The recent study out of the University of Sheffield has found that the humans are still subject to the Darwinian selection, in spite of modern wonders of the technology and medicine. Of course, an idea that the human is still progressing is one that no one ever questions lawfully. Evolutionary change is the mathematical necessity as so long as at least one of following influences will occur to the genetic population. Those influences are non-random mating, mutation, genetic drift, genetic flow or natural selection. This is the evolutionary principle also called as Hardy-Weinberg equilibrium. In this article, we will be knowing about the changes occurring in humans after 100 Decades from now.
Here are some of the changes that will occur in humans after 100 Decades:
Humans of Future may shortage wisdom teeth:
Many people think of the wisdom teeth as the pesky medical annoyance. Also, they think that they must surgically remove them before they begin to erupt. The major reason for removal is because most of the modern human’s jaws are too small to contain them without disrupting other teeth. Common postulation is that the vestigial molars are originally evolved in the ancestral humans. During those times, the human jaws were bigger and the diets included hardier plant material.
So, it’s not surprising that the wisdom teeth are starting to disappear. In fact, thirty-five percent of the people are already born without the wisdom teeth. Many people are born with the just one or two of their wisdom teeth. When the traits are no long necessary, the evolution tends to favor an elimination of that trait to save the unnecessary energy expenditure. Thus the human after 100 Decades may lack the wisdom teeth entirely.
Race Contrast may vanish:
One of the main driving forces of the expansion is the gene flow. This will occur whenever there is open mixing of the genetic material between the populations. The main fact is that the humans aided the world by the modern transportation means. As a result, there is very few human population that remains isolated. One result of the gene flow is that the genetic differences between the populations tend to vanish. On other words, the racial differences are likely to blend together. The humans of future may look at the lot more alike.
Humans of future may effectively resist to Heart Disease and Diabetes:
Diabetes and the heart disease is some of the main cause of the death in the developed world. This is because the modern diets are high in fats, empty calories and cheap. Therefore, there is currently the sufficient selective pressure on the place. Hence, the humans of future can better adapt to these diets and such diseases become ineffective. The dietary adaptation is not uncommon even in the recent human expansion.
Humans of Future Have Less Hair:
The humans are usually referred to as a hairless ape. This is the facetious title; like all the mammals, humans do have the hair. Clothing, along with the modern technology such as heating and air conditioning, has made insulating properties of the body hair démodé. Although an evolutionary fate of the body hair can be specifically difficult to the project. This is because it also acts as the signifier for the sexual selection.
Humans of future may be more susceptible and physically weaker to pathogens:
As already noted, that the expansion tends to favor the elimination of the no longer needed traits. The human is no longer requiring the robust muscles to perform the feats of the strength. In future, the people may have a weakened immune system and be more susceptible to the pathogens. Therefore, the humans of future may become dependent on the medical technology.
So, the above-discussed changes are likely to be observed in the future humans. How many more years would the humans exist on earth? How would be their impact on other living beings? What lasting impression will they make on earth after 100 decades? Even we doubt if the life will exist till next 100 decades or not? But the studies indicates that if it will exist, then the above biological changes may naturally occur in the future humans.
