A really good subject. Thanks for sharing it. Upvoted, resteemed and followed.

Amazing what we have 'learned' over the past century about animal physiology and the potential to alter the course of disease, genetic evolution and eugenics.

It would seem to me, that we are scratching the surface of a hierarchy of knowledge way beyond our capability to perceive.

In light of Man's history of scientific and medical blunders, any list I could produce would simply serve to project an understatement, it seems we play with more than just fire and we modify the future of Man's physiology.

We seem to have little regard for those who are experimented on either. The US government has a prime example in the irradiation of troops and civilians during its first land-based nuclear tests, not to mention the incredible impact on the planet and it's ecology in all nuclear testing.

But that of course, is the least example, dramatic by comparison and well known, but most experimentation and interference involves food additives, genetic modification, preservatives, pesticides, colorants, flavorants, climate changing activities, deforestation, destruction of millions of species daily, disruption of every ecosystem in existence and indoctrination with malicious intent.

While these developments are exciting and most welcome, my mind always warns me that Man is no match for the creativity displayed in the existence of life as we know it and our intervention in the course of 'evolution' has dire consequences in almost every instance.
