taming genes

Some mistakes turn out to be beneficial. And life, or its survival, has always thrived on them. Add a few mutations to a genome, drench it in time, and you have the driving force of evolution. Transposons - these bits of DNA that are able to skip along genomes - are just one kind of mutation that has contributed hugely towards life's unfolding…
