According to a report, humans still evolve, which is evident in our appearance.
Human Evolution Could Lead To Attractive Generation
Evolutionary biologist Nicholas Longrich claimed that the selection factors of sickness, predators, and interpersonal violence had been substantially reduced. And the capacity to procreate is crucial in a world where genes do not predominate based alone on survival.
Because of this, he thinks that physically appealing qualities, such as being tall and toned, emerge as new features that nature picks for. However, he has also disclosed several other intriguing ways that humanity will change over the next several centuries, such as women becoming pregnant far into their 60s to combat the global fertility issue.
According to Longrich, a scholar at the University of Bath in England who was born in Alaska, we have essentially eliminated predators as a selecting factor and significantly decreased violence as a determining factor.
Although murder and warfare still claim lives, they do so at a lower rate than at any other time in human history. Most diseases are eradicated, but not completely. Coronavirus is neither the same as the flu nor the Black Death. A shark will occasionally devour a human, but most natural causes of death have been eradicated.
He also shared a story from the hunter-gatherer era. Per Longrich, if there were two males and one of them was quite attractive, he made a stupid mistake and killed himself by stabbing himself in the chest or by being eaten by a lion. The remaining guy would attract the woman's attention because, although he may be a little ugly, "ugly still beats dead."
However, attractiveness will become increasingly significant when fewer individuals die, especially when people find their partners online. According to Longrich, people will get taller and more attractive as women choose partners based more on height and men on face symmetry.
"Women often select for height, and I would think we will have reduced levels of baldness - your bald readers may not appreciate this, but baldness may go extinct," the expert said.

Size Plays a Significant Role in Evolution
While Longrich predicted an attractive generation due to women opting for attractive partners, including tall people, another study suggested that the smaller the size, the better in evolution. Short people live longer than their tall counterparts, suggesting that size also affects longevity.
From the standpoint of evolution, little really does appear to be lovely. Little bacteria, single-celled algae, and fungi greatly outnumber the largest dinosaurs, pterosaurs, and mammals, even though they may seem fearsome. In addition, small animals are powerful and old.
The oldest mammals and some of the first dinosaurs (such as the Eoraptor, less than two meters long) were also comparatively small compared to their later, often massive counterparts.
Due to their tiny size, animals may live in a greater range of niches and divide resources more accurately. This enables more species and individuals to survive in the same habitat, a strategy that insects excel at employing.
Over the majority of Earth's history, creatures with a diameter no larger than human hair have controlled the planet.
