. - [kondwani] i wanna know what breakthroughs are being made. - technologies like crispr are incredibly powerful. - what we're doing here is really the beginning of a true revolution. - that will force the future too. that is incredible. live genetic engineering. (eerie staccato music) (dramatic electronic music) (prosthetic clicking) (water speckles) (robotic arm whirring) (electronic tone beeping) my name is kondwani phiri. i'm a genetic researcher. you could say, it's in my blood. from an early age of about eight or nine or so, i had just a natural curiosity for the natural world. cancer runs in my family. in fact, i lost my aunt to breast cancer. and that peaked my interests in genetics. i'm fascinated by how the genes we inherit shape our biological destiny, including our health. i believe the key to treatments and cures for diseases like these, lies in explicit efforts to engineer human genes. but can we fix not only what's broken but also enhance our genetic codes and improve on mother nature? some day, will humans direct their own evolution and should we?
