What's In A Name? An Individualist.

People with uncommon names are likely to be individualists, according to a study of Scandinavian names and behavior reported in The Economist 
(February 16, 2019). Those who left for America to pursue their own personal success when frosts ruined harvests in the 1860s were unlike those who stayed behind to marry and to spur the growth of labor unions at home. On the other hand, a study at Boston University found the U.S. western frontier was populated with immigrants who had rare names, learned English, and married outside their own nationalities.

     These findings reflect those Robert Plomin details in his new book, Blueprint: How DNA Makes Us Who We Are. (Also see the earlier post, "The 'Where Did I Come From?' Game.") Plomin's studies of twins reared together by the same parents and those raised separately by adopted parents blur the formerly accepted notion about the separate influences of what is inherited in an individual's nature and what the nurturing environment affects.

      Inherited physical characteristics, such as height, influence who people in the environment look up to as their leaders. Likewise, behavior traits a person inherits influence the same environmental reactions both natural and adopted parents have toward different individual children. Parents will read to children who inherit a desire to be read to, while a child who breaks the rules and marches to his or her own drummer may badger a parent to buy a musical instrument and take lessons in jazz.

     It seems those who bear unusual names: 1) inherited an individualistic temperament from the parents who named them, and 2) their individualistic behavior probably influenced parents and others in the environment to respond to them in positive and negative ways.

     Where individualistic behavior is valued, an unusual name could serve as a leading indicator of the right person for the job. The art world that welcomes innovation welcomed Salvador Dali the same way entertainment does Dolly Parton and Oprah; military strategy, Dwight Eisenhower and Ulysses S. Grant; human rights, Cady Stanton and Sojourner Truth; vehicle innovation, Elon Musk.

     Ambitious politicians, such as Kamala Harris, Marco Rubio, Alexandria Ocasio-Cortez, Beto O'Rourke, and Cory Booker are looking at a mixed pro-con history of the environment's reactions to candidates with unusual names. Zachary Taylor and Barack Obama were successful; Horace Greeley and Adlai Stevenson were not.

The "Where Did I Come From?" Game

Not only do genes influence the color of our eyes and other physical characteristics, but findings, reported in Blueprint: How DNA Makes Us Who We Are by Robert Plomin, indicate genes also have an impact on our behavior.

    In other words, besides influencing a person's height, genetics also can have more to do with a person's plans to attend college than a household environment filled with books. Genetic tests that purport to measure innate abilities, however, do not predict if a person will find, make, or choose a way to activate an innate trait by, for example, actually attending and graduating from college.

     The realization that genetics have an impact on both body and behavior raises even greater concern about using the CRISPR-Cas9 technique to edit human genes, something that it appears Chinese researcher, He Jiankui, already has done. In contrast, what the Seleggt egg-producing company in Germany is doing, according to trendwatching.com, is very worthwhile. Seleggt is identifying the sex of male check eggs before they hatch, using the eggs for fertilizer, and eliminating previous inhumane methods of killing about 4.6 billion male chickens every year.
                                                                                                                                Editing affects not just one person's DNA; changes are passed on from generation to generation.That is all well and good, if, for example, an entire family tree inherits immunity to an infection. But mutation of a chosen gene, however well intended to be beneficial, might also cause mutation in non-targeted genes and other undesirable changes, such as deletion of sections of DNA, in the mix of chromosomes that make up a human person.

     The added realization that genes affect behavioral traits as well as physical ones means using CRISPR-Cas9 to change human genes is all the more irresponsible.

     My father used to say, "There are no fat Jautzes." Photos of relatives show whether he was right or wrong. They also show where my sister got her red hair. Just as Carl Zimmer wrote in She Has Her Mother's Laugh, we also should pay close attention to family histories of medical problems, such as fractured bones, we might share with ancestors. Looking at traits inherited from members of our family tree explains why our current generation has entrepreneurs, writers, actors, musicians, and only one scientist. In Vogue (March, 2019), I also noticed the Armenian-Syrian singer and composer, Karyyn, reported, "All of my aunts and uncles in Syria on my mom's side are artists, singers, musicians, and puppeteers."

     A young person trying to decide on a career can begin by finding out the professions their ancestors chose. On the PBS TV show that helps prominent people discover their roots, politicians often are amazed to learn of relatives who also were public servants.

     Playing "Where Did I Come From?" is fun. But, unless carefully played, using gene editing to change pieces becomes a very dangerous game.
