This book as practically all other books/studies presume that homo sapiens is the supreme criterion by which to judge other species. This is evidently an extreme example of anthropocentrism. Within it’s own pov many more animals are far superior within their own context than homo sapiens.
In the realms of the disinterested natural evolutionary world homo sapiens is in evolutionary terms a dead end branch. It took the species a mere 100.000 years to arrive at the point where it is on the brink of multiple factors leading to extinction.
Unbridled procreation, with a distinct tendency to self-destruction coupled a primal brain which controls an unrivaled capacity for mass destruction is not going to able to compete with even mere jellyfish which outlive us by 500 million years.
Homo sapiens barely overcame in evolutionary time scales, it’s gene pool severely polluted by not only being descendant of the relative few that survived the multiple natural disasters such as the ice ages but nowadays by medicinal progress.
Eugenetics is a dirty word because it was abused by an ideology of the 20th century but anyone with a sound mind can reason that keeping non-viable specimens in that gene pool only serves to pollute it even more.
Homo sapiens has effectively put itself outside of the natural selection mechanism which as a mechanism caused the best specimens to survive and the weakest succumb. By intervening in this mechanism of we barely understand it’s long term implications it would surprise me if homo sapiens as a species would reach a million years let alone the crocodile with a brain the size of a walnut which so far made to 200 million years.
Hubris will be it’s undoing long before
