An emotional response to evolutionary psychology
This is an attack on what Eldredge calls "ultra-Darwinism" and what he imagines is "selfish gene biology." The main problem in the first instance is that no such animal as "ultra-Darwinism" exists (it's just a slur); and in the second he is tilting against the windmill of a metaphor.
Richard Dawkins, celebrated author of The Selfish Gene (1976), is well aware that genes are not "selfish" in a literal sense. Furthermore, nearly everybody knows that genes work in concert with the environment to shape our biology and our behavior. Indeed, there is nary an evolutionary biologist outside of Bob Jones University who thinks that some kind of endowment, fixed or otherwise, is the exclusive determinate of who we are.
But Eldredge seems unaware of the modern understanding. Not only is he tilting at windmills, he is setting up and trying to knock down straw men that don't exist. Let's look at some of his accusations.
He wants us to know that the drive to eat and stay alive is more fundamental that the drive to reproduce. He calls this the primacy of economics over sex. This is fine, but I know of no evolutionary biologist, anthropologist or sociobiologist who thinks otherwise. They do not mistake the blueprint for the building. Of course in the mass culture a simplistic imbibing of Darwinism and a literal grokking of the metaphor of the selfish gene does exist. It is therefore perhaps a shame that some of this book does not appear in say People magazine to set the general public straight.
Eldredge notes that reproduction is NOT the purpose of life and posits the existential view that if life has a purpose "it is simply to live." (p. 46) But "purpose" is entirely an anthropomorphic notion and has no place in evolutionary biological thinking..
He wants to emphasize the cooperative nature of organisms as opposed to the idea that nature is competitive. He writes that "overt, no-holds-barred competition in the mating arena is, in the last analysis, relatively rare." And then on the very same page (66) he more or less contradicts himself by writing that male birds "stake out a territory (usually constantly defended against intruding males)..." Note that even using such ideas as "defended" ushers us into the land of metaphor. The birds actually react instinctively to the close proximity of other males and try to chase them away. We think they are "defending territory."
Eldredge is saying that the males are not fighting over females or sex but are holding onto valuable real estate--that is, their behavior is economic and not sexual. In a nut shell this is his point: life is lived primarily as an economic venture. What counts is getting enough to eat while avoiding life's many pitfalls. He believes it is a mistake to go further and add that the purpose of these behaviors is to reproduce. Again the bugaboo here is that word "purpose." The truth is that all organisms once they have secured the necessities of life try to reproduce. This is not the same thing as saying that is their "purpose."
What I especially dislike however is not Eldredge's insistence on what should be obvious, but the surly manner in which he attempts to dismiss certain of his colleagues and his attempt to ridicule ideas he either doesn't understand or thinks are being applied too broadly. His dismissive labeling--"hard-core evolutionary genetics," p. 130; E. O. Wilson's "consilience gambit" (why is it a "gambit"?) p. 249, "ultra-Darwinism," etc.--cannot stand for cogent argument. Particularly offensive is his repetition of what he calls "the Pleistocene cop-out." His argument here is that evolutionary psychologists explain current human behavior in terms of what worked on the savannas of Africa during the period of evolutionary adaptation. What he attempts to show is that our behaviors are culturally directed and not dances choreographed by genetic puppeteers. The truth is our behaviors are the product of both cultural and genetic influences working in concert.
Nonetheless our genetic heritage is in no small part the product of our experience during the Pleistocene, and it is part of the genius of evolutionary psychology to recognize this fact. Curiously Eldredge reveals that he understands this because on page 190 he writes (referring to Olduvai Gorge in East Africa), "It is the last best vestige of the environment that produced us, giving us insight into the very conditions in which our bodies--and behaviors--were shaped by evolution." That is pure evo psych, but apparently what Eldredge appreciates on one page is not always evident on another!
This is not to say that this book is without merit. Very well done is Eldredge's answer to the idea that rape is evolutionarily adaptive. (It is not: it is socially abhorrent for one thing; and since we are social animals, the rapist's behavior has met, and will continue to meet, with the severe disapprobation of society to the rapist's reproductive detriment. This is in addition to the fact that infanticide or neglect of the rapist’s offspring is widely practiced.)
Also very much worth reading is Eldredge's exploration of infanticide and his explanation for its near universal practice throughout human history--although his point that it is not adaptive in an evolutionary sense is flawed. Sometimes it is better to have fewer children so that the ones we do have gain our full economic attention. The fact that this was often achieved through infanticide does not alter that general argument.
It is a shame that Eldredge's emotional need to discredit evolutionary psychology mars what could have been a useful exercise. He should have concentrated on arguments against rape as an evolutionary adaptation and eschewed the mistaken and gratuitous attacks on his colleagues. His general concern that those not expert in evolutionary biology sometimes overrate the genetic human endowment and underrate the cultural influence is a good one; but this point has to be made without straw men and ad hominem attacks, otherwise the author loses credibility and begins to sound more like a radio talk show host than a reputable scientist.
Note too that Eldredge's dedication is "In the spirit of Marvin Harris, 1927-2002." Harris was an anthropologist of unusual acumen who liked to debunk popular misconceptions, such as why cows are "worshipped" in India or why Muslims and Jews don't eat pork. He wrote such felicitous and readable prose that his books sold like novels. Well, Eldredge, to paraphrase a politician of recent memory, is no Marvin Harris. But he tries, and when he gets past his rather vague and somewhat mysterious confusion with the language of sociobiology and evolutionary psychology, and goes for the jugular, as it were, of the delusion of adaptive rape, he almost gets there.
