How Cooking Made Us Human with Professor Richard Wrangham

Humans are the only animals that cook their food. One of the implications of cooking food, as noted by Oliver Goldsmith is, “of all other animals we spend the least time in eating”. In a ground-breaking theory of our origins, primatologist Richard Wrangham argues that the shift from raw to cooked food was a key factor in human development. When our ancestors adapted to using fire, humanity as we know it, began. Wrangham notes that as a result of eating cooked food, the human digestive tract shrank and the brain grew. Eating cooked plants or meat makes digestion easier and the energy we formerly spent on digestion was freed up, enabling our brains to grow. Cooking increases the proportion of nutrients that can be digested, makes food easier to digest and kills pathogens (harmful bacteria and viruses). Time once spent chewing tough food could be used instead to hunt and undertake other tasks and activities. Cooking became the basis for pair bonding and marriage, created household and shaped family structures, and even led to a gender based division of labour.

Richard Wrangham is a professor of Biological Anthropology at Harvard University and founded the Kibale Chimpanzee Project in 1987. He has conducted extensive research on primate ecology, nutrition, and social behaviour. In his book “Catching Fire: How Cooking Made Us Human” Wrangham argues that cooking food is obligatory for humans as a result of biological adaptations and the cooking, in particular, the consumption of cooked food might explain the increase in human brain size, smaller teeth and jaws, and smaller more effective digestive system. Wrangham’s “Catching Fire” presents an interesting narrative that how we came to be the social and intelligent beings that we are today.

“Cooking was a great discovery not merely because it gave us better food, or even because it made us physically human. It did something even more important: it helped make our brains uniquely large, providing a dull human body with a brilliant human mind” – Richard Wrangham

Complement this with slightly different but equally interesting discussion “Robots, Artificial Life and Technology Imagined by the Ancients” with Adrienne Mayer.

“Irrationality: A History of the Dark Side of Reason” with Professor Justin Smith

In his new book, “Irrationality: A History of the Dark Side of Reason” philosopher Justin Smith presents a fascinating narrative that reveals the ways in which the pursuit of rationality often leads to an explosion of irrationality. Smith, a professor of the history and philosophy of science at the University of Paris, acknowledges that we are living in an era when nothing seems to make sense. Populism is on the rise, pseudoscience is still around and there is no shortage of of conspiracy theories. Smith discusses the core of the problem that the rational gives birth to the irrational and vice versa in an endless cycle, and any effort to permanently set things in order sooner or later ends in an explosion of unreason. He notes that despite the fact logic and reason are well understood, methods and practises that were supposed to have been setup to counter irrationality, ended up mired in the very problem that they were meant to solve, and that is irrationality.

“Irrationality: A History of the Dark Side of Reason” is rich and ambitious and ranges across philosophy, politics and current events. It challenges conventional thinking about logic, natural reason, dreams, art and science, pseudoscience, the Enlightenment, the internet, jokes and lies and death and shows how history reveals that any triumph of reason is temporary and reversible, and that rational schemes often result in their polar opposite. Smith argues that it is irrational to try to eliminate irrationality and describes irrationality an ineradicable feature of life. It has been an absolute pleasure speaking with Professor Justin Smith in this episode of Bridging the Gaps. This has been a fascinating conversation.
