Are thoughts and behavior. determined by heredity (遗传) or by environment? Social scientists have long been interested in this question; the results of "twin studies" are particularly interesting to them.Twin studies of the similarities and differences between twins.There are two types of twins: identical twins, who look exactly the same because they have identical genetic characteristics, and fraternal twins, who have different genetic characteristics.In a 1937 study, Newman, Freeman, and Halzinger found that identical twins are more similar in height and weight than fraternal twins.Because identical twins have the same genetic characteristics, the conclusion was that size is determined more by heredity than by environment.In 1962, James Shields compared the height, weight, and intelligence of identical twins who were brought up together (in the same environment) with those of identical twins brought up apart (in different environments).He found that although the differences were small, identical twins who were brought up together were more similar than those brought up apart.Shields concluded that height, weight, and intelligence are largely determined by heredity.However, because of the differences between identical twins brought up together and those brought up apart, these characteristics may be partly determined by environment.
In the case of Oscar and Jack, heredity seems to determine physical and mental abilities, tastes, and behavior.Environment seems to determine thought.

A controversy erupted in the scientific community in early 1998 over the use of DNA (deoxyribonucleic acid) fingerprinting in Criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a Pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity(父亲的身份) where it is not clear who is the father of, a particular child. However, it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.
DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to prove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.
The controversy in 1998 stemmed from a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass, and Daniel L. Hartl of Washington University School of Medicine in St. Louis, Mo. Lewontin and Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method can- not properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns.
In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K. Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the Federal Bureau of investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples from various ethnic groups in an attempt to resolve some of these questions. And, in April, the National Academy of Sciences called for strict standards and system of accreditation(鉴定合格) for DNA testing laboratories.
Before DNA fingerprinting is used, suspects ______.
A.would have to leave their fingerprints for further investigations
B.could easily escape conviction of guilt
C.would have to submit evidence for their innocence
D.could be convicted of guilt as well
In the sense that his writings described the subtle motivations behind human behavior. as guilt and anxiety resulting from the sins perpetrated (犯罪) against humanity, he adhered to the same moes as his Puritan predecessor. He differed from them in that he saw the potential consequences of all decisions resulting in either the chance possibility of regeneration or some form. of humiliating punishment. This element of ambiguity in his works ran directly counter to the thoughts of his fundamentalish (原较旨主义者) contemporaries who believed that all actions, and their consquences, were predetermined.
As he chose an allegorical style, his short stories were often situated in fantastic settings with unlikely characters. It was not unusual for Satan to appear in his narratives disguised in a human form. but possessing some defining characteristic such as cloven hooves and a tail. What marks these tales as unique to the author's positions their suddestion that there may be contradictory meanings behind the actions of figures which initially appear to be east in transparent roles.
His classic novel, the Scarlet Letter (1850), concerned of the crime, but Puritan community. The heroine, Hester Prynne, stands accused of the crime, but refuses to reveal the identity of her partner. The moral ambivalence (矛盾心理,既爱又恨) inherent in the plot of the work is representative of the themes found throughout Hawthorne's writing.
