New research by Professor Dan Graur shows that only a quarter of the human genome is functional.
Is race a trivial quality of humans, or of deep social importance? Who gets to decide whether race exists or not?
How many different races are there? Pick a number, any number, says philosophy professor Philip Kitcher. Wherever there is an agenda there is a division to be made; race is a social construct with scientific levers. "If there’s one thing that we’ve learned from biological science and psychological science over the last century, it’s that there’s an enormous amount of variation within the groups that we’ve traditionally thought of as races, far more than there is between the groups we’ve traditionally thought of as races." This makes sense; historically, we've drawn the line wherever it has suited the mainstream agenda. Humanity can be divided into two races, which would see Africans, Europeans and most Asians as one unified race. Or it could be divided into three races, which would separate Africans into their own group. You can keep dividing humanity down into more and more refined biological groups until you have 10 or 20 or 30 different races. But what would be the purpose? Our mistake has always been confusing groups for classes anyhow. Philip Kitcher is the co-author of The Seasons Alter:How to Save Our Planet in Six Acts.
Harvard bioethics specialist Glenn Cohen considers the complex question of whether humans should mix their genetic material with other animals to create chimeras.
It is really, really fun when Harvard professors play ‘What If…’. This is a regular part of Glenn Cohen’s work as a law professor specializing in health policy, bioethics and biotech. Invoking the Jurassic Park rule of ‘just because you can, doesn’t mean you should’ and imagining all eventualities is how Cohen explores the fascinating and sometimes twisted intricacies driving our ethical dilemmas.
