Is the genomic revolution an overhyped flop or are we on the edge of a life changing revolution? How has it changed the way we practise medicine, grow crops and breed livestock? What have we learned about evolution? These are the questions science writer and molecular biologist Elizabeth Finkel asked herself. To find the answers she travelled the science frontier from Botswana to Boston, from Warracknabeal to Mexico and tracked down scientists working in the field. Their stories, told here, paint the picture of what it means to be part of the genome generation.
