Monogamy and Medical Sciences Bypassing Advantages of Natural Selection3 min read

In this crazy and progressive world that we have here where monogamy is the established “norm” and medical sciences are advancing at a rapid pace as it has been for many, many decades, we may find that these two things are having humanity bypassing the advantages that natural selection and evolution would provide.

Natural Selection would normally be able to weed out undesirable traits and mutations fairly quickly (speaking in relative evolutionary terms here) by not allowing them to be passed on to future generations. Monogamy and our Advancing Medical Sciences bypasses this evolutionary benefit.


Monogamy ensures that, with birthrates (55% male and 45% female) as they are, just about all males will essentially have a one mate (assuming an even population density) and that each person will have only one choice for a mate, even if that choice is not as good or desirable as they could possibly have or desire.

The top males will have their choice of mates and the less desirable males will have the left-overs. This also means that these less desirable males will all have the opportunity to mate with a less desirable female ensuring that their (collective) less desirable genetics shall be passed on – perpetuating genes that would normally be weeded out due natural selection.

Today’s world with enforced monogamy essentially helps to ensure that “less desirable” mates will be able to find a mate and will be able to pass on their less desirable genes to future generations. This ensures that genetic mutations and abnormalities will be carried on to future generations and it will take much longer for them to be removed from humanity’s gene pool; whereas in cases where natural selection is allowed to run rampant the mates with less desirable traits or abnormalities would have their genes not passed on due to not being able to find a mate, thereby removing defective genes from the gene pool earlier, which allows for a higher quality and healthier humanity sooner than later.

Medical Sciences

Advanced medical sciences help to ensure that people with defective genes live longer and are more able to find mates; and therefore live longer and be more able to find a mate allowing them to carry on their defective genes to future generations, again, bypassing the advantages of Natural Selection.

People that would normally die off due to a severe genetic disease or would be shunned due to physical deformity or weakness are able to find a cure for their health and physical condition or are able to have the indications or effects of a physical abnormality removed or minimized, and therefore are able to procreate due a longer life span or abnormality minimization.


Advanced medical sciences allow people to live longer and healthier, and are able to hide evidence or minimize the effects of genetic abnormalities. Combined with monogamy’s gift of a higher probability of finding a mate make it much more likely that defective genes will remain in humanity’s gene pool longer instead of being weeded out due to no being able to find a mate.

  1. So, would I be considered one of the inferior humans? I have ESRD, and have been deformed over the years by medical experimentation. I’m weaker than everyone else because of the build up of urea in my body, as well as muscle atrophy from Guillian Barre Syndrome. I feel as though I am completely unlovable in this society, and have never known unconditional love. Am I being weeded out by God Himself? Am I unlovable? Am I inferior?

  2. Everyone has physical and emotional problems. There are no exceptions to that. I have problems. My wife has problems. Everyone I know has some sort of problem. Some people have more problems than others.

    From a cold and purely academic standpoint, obvious genetic or physical limitations are generally avoided when one is trying to find a mate. One is always looking for mate that can grant a genetic or resource advantage to ones children that we ourselves do not have… generally a step up or at least not a step down.

    Evolutionary psychology gives much credence to the phrase ‘birds of feather flock together‘.

    This discussion does not take into account love or emotions at all. This is all said purely from the stand point of a hard science.

    I know it is hard for you. Our instincts are cold and uncaring especially in such civilized days as these when such instincts are not so necessary. Our instincts are wrought of survival and perpetuation and nothing else.

    Many people spend their lives trying to control or harness their survival/animal instincts… to rise above them… to be more humane in our relationships and consideration, but that is battle that is not often won.

  3. Ah…but sometimes traits that were once an advantage can become a disadvantage, take for instance diabetes. In the ice age, it helped people from freezing to death. Now it leads to all sorts of illnesses.

    My personal take on it is that one’s actions affect there genes. If one does what they can to live a healthly lifestyle this will affect their genes. Also, I think some of the birth defects could be avoided by a health lifestyle. For example, pregant mothers drinking for one example.
