Win a $50 VISA gift card for the deemed best answer to this question: Given the pervasive pattern of “sudden appearance” and “stasis” in the fossil record, does science need a Theory of Stasis or Theory of Conservation to better explain how nature actually functions. Explain. How would such a theory help to strengthen an inference to intelligent design? Feel free to hash out ideas here. For possible hints go to: Stasis: Life goes on but evolution does not happen and Law Of Conservation Of Information vs Darwinism Last month’s question was How would you would respond to someone when they claim that Intelligent Design is merely an appeal to a “god-of-the-gaps”? Entry 6 was selected.

For centuries, researchers knew that Euglenids, a diversified family of aquatic unicellular organisms, could reshape their bodies in any number of elegant ways but no one knew why they did it. Some researchers think they now know: “Amongst biophysicists, metaboly was thought to be a way to swim in a fluid, where these cells live,” Arroyo said. “However, protistologists are not convinced by this function for metaboly, since Euglena can swim very fast beating their flagellum, as do many other cell types. Instead, the predominant view is that metaboly [body deformations] is a functionless vestige ‘inherited’ from ancestors that used cell body deformations to engulf large prey. Watching cells executing such a beautiful and coordinated dance, we did not believe Read More ›

They try but somehow the love story just won’t tell itself in a way that makes any sense: It may sound rational to conjecture that love is merely an emergent property of consciousness that has matured throughout the course of human evolution. But emergence is no less of a “god of the gaps” belief than Zeus’s lighting or Thor’s thunder. Zoe is a great film but it presents a storyline often used to show how inexplicable and ineffable love is in order to get me to believe that it isn’t. For example, the underlying dogma assumes reductionism (everything is material). Thus, the question addressed isn’t the obvious one, “Can a synthetic love a human?”; it is “Can a human love Read More ›

Researchers studied the thale cress (an Arabadopsis relative) which can have either a single or a double genome. Genome doubling is not good news: “It’s almost always a bad thing to have too much DNA, but we think that sometimes it makes for a ‘hopeful monster’ that just might flourish.” They seem to have found one: “These tough little plants can become little genetic adaptation machines which allows them to invade hostile environments and even thrive where others can’t. In fact, a large proportion of the most invasive plant species in the world are genome doubled, so we hypothesised that there are adaptations that occur as a result of genome duplication that we can focus on and find the genes Read More ›

He offers some here: When I teach a course, I too like to sell the sizzle at the beginning of each lecture. For a graduate course in information theory I teach, the students are told that they will learn why their cell phones use recently discovered coding that pushes the boundaries of what is mathematically possible in communication speed. I also tell them that we will prove that some things exist that we can also prove are unknowable. And there are numbers that a computer can’t compute. There also exists a single number, Chaitin’s number, that we know lies between zero and one. If we knew Chaitin’s number to finite precision, we could prove or disprove numerous open problems in Read More ›
