Article: What can genetic engineering accomplish?

ABSTRACT

Many arguments critical of genetic engineering presuppose that it is capable of creating individuals of a specified type or with particular qualities. Recent investigations of neural development yield data which reveal that there are good reasons to believe this assumption is false. These studies have produced a significant body of research showing that experience and environment following birth powerfully shape the brain's structure and the ways it functions. This result implies that the genetically identical brains of two different individuals will likely develop in markedly different ways, and thus that they will have different abilities and personal ...
