【题目】The debate over whether personality is determined by nature has taken a further twist after scientists found adoptive parents have a greater influence on personality than directly genetic inheritance (遗传) from birth parents. 【1】

The research measured personality by placing the zebra finches (斑雀) in a new environment and counting the number of places they visited. 2 Male and female birds were then paired up (配对) and allowed to breed.

The eggs of each pair was adopted by another pair just before hatching (孵化). 3 The size of young birds was also measured and was found to be primarily genetically inherited from birth parents and not influenced by adoptive parents.

Dr. Nick Royle from the University of Exeter said: 4 Because they show that, for zebra finches, personality is primarily determined by the environment they experience after hatching.

He added: Although this study considers personality inheritance in zebra finches, it raises questions about the inheritance of personality in other species, including humans. 5

A. Some were shy, staying mainly in one place while others explored widely showing a more outgoing personality.

B. Researchers at the University of Exeter used the zebra finches to investigate how personality is transferred between generations.

C. Our research findings are therefore surprising.

D. This experiment show that behavior can be non-genetically transmitted from parents to child.

E. Most previous studies have found personality to be genetically inheritable.

F. Personality of young birds was measured once they were adults.

G. Do adopted children inherit the personality characteristics of their birth parents or their adoptive parents?
