【单选题】
A、GayBiologist
Molecular biologistDean Hamer has blue eyes, light brown hair and a good sense of humor. He smokes cigarettes, spends long hours in an old laboratory at the US National Institute of Health, and in his free time climbs up cliffs and points his skis down steep slopes. He also happens to be openly, matter-of-factly gay.
What is it that makes Hamer who he is What, for that matter, accounts for the talents and traits that make up anyone’s personality Hamer is not content merely to ask such questions; he is trying to answer them as well.A、pioneer in the field of molecular psychology, Hamer is exploring the role genes play in governing the very core of our individuality. To a remarkable extent. his work on what might be called the gay, thrill-seeking and quit-smoking genes reflects how own genetic predispositions.
That work, which has appeared mostly in scientific journals, has been gathered into an accessible and quite readable form in Hamer’s creative new book, Living with Our Genes. "You have about as much choice in some aspect of your personality, " Hamer and co-author PeterCopeland write in the introductory chapter, "as you do in the shape of your nose or the size of your feet. "
Until recently, research into behavioral genetics was dominated by psychiatrists and psychologists, who based their most compelling conclusions about the importance of genes on studies of identical twins. For example, psychologist MichaelBailey of Northwestern University famously demonstrated that if one identical twin is gay, there is about a 50% likelihood that the other will be too. Seven years ago, Hamer picked up where the twin studies left off, homing in on specific strips ofDNA、that appear to influence everything from mood to sexual orientation.
Hamer switched to behavioral genetics from basic research; after receiving his doctorate from Harvard, he spent more than a decade studying the biochemistry of a protein that cells use to metabolize heavy metals like copper and zinC、As he was about to turn 40, however, Hamer suddenly realized he had learned as much about the protein as he cared to. "Frankly, I was bored, " he remembers, "and ready for something new. "
Homosexual behavior, in particular, seemed ripe for exploration because few scientists had dared tackle such an emotionally and politically charged subject. "I’m gay, " Hamer says with a shrug, "but that was not a major motivation. It was more of a question of intellectual curiosity — and the fact that no one else was doing this sort of research. \
Hamer was a ______.
A、psychiatrist
B、physiologist
C、chemistD、biologist
