Suppose we identified genes that made people more docile and tolerant of crowding? Should't we exploit that knowledge and improve future generations of humans?
That is the premise of Genetically engineering 'ethical' babies. Actually, since we are not able to assemble the perfect baby, gene-by-gene, perhaps we should be screening the embyros. Professor Julian Savulescu argues that since we already screen embryos for procedures such as in-vitro fertilization (IVF), that we should extend the type of screening to more of the world's embryos before they mature.
Mmm. Generation and destruction of life is a slippery slope, isn't it? The result of two teenagers' passion can be a baby. How is that ethically or morally superior to the thoughtful and deliberate genetic engineering of a baby?
