Declining testosterone key to human progress

About 60,000 years ago in Africa there was “great leap forward” as coined by Jared Diamond for human kind when there was surge in its development with making better tools, painting on cave walls, emergence of kitchens, disposal of waste and eating cooked food. This bunching of development in several spheres was hitherto attributed to a mutation of the human gene, higher intake of calories, etc.

Recent research from Duke University shows that the shape of the human skull changed over time. This had a high correlation fall in levels of testosterone in humans. As testosterone levels declined facial structures became less severe with softer features. These biological changes with reduced testosterone levels led to reduced aggression and more peaceful and cooperative human natures resulting in greater strides in art, culture and technology.

The essentially resulted in more adaptive homo sapiens which ensured the survival of the species. This is similar to trees which are able to bend are able to weather harsh storms. There could be similar developments in other mammals, birds and fish during the course of their evolution with the more severe variant giving way to more gentler descendants.

During the past two decades it has been observed that in the more advanced and educated societies there has been a pronounced decline in male fertility. Some of the past researches have given the root causes as tighter pants, hot water baths, mounting stress of our hypercompetitive era, longer working hours both at office and home thanks to being digitally online 24/7, decline in libido with both spouses having different working hours where they meet probably once a week, changes in diet with preponderance of palette pleasing processed food, secular fall in sperm count….

Trends in the future:

1.    Lower desire to procreate among advanced societies.

2.    Increase in adoptions from poorer countries and societies.

3.    Increase in surrogate mothers.

4.    Increase in no of single individuals both men and women.

5.    Increase in divorces.

6.    Asocial living.

7.    Widening in the range of sexual preferences and gender categories in humans.

8.    Humans living with robots with whom they can have sex.

9.    Group and polyamorous living and families.

10.Men using more cosmetics and beauty care aids with the market for such fashion products rising exponentially.

11.Move towards unisex clothing and fashion gear.

12.Reproduction in females without males.

13.Reproduction in females with help of sperm banks.

14.Test tube births.

15.Males becoming more asexual with further lowering of testosterone.

16.Declining population in advanced societies increasing populations in non-advanced societies.

17.Lower intelligence levels in macho males and intelligent males lower on macho scale.

18.Move towards geriatric societies.

19.Rising intelligence levels with exponential creativity and digital lives.

20.Age of Singularity where computers and humans meld.

21.Independent of testosterone levels, the most profound change in the future is likely to be on the climate change front where entire or most of humanity could be at risk.

All the giant strides now and in the future shockean times to come in technology, science, arts, culture.. have perhaps reached their tipping point where further development is probably counterproductive for humanity as they are dehumanizing society and pushing the environment close to the edge.
