Marshall points out that the
relatively fast appearance of
new animal species in this period is not driven by
new genes, but rather by evolving from existing
genes through «rewiring» of the
gene regulatory networks (GRNs).
But an explosion in powerful «
gene - editing» techniques, which enable
relatively easy and selective tinkering with genomes, raises a niggling question: why go to the trouble of making

new DNA, termed horizontal
gene transfer, was thought to be
relatively rare and to occur only under strong pressures in the environment, such as exposure to powerful antibiotics.

Other medical sequencing projects will use DNA sequencing to: discover
new genes that are involved in common diseases; identify the
genes responsible for dozens of
relatively rare, single -
gene (autosomal Mendelian) diseases; sequence all of the
genes on the X chromosome from affected individuals to identify those involved in sex - linked diseases; and survey the range of variants in
genes known to contribute to certain common diseases.

genes.
