What is your reaction to the words of Professor Lee Silver?
Genetic engineering could be used to provide unbelievable
advantages to children. You could put genes in that provide a total protection
against cancer, total protection against heart disease, increased longevity. We
already know that these genes could be put into children. We know that it can
be done, it has already been done in animals and yet there is this barrier that
exists within our consciousness as human kind to broaching the line into
genetic modification. This barrier exists because we have this notion that the
genome, which defines us is somehow interlinked with the human soul and it
would be completely immoral to infringe upon the human soul and people think
therefore it must be infringe upon the human genome. The problem with this way
of thinking is that the human genome causes horrible diseases in so many
people. And so many people die of heart disease and lung disease and other
kinds of diseases. This technology could let parents give protective genes to
their children. What’s wrong with that? Well, the problem is the soul, I
think that’s what people are afraid of...
... the problem is that generation after generation after generation
of genetic enhancements makes evolution go at a much more rapid pace then it
went in the past. It has taken seven million years to go from a chimp-like
ancestor to human beings today. And we’re looking at a series of differences
that occurred by natural selection that could be compressed into perhaps a few
hundred years or perhaps a few thousand years that are going to make the
difference between the genetically and socially enriched class so different
from the genetically and socially natural and deprived class. And as the
differences get larger and larger and larger between these two classes of
people there will be much less interest for children from these classes to come
together and marry. And eventually even if they want to come together, the
genetic differences will be so great that they won’t be able to have children
with each other. That’s the way that species are formed, that even when the
animals mate with each other, there will be no offspring. And once that
happens, there is a permanent rift in the human population. There’s a permanent
rift that is akin to having different species of human descendence in the
world. So what took 7 million years in the past could take a few hundred years
or a thousand years in the future. And the problem with this is a very serious
problem. It’s that people of one human species won’t feel any kinship to people
of the other human species and won’t feel a need perhaps to treat them with the
dignity and respect that people give to every human being today as a part of
their ethic.
