1. There have been endless unsolved biological problems, and far too few scientists to study them.
    有无数未解决的生物学难题，研究它们的科学家还远远不够。

2. There is general agreement that genuine biological differences exist between individuals; geniuses need to be lucky in both their genes and their parents.
    人们普遍认为，个体之间存在着生理差异，要成为天才必须幸运地既拥有天才的基因，又拥有能造就天才的父母。

3. The most significant implication would seem to be that while most people are in a good position to fulfill their biological potential — barring serious illnesses or a poor diet during childhood — it is far from certain that they will grow up in an en
    最重要的启示似乎是：尽管大多数人都有条件很好地发挥他们的生理潜能 --即除非童年时得了严重疾病，或饮食太差，他们肯定能充分发展自己的基因遗传能力，但是，他们是否能生长在一个能开发其能力的环境中则远非一个确定因素。

4. An amazing fact: Dolly has no biological father.
    一个有趣的事实是：多莉没有生物学意义上的父亲。

5. Another advance, a computer-controlled brain scanning device, has led to a second discovery by those seeking the biological component of mental abilities.
    另一进展，一台计算机控制的脑部扫描仪，使得寻找思维能力的生理因素的研究人员有了第二个发现。
