by the year 2100, almost all humans will possess this artery. In the same article, it is noted that, “This rapid rise of the median artery in adults isn't unlike the reappearance of a knee bone called the fabella, which is also three times more common today than it was a century ago.” These anatomical changes are examples of human evolution in action, pure and simple.
Aside from those well-documented indications of ongoing evolution in human anatomy, I also have the impression that more and more people are exhibiting a diminution of intelligence and common sense, with a resulting increase in stupidity and pig-headed, foolish behavior. This, in turn, could represent the onset of a new, evolutionary shrinkage of cortical tissue of the human brain. The latter, however, is merely a personal observation that has yet to undergo scientific scrutiny.
