FastTFriend's insight:
Human beings are not obviously equipped to be nature’s gladiators. We have no claws, no armor. That we eat meat seems surprising, because we are not made for chewing it uncooked in the wild. Our jaws are weak; our teeth are blunt; our mouths are small. That thing below our noses? It truly is a pie hole. To attend to these facts, for some people, is to plead for vegetarianism or for a raw-food diet. We should forage and eat the way our long-ago ancestors surely did. For Richard Wrangham, however, these facts and others demonstrate something quite different. They help prove that we are, as he vividly puts it, “the cooking apes, the creatures of the flame.” Delete the scoop?

"Last Human Standing" examines why "we" survived while those other ancestral cousins died out. And it explores the provocative question: In what ways are we still evolving today? Delete the scoop?

We are all members of a very special species. Whilst our anatomy and physiology is undoubtedly that of an ape, we have done things that no other ape can do, and become the most successful ape on the planet. Today, our global population numbers almost seven billion; we survive and thrive everywhere from the tropics to the Arctic. Delete the scoop?

American philosopher Daniel Dennett talks to Carole Jahme about faith, science, empathy – and Short Circuit - This week American philosopher Daniel Dennett, a long-time stalwart of Darwin@LSE, shared his wisdom with a lunchtime crowd in the London School of Economics' Old Theatre. Since fellow philosopher Helena Cronin's 1995 launch of the LSE hub (which is devoted to evolution's maxims) Dennett has been a regular guest. His mission this week to persuade the public that cultural evolution exists and is facilitated due to our hierarchical nature, where those at the top tell others what to think and do. Dennett rhetorically asked, "Does culture make us smart enough to have minds?" From studying the human ability to become good at things without understanding, which then leads to our acquisition of the cognisance to comprehend, via our competence, Dennett favours the theory (first suggested by Richard Dawkins) that our social learning has given us a second information highway (in addition to the genetic highway) where the transmission of variant cultural information (memes) takes place via differential replication. Software viruses, for example, can be understood as memes, and as memes evolve in complexity, so does human cognition: "The mind is the effect, not the cause." Not all philosophers, including Cronin, agree that natural selection shapes culture. But Dennett goes even further, describing a spectrum where, at one end, memes are authorless and free floating and at the opposite end they are guided by forethought, are less Darwinian and more purposeful, such as statistics, computer software and poetry. "Natural selection is not gene centrist and nor is biology all about genes, our comprehending minds are a result of our fast evolving culture. Words are memes that can be spoken and words are the best example of memes. Words have a genealogy and it's easier to trace the evolution of a single word than the evolution of a language." Because Dennett is an approachable, kind man, once his lecture finished I proposed accompanying him to his lunch appointment and asking a few questions en route. Luckily, he agreed. Via Wildcat2030
