 Dwi wedi bod yn gweld y tro cyfnodd. Mae'r tro cyfnodd, mae gennym yn ymdweud ar gyfer ffist a ffamon. Mae'r tro cyfnodd wedi bod yn ymdweud, mae'r tro cyfnodd effaith yn ymdweud, ac mae'r tro cyfnodd yn ymdweud ffasol. Yn mynd i chi i ddim yn ymdweud ymdweud, byddwn i'r tro cyfnodd gyda maen nhw, ac mae'r tro cyfnodd yn ymdweud. Llywodraeth. In theolithic times we were all in Africa chewing meat with huge jaws. And sometimes hunting meat was dangerous and hard and we did a lot of starving until we discovered wild cereals that were happily just sitting around waiting to be eaten. They were tough and not very tasty until we discovered the technology to turn them into flour and porridge. ac ydy'n ddweud y gweld gwahanol yw'r prosiect, felly rwy'n bwysig i'w cmfodol gweithredu gwahanol. Rwy'n 12,000 o'n fydd, rwy'n gweld i'w ddweud yw gyntaf yw Afriadau. A oes i'r ddefnyddio, byddwn ni wedi'i gael yn fath o gyfrifol a chyflwmpio a'r ddefnyddio i'r ddweud ystod yn gyfrifol. Yr ystod, rwy'n gilyddio i'r ddweud yw Lacto'i teimlo sy'n ddweud i'r ddweud hynny'n gilyddio'n ddweud. Because we just weren't getting enough Vitamin D from our diet of cereals. So cereals are responsible for the shape of my face, the colour of my skin, my ability to drink elate. Now, neolithic farmers quite sensibly around the world were selecting the big three cereals of rice, wheat and maize for bigger seeds easier harvesting and threshing. Ysgol yn ymerhaeth geneddyg hwn yn gwneud bod ydych chi'n sgol ffasgyraedd gŵr yn ymddangos. Ac ydych chi'n gweithio'r gweithio'r gweithio yn gweithio'r gweithio. Mae'r gweithio gyda'r ddweud hyffordd yn ymddangos i'r hybridd i ar 3 mhwyaf. Mae'r hybridd yn ymddangos i gyd, gan ychydig o'r cymhwyr i'r gwaith a'r gyfrillol, all in one, that's a hexaploid. So it's hardly surprising then that Mary Shelley's mythical monster Frankenstein stalks our very debate about how we move our relationship with plants forward. I want us to rethink this relationship because in the last 10 years we have achieved quite astonishing understanding and control of plant and animal genomes over life itself. And also, as you heard in the last talk, it's actually become astoundingly accessible. You can download the components for biosynthesis off the internet and I discovered in September that my son's school friends do genetic modification in their lunch breaks. So we really need to embrace this technology and use it to tackle the world's major challenges of cleaning up the environment and feeding the world's growing population because it's something we've been doing for millennia, but it's really important that we do it intelligently and collaboratively and above all ethically. And remember Frankenstein was not bad, he was just misunderstood. Thank you.
