Example of Evolution of Man in the Modern Age

Man is Still 'Evolving'

It has come to my attention that many people are unaware of the recent and ongoing evolutionary changes occurring in homo sapiens sapiens(modern man) in the modern age.

There are endless examples of how humans are still evolving, mentioned in this hub will be three obvious and simple ones. With a current population of 7 billion, living in vastly contrasting environments, different selection pressures (heat, UV exposure, winds, snow, rain etc.) are acting upon us and allowing for adapted populations.

This is all further complicated by new technologies that are preventing certain dangers and in some cases even adding social selection pressures (see myopia/hypermetropia) to mankind's mixing pot.

Just a few facts you should know about:
1. There are complete fossil records of 17 human predecessors, showing gradual development up to our current species: Homo Sapiens Sapiens. There is little doubt that we did not evolve from from these species, there is nothing to suggest that we didn't.

Fossil records are of course evidences of history, and though we think we may know what happened in the past, it is never 100%. Nevertheless, as far as what is most likely to have occurred, humans did indeed evolve from other apes.


2. There are endless examples of human evolution in the modern age.

A few obvious ones include Africans adapting to survive on less food than Europeans, Africans developing predominantly fast twitch muscles (which is why Kenyan's dominate sprinting) and why Africans maintain dark skin in Africa.

A further example is the prevalence of blue eyes in the nordic countries, whereby having blue eyes increases the amount of vitamin D being able to be produces and thus less chance of death from malnutrition.

Another one would be the prevalence of myopia (short sightedness) over hypermetropia (long sightedness), people who couldn't physically read did not survive in the modern age because they would not be able to educate themselves as well (and so were not socially viable to marry and reproduce), whilst those who couldn't see far but could read were able to do so. This explains why 8 out of 10 Singaporeans have short sightedness.


It is also important to note that with the elimination of selection pressures, people who would not have otherwise been able to survive, e.g. people with downs syndrome, paralysis etc. are surviving and are passing on their genes. This is also an example of evolution.

Of course, there is very little chance of evolving a new species of human. Why? Because in order for speciation to occur, reproductive isolation is necessary. A population of animals will only split into two different species if the population is separated for a long enough time for chromosomic changes to occur and spread. Otherwise, the entire population will simply acquire the new genes and evolve together (and therefore not speciate, just evolve).

With the invention of excellent and far reaching transport, there is no large human population that is isolated from the rest of the world, any new gene is able to get out and spread to everyone.

Man from Apes

For those that are afraid of buying into the Ape-Man conundrum, please view this video and marvel in its excellence. Please pay no heed to the title of the video , it is rude, but that has no reflection upon its content!

Do watch it and learn. Most certainly worth the time. Seemingly irrefutable proof!

      There are other evolutional changes going on in modern man that are as close as your ears.

      Just behind your ear is a small hairless depression where your ear, neck, lower jaw and skull meet.

      Also in that depression is a scent gland that is slowly disappearing.

      In time past when we were more animalistic (of course we are nothing more than animals today) we relied on smell to a much higher degree. Virtually every other mammal, as well as countless other species, rely on smell more than any other sense to identify threats and fellows as well.

      But you can easily test the theory. The next time you have been a day or 2 without washing rub your finger in the Depression. The first thing you will notice is that the secretion is far waxier than anything else. Next smell it, your smell is unique and in ancient times would have identified you.

      Mothers always tell us to wash behind our ears. It is normal to think that this is simply because it is a place a child might miss. But in many animals, and very likely in ancient hominoids and early man, infanticide is a common occurrence. A male might very well kill a child that isn't his just as lions or any number of other animals do. It may well be that women may be pre-programmed to try and eliminate the smell that would identify a child as someone else’s to males.

      Very good, informative Hub. I have written a few on the subject myself. Voted up and interesting.
