It means that women have much more choice over their reproduction than they had before.
It's because they have access to family planning, which wasn't available for many people before then.
Who's next?
I'm Mark Walport.
I'm the director of the Wellcome Trust.
And one of the major things that the Wellcome Trust funds is the Wellcome Trust Sanger Institute, which is where a third of the first human genome was sequenced.
My number is £3,000.
And that is what it costs today to sequence a human genome.
whereas the very first human genome, whose sequence was completed finally in 2003, cost £600 million.
So there's been a 200,000-fold reduction in the cost of sequencing a human genome in about the last eight years.
The other enormous changes are in the time it takes to sequence a genome.
So that very first human genome took scientists from all over the world about ten years to sequence.
One run of a machine...
that can sequence now five human genomes takes just two weeks.
This extraordinary change means that we can now apply genome science to really understanding variation between each one of us in health and disease.
we're beginning to see, for example, cancer genomes sequenced.
So many mutations have been discovered which are the cause of human cancers, and for some of these, drugs are beginning to be developed.
It's not only human sequences that we can analyse on a gigantic scale.
We're now able to use genome sequences to identify organisms, to work out how they might cause disease, to identify...
their susceptibility and their resistance to different antibiotics.
