This is pretty interesting to hear the word selective breeding, Humans have bred selectively for a very long time and this is true to a worldwide human population. In Europe too there were arrange marriage in the past and this kind of Arranged marriage system and Caste system is much more prevalent in Asia. In the past the warlord Bred with the warlord womens so as to have better warrior babies. And the examples are numerous how they bred. Hence there are four human traits which is seen as key human traits that people bred in past.
Intelligent Type
Strength Driven
Business and Diplomatic
Followers/ Hard Workers.
The traits which were very important in early humans like strength has been a lot less important hence I have listed Intellect as the first primary driving factor for human evolution in future.
Why do we use Selective breeding/ Arrange Marriage System in Humans?
We have been breeding animals and plants to gain certain traits and their behavior. May be our ancestor figured out this things in animals and plants and started to use this approach in their society so as to have better babies.
There are certain Advantages and disadvantages of Selective breeding.
1. Inhibits Evolution The frequency that certain alleles are introduced into a species is drastically cut down with selective breeding. This could cause a severe lack of evolution in species where it would naturally occur.
2. Harmful Pathogens While certain pathogens that cause disease and illness may be eradicated, it could provide ideal situation for new and more harmful ones to develop. These new pathogens would then continue to be passed down during the breeding process. I have seen many group of population having certain kind of ancestral disease in human population.
3. In Breeding Risks One great example of inbreeding that has resulted in devastating effects is the white tiger. They have been in bred so long, in order to obtain the striking white color, that severe mutations have begun to occur. These same risks apply to any livestock or plants that are being inbred in order to achieve supreme traits. Similarly in humans we haven’t seen such mutations but in muslim population where a heavy inbreeding occurs there needs some research. Regarding the consequences in human population. China might be also one big example lacking diversity in their population.
4. Diversity Is Lost Diversity is another thing that is negatively affected by the use of selective breeding. Since the purpose is to breed in or out traits, you can lose some all together. Whether you are talking about humans, animals, or plants, diversity is a necessity for the longevity of the species. English bulldogs might be considered a cool looking dog, but have breathing difficulties and such small pelvises that they often have to give birth by causation.
Due to lack of diversity the problematic genes appears in the human babies again again and the children carry the disease to future.
5. Things Naturally Evolve Natural evolution occurs in nature over time. This is so that the species can adapt to a changing environment. When you use selective breeding, you take away the ability for a natural process to cause the animals to evolve. This could easily cause important evolution to not occur.
Hence we have so many disease right now with the biggest population boom we see this effect in the most amplified way humans can ever see.
Conclusion: Hence when nature works in its own it has its own beauty and is precise in many more ways that human can’t think till now. Gene edited babies are also another extreme which we don’t really know about. This might be our next solution but we need more research in this field. Experimental babies brought to life via gene editing like in china could bring problems hence this field has to be better analyzed before using such techniques in human beings. The Most important thing is we won’t learn if we are afraid to make mistake, Simulation and AI could omit this hit and trial process in future.
