Eric Holloway: Why is randomness a good model, but not a good explanation?
After all, he argues, random processes are used all the time to model things in science: When we test a sequence of numbers for randomness, we are essentially testing how easy it is to predict the sequence of numbers. One of the simplest tests is to measure how frequently heads and tails occur during a series of coin flips. If the distribution is heavily skewed one way or the other after a large number of flips, then we can be pretty certain the coin is not fair. We cannot be absolutely certain, since there is always a small probability for a really long run of heads, but as the run lengthens, the probability of achieving the run with a fair Read More ›

Responding to Moran – Is “Unguided” Part of Modern Evolutionary Theory?
I am always aghast that in the 21st century people still make the claim that mutations are unguided. This is a hold-over idea from before the discovery of DNA, simply because some mutations were found to occur independently of selection. However, modern evidence has showed that mutations are actually in large part due to mechanisms geared for adaptive purposes, just like the rest of biology. And, just like hearts have heart attacks, mutation systems can break down, too, and lead to disease. Just like bacteria, we discovered mutations first by noting the ones that were causing disease, but with every closer look we see that these are the exception rather than the rule. To point to a simple example (and Read More ›
