Dinosaurs Show that Size Does Not Assure Success, or Even Survival

(p. 504) If the Museum of Natural History was going to be, as Carnegie intended, a world-class institution, it needed more than mummies, ana-(p. 505)tomical models, and Appalachian minerals. It had to have a dinosaur or two. The dinosaur was more than simply a crowd-pleaser. For Carnegie and other devotees of evolutionary science, it was an apt symbol of the unpredictability of a universe in which species and races fell into extinction when they failed to adapt to new environments. For men of slight stature, such as Carnegie, there must have been something quite enthralling about this most vivid demonstration that size and power did not guarantee survival.

(p. 40) Warren, a science journalism professor at North Carolina State University, never dreamed of becoming a cadaver dog handler, searching woods and rubble for dead bodies. She just wanted a new German shepherd puppy after the death of her saintly dog Zev. What she got was Solo: “a maniacal clown,” loving and intensely smart, but “an unpredictable sociopath with other dogs.” . . .

. . . Fortunately, Warren understood behavior issues are rarely the dog’s fault. They often just mean humans haven’t found the right way to channel their pet’s energy.
. . . it’s . . . a moving story of how one woman transformed her troubled dog into a loving companion and an asset to society, all while stumbling on the beauty of life in their searches for death.

M.R.I. Evidence that Emotions Are Similar in Dogs and Humans

(p. 40) Gregory Berns wasn’t sure if his pug Newton really loved him. Newton wagged his tail and gave kisses, but that wasn’t enough. Berns, a neuroscientist, wanted hard data. He also hoped to uncover “what makes for a strong dog-human bond” and how that might improve canine welfare. So he built a special M.R.I. machine, and trained dogs to lie still inside it, allowing him to study their brains. Though the results may seem obvious to dog lovers (that humans and dogs experience emotions similarly), they’re not a given for science. Berns’s book is a beautiful story about dogs, love and neurology that shows how nonhuman relationships are inspiring researchers to look at animals in new ways, for their benefit and ours.

Evidence Babies Are Born with a Sense of Fairness

JustBabiesBK2014-01-18.jpg

Source of book image: http://news.yale.edu/sites/default/files/imce/main-bloom.jpg

(p. 15) Is morality innate? In his new book, “Just Babies,” the psychologist Paul Bloom draws from his research at the Yale Infant Cognition Center to argue that “certain moral foundations are not acquired through learning. . . . They are instead the products of biological evolution.” Infants may be notoriously difficult to study (rats and pigeons “can at least run mazes or peck at levers”), but according to Bloom, they are, in fact, “moral creatures.”

He describes a study in which 1-year-olds watched a puppet show where a ball is passed to a “nice” puppet (who passes it back) or to a “naughty” puppet (who steals it). Invited to reward or punish the puppets, children took treats away from the “naughty” one. These 1-year-olds seem to be making moral judgments, but is this an inborn ability? They have certainly had opportunities in the last 12 months to learn good from bad. However, Bloom has found that infants as young as 3 months old reach for and prefer looking at a “helper” rather than a “hinderer,” which he interprets as evidence of moral sense, that babies are “drawn to the nice guy and repelled by the mean guy.” He may be right, but he hasn’t proved innateness.
Proving innateness requires much harder evidence — that the behavior has existed from Day 1, say, or that it has a clear genetic basis. Bloom presents no such evidence. His approach to establishing innateness is to argue from universalism: If a behavior occurs across cultures, then surely it can’t be the result of culture.

Philosopher Herbert Spencer Defended Capitalism in America

BanquetAtDelmonicosBK2013-08-12.jpg

Source of book image: online version of the WSJ review quoted and cited below.

Spencer was sometimes a much better philosopher than the modern caricature portrays, a caricature exemplified by the review quoted below and, perhaps, by the book reviewed. I would like to look at this book sometime, because there may be some interesting history in it—though I am not optimistic about the book’s economic assumptions, or its account of Spencer’s philosophy.

(p. A11) Herbert Spencer, the 19th-century British philosopher, is remembered today as the forbidding — almost forbidden — father of “Social Darwinism,” a school of thought declaring that the fittest prosper in a free marketplace and the human race is gradually improved because only the strong survive. In Barry Werth’s satisfying “Banquet at Delmonico’s,” Spencer is also a querulous 62-year-old celibate whose 1882 American tour culminates in a feast to which are invited the “mostly Republican men of science, religion, business, and government” who shared and spread the Spencerian creed.

Applying Darwinian insights about evolution to political, economic and social life — though he did not himself use the term “Social Darwinism” — Spencer concluded that vigorous competition and unfettered capitalism conduced to the betterment of society. He predicted that the American, raised in liberty, would evolve into “a finer type of man than has hitherto existed,” dazzling the world with “the highest form of government” and “a civilization grander than any the world has known.”
. . .
The public clamor over the visit of a dyspeptic foreign philosopher to these shores was partly due to the indefatigable promotion of Edward Livingston Youmans, Spencer’s chief American proselytizer, who called his beau ideal the most original thinker in the history of mankind. Youmans is among the several critics and apostles of Spencer and Darwin whose profiles Mr. Werth skillfully interweaves in this Gilded Age tapestry.

A Path to Bringing Back the Extinct Woolly Mammoth

(p. D3) For the first time in 43,000 years, a woolly mammoth has breathed again on earth.
Well, not the mammoth itself but its hemoglobin, the stuff in red blood cells that takes on oxygen in the lungs and offloads it in the tissues. By reconstructing the mammoth’s hemoglobin, a team led by Kevin L. Campbell of the University of Manitoba in Canada has discovered how the once-tropical species adapted to living in arctic temperatures.
Dr. Campbell’s work raises a somewhat astonishing possibility: that much of the physiology of extinct animals may one day be recoverable from the DNA extracted from their remains.
. . .
Two years ago, scientists at Penn State University sequenced a large part of the mammoth’s genome from a clump of hair. They published the sequence along with the arresting suggestion that for just $10 million it might be possible to complete the sequence and use it to generate a living mammoth.
The suggestion was not as wild as it might seem, given that the idea came from George Church, a leading genome technologist at the Harvard Medical School. The mammoth’s genome differs at about 400,000 sites from that of the African elephant. Dr. Church has been developing a method for altering 50,000 sites at a time, though he is not at present applying it to mammoths. In converting four sites on the elephant genome to the mammoth version, Dr. Campbell has resurrected at least one tiny part of the mammoth.

Chagnon Enraged Cultural Anthropologists By Showing Tribal Violence

NobleSavagesBK2013-04-05.jpg

(p. C) In the 1960s, cultural anthropologists led by Marvin Harris argued that conflict among prestate people was mostly over access to scarce protein. Dr. Chagnon disputed this, arguing that Yanomamo Indians’ chief motive for raiding and fighting–which they did a great deal–seemed to be to abduct, recover or avenge the abduction of women. He even claimed that Indian men who had killed people (“unokais”) had more wives and more children than men who had not killed, thus gaining a Darwinian advantage.

Such claims could not have been more calculated to enrage the presiding high priests of cultural anthropology, slaughtering as it did at least three sacred cows of the discipline: that uncontacted tribal people were peaceful, that Darwinism had nothing to say about human behavior and culture, and that material resources were the cause of conflict.
. . .
Meanwhile the science has been going Dr. Chagnon’s way. Recent studies have confirmed that mortality from violence is very common in small-scale societies today and in the past. Almost one-third of such people die in raids and fights, and the death rate is twice as high among men as among women. This is a far higher death rate than experienced even in countries worst hit by World War II. Thomas Hobbes’s “war of each against all” looks more accurate for humanity in a state of nature than Jean-Jacques Rousseau’s “noble savage,” though anthropologists today prefer to see a continuum between these extremes.

Darwin’s Worry About Gradual Evolution of Eye

Darwin and others have worried about whether an eye could have evolved gradually. The issue is whether the earlier gradations leading up to the eye would have given any survival advantage. Matt Ridley’s column, quoted below, argues that Darwin need not have worried.

(p. C4) Davide Pisani and colleagues from the National University of Ireland have traced the ancestry of the three kinds of “opsin” protein that animals use, in combination with a pigment, to detect light.
. . .
. . . , the anatomy of eyes shows every gradation between simple light-sensitive spots and full cameras. The detailed genetic evidence of descent with modification from a single common ancestor further vindicates Darwin and has largely silenced the Intelligent Design movement’s use of the eye as a favored redoubt.
After the duplications that led to working opsin molecules, there seems to have been a long pause before complex eyes appeared.
The first lensed eyes that fossilized belonged to the trilobites which dominated the Cambrian oceans after 525 million years ago.

Darwin Shared His Thought Processes Without Condescension

“SAGE OF AGES; Portrait of Charles Darwin in 1881, by Julia Margaret Cameron.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. C14) . . . Mr. Johnson observes:

No scientific innovator has ever taken more trouble to smooth the way for lay readers without descending into vulgarity. What is almost miraculous about the book is Darwin’s generosity in sharing his thought processes, his lack of condescension. There is no talking down, but no hauteur, either. It is a gentlemanly book.

In both style and substance, this passage is classic Paul Johnson.
. . .
What makes Darwin good, in the biographer’s estimation, is the scientist’s democratic dissemination of knowledge. Darwin triumphed with “The Origin of Species,” Mr. Johnson contends, not only because of his ability to portray the theory of evolution as the inescapable outcome of his decades of study and the work of fellow scientists, whom he was careful to praise, but because he was acutely aware that he had to present his notions of natural selection and survival of the fittest so as not to stir up public controversy. To an extraordinary degree, Darwin deflected attacks by couching his discoveries in terms of the plants he liked to examine and cultivate. He had relatively little to say about human evolution.

Harvard University Press Dropped Watson’s “The Double Helix” as Too Controversial

Crick did not like Dr. Watson’s book at first.” Source of caption: print version of the NYT article quoted and cited below. Source of photo: online version of the NYT article quoted and cited below.

(p. D2) Anyone seeking to understand modern biology and genomics could do much worse than start with the discovery of the structure of DNA, on which almost everything else is based. The classic account of the discovery, “The Double Helix,” by James D. Watson, was first published in 1968 and has now been reissued in an annotated and illustrated edition.
. . .
An appendix makes it clear how close “The Double Helix” came to being suppressed. Dr. Watson sent the manuscript to many of the central players, inviting their comments on its accuracy. Harvard University Press had accepted it for publication, but the Harvard authorities came to feel it was too hot a potato and dropped it.
Atheneum Publishers, which picked it up, requested a blander title — previous versions had included “Honest Jim” and “Base Pairs.” The latter — referring to the paired sets of chemical bases that form the steps in the double helix, and by extension to the two discoverers — gave particular offense to Crick, who failed to see why he should be considered base. Atheneum’s lawyers then tried to make the text inoffensive to the many possible litigants.
But Dr. Watson was able to resist many changes. He had cannily persuaded Bragg to write a foreword, and this endorsement from an establishment figure provided sufficient protection for the book to be published. It proceeded to sell more than a million copies.
