Did you know that animals have built-in algorithms? Some of these amazing algorithms allow animals to migrate to new places and navigate back to previous locations. Insects also have a wide variety of fascinating social behaviors. Where did they come from? Eric Cassell, author of Animal Algorithms, discusses animal algorithms, artificial intelligence, instincts, and irreducible complexity with Robert J. Marks. Read More ›
An algorithm is a step-by-step procedure to perform a specific task. We usually think of algorithms as being performed by computers. Did you know that animals have built-in algorithms of their own? Some of these amazing algorithms allow animals to migrate to new places and navigate back to previous locations. Eric Cassell discusses his new book, Animal Algorithms, with Robert Read More ›
My friend and colleague Casey Luskin has penned a poignant essay in memory of Richard Lewontin, a Harvard evolutionary biologist who passed away at 92 recently. Casey is a gentleman and a scholar, and very much disposed to finding the best in people. Indeed it seems there was much that was very good in Lewontin’s persona, and Casey highlighted it beautifully in his encomium. I am not of the opinion, however, that we should speak only good of the dead. The passing of a public figure is a good time to consider his impact, and Lewontin’s impact on American culture and science is something very much worth considering. By all accounts, Lewontin was a gentleman and a good friend and Read More ›
Naturalism, the idea that physical nature is all there is, can lead us down some strange paths. In the words of prominent philosopher Daniel Dennett and prominent biologist Michael Levin, both of Tufts University, the road to “biology’s next great horizon” is the attempt to “understand cells, tissues and organisms as agents with agendas (even if unthinking ones).” They think that the principle of natural selection acting on random mutations can create everything, including minds: Thanks to Charles Darwin, biology doesn’t ever have to invoke an ‘intelligent designer’ who created all those mechanisms. Evolution by natural selection has done – and is still doing – all that refining and focusing and differentiating work. We’re all just physical mechanisms made of Read More ›
Bugs look like little robots, don’t they? Living robots, too, defying our best our attempts to recreate something like them. A 2018 science paper “It’s Not a Bug, It’s a Feature: Functional Materials in Insects” goes into just how amazing these little creatures are from a materials sciences perspective. The paper is open access so you can read it for yourself. But let me also illustrate some of the remarkable “technologies” insects use, captured on video: This bionic “dragonfly” really flies, sort of: But so do billions of wild dragonflies who fly very efficiently, in order to hunt: The range of material capabilities is astonishing. Cicadas have a clicking loudspeaker they use to amplify their racket. Tiger moths have a Read More ›
In college, I hated Plato. We read his Republic, and, as a patriot and an idealistic young (small “d”) democrat, I was appalled at the hegemony of the Guardians and at Plato’s disdain for democracy. It seemed to me that his Guardians were the archetypal totalitarians, and that it was a fundamental human right — enshrined in the Constitution — to be ruled only by consent of the governed. In my dotage, I am more sympathetic to Plato — it’s remarkable how much smarter the old philosopher has gotten in the past 40 years! I am still uncomfortable with Guardians, at least of the secular sort. But I think John Adams got it right when he observed that “our Constitution Read More ›
The critical problem that consciousness poses for Darwinian evolution is that there is no survival advantage for subjective first-person existence over objective third-person existence.
