Ron Newby, a former researcher at the Salk Institute in La Jolla, begins his book Tribal: Truth and Consequences by quoting mathematician Jacob Bronowski on the uniqueness of humans among animals.
Newby notes that 98% of the human genome is identical with that of chimpanzees. Members of both species have exhibited acts of violence. Is this the direction of evolution? Newby also notes that the close cousin to chimps, the bonobos, engage in sexual activity and avoid conflict. Despite this Newby posits determinism: “There can be little doubt that interpersonal violence is inherited from our ancient primate ancestors.” (p 14)
The book is uneven though. For example, Newby considers boys liking guns and girls liking dolls to be instinctual behaviors. (p 15) He provides no definition of instinct, but generally an instinct is considered by psychologists to be an unlearned, automatic, and fixed behavior. Thus instinctual hardly applies to liking guns and dolls.
On p 16 Newby writes, “There are likely genetic factors that influence our killer behavior, however there have been no killer gene or genes that have been linked to our proclivity toward killing.” [italics added] By writing with the pronoun “our,” Newby conveys the impression that killing, or the tendency toward killing, is widespread among humans. But this is clearly a marginal behavior. One calculation was that murder was accounted for by 0.0046% of Americans in 2013, and such a percentage may be even lower today.
Moreover, the fact that soldiers having experienced violence or death on the battlefield incur PTSD speaks against a widespread proclivity toward violence; rather it would posit an aversion toward lethal violence.
Following the evolutionary trail and the absence of other hominids, Newby speculates whether Homo sapiens may have killed off the Neanderthals. (p 17) Yet current knowledge indicates that humans and Neanderthals interbred. Academics point out, “Recent genomic research has shown that hybridization between substantially diverged lineages is the rule, not the exception, in human evolution.”
Newby first and foremost states that tribalism offered the advantage of security from outsiders. (p 17) Companionship and pair bonding are mentioned thereafter. (p 18) Hence, a bias appears in Tribal, that of humans being naturally violent.
The book, however, finds its footing in the middle section when it discusses the neurochemical and biological bases for behaviors. Newby then segues into the profoundly important topic of the danger facing humanity from anthropogenic climate change. Everyone should be informed on the topic and what the ramifications for current and future generations might be.
The author pontificates that conspiracy theorists are tribe creators “by offering alternate explanations of events, rather than accepting the reliable and tested theories. Prime examples would include the deniers of the Holocaust — (never happened), deniers of the accepted cause of 9/11 — (It was Israel)…” (p 26) First, who denies that the Nazis rounded up communists, Jews, Roma, homosexuals, etc into concentration camps where many people perished? I am aware of people who question the widespread narrative of the numbers and the method by which prisoners died. I am unaware of people who deny that there were concentration camps and that people died there. Second, I wonder what the author considers to be the “accepted cause of 9/11”? Newby does not state this. Apparently Newby denigrates the over 3,000 architects and engineers who call for a new investigation into the events of 9-11 as conspiracy theorists. In addition, over half of Americans doubt the “official” explanation. Newby fails to grasp that knowledgeable people can posit legitimate theories based on evidence and logic counter to the “official” theory solicited by the George W Bush administration. Such theories may be incorrect, but so might also be the “official” theory. A theory is not a fact. Third, resorting to ad hominem of contrasting views speaks ill of the mud slinger; it is unbecoming; and is not an argument worth contemplation.
Finally, I dislike quotations provided without sourcing as so many turn out to be incorrectly attributed or even conjurations. The only two quotations that I researched turned out both to be dubious. Newby incorrectly attributes the following quotation to Albert Einstein: “Only two things are infinite; the universe and human stupidity, and I’m not sure about the former.”(p 14) On p 59, the author quotes D.H. Lawrence: “Tragedy is like strong acid — it dissolves away all but the very gold of truth.”
Newby intended Tribal as an unhindered read without the clutter of footnotes accessible to the everyday person. That Tribal is, but it consequently lacks depth and oft times left this reader wondering about the factual accuracy and logical coherence of what is being discussed.
