An excellent survey from The Logic of Science, with striking examples. At every level of detail, the family trees inferred from morphology match the trees established by molecular biology.
Many people are under the false impression that evolution is just a guess or a belief, when in reality, it is one of the most well-supported concepts in all of science. The evidence for it is overwhelming and comes from many different disciplines such as paleontology, comparative anatomy, biogeography, and perhaps most significantly, genetics. Indeed, modern genetic tools have allowed us to repeatedly test evolution’s predictions, and those predictions have consistently come true. Therefore, I am going to explain in simple terms what the genetic evidence is and why it is so compelling. As I will show, the evidence perfectly matches the predictions that the theory of evolution made decades before we could test those predictions. Further, the patterns do not make sense if our modern organisms were specially created, because there is no reason why a creator would have had to make life with these patterns. In other…

Evolution has nothing to do with progress. Most evolution doesn’t even have anything to do with adaptation, and it is perfectly possible for a change that is worse than useless to spread through a population. Paradoxically, however, such non-adaptive change may be a necessary prelude for major adaptations.
This post was inspired by a recent opinion piece (open access here1) in BMC Biology, entitled “Splendor and misery of adaptation, or the importance of neutral null for understanding evolution” (I will explain what “neutral null” means later). The paper itself is in parts highly technical, with 86 references to the original scientific literature, but I will try here to give a general overview of some of the main conclusions, and to place them in context.

Darwin and Wallace both thought that evolution was driven by selection. If so, then whenever we find a feature in an organism, Read the rest of this entry
How Darwin’s name is taken in vain, with mini-reviews of some of the worst offenders. And when I wrote about this last year, I did not expect to have to add a US Vice-President to their number.
Charles Darwin never thought of evolution as anything other than a theory. He hoped that someday it would be proven by the fossil record but did not live to see that, nor have we. – Representative (now Vice-President) Mike Pence, 2002, via Forbes
Trump’s Education Secretary Nominee DeVos Should Challenge Darwinism* – David Klinghoffer, CNS, 13 January 2017 
Don’t say Darwin unless you mean it. Don’t say theory when you mean historical fact. And don’t say you believe in evolution, when you mean you accept it on the basis of the evidence.
Don’t say Darwin unless you mean it. Above all, don’t say “Darwin” when you mean “evolution”. It’s like saying “Dalton” when you mean atoms. Our understanding of atoms has moved on enormously since Dalton’s time, and our understanding of evolution has moved on similarly since Darwin’s. Neither of them knew, or could have known, anything about what caused the phenomena they were talking about, and both would be delighted at how thoroughly their own work has been superseded.

The story so far: Our petition attracted over 700 signatures, some notable, and Spencer Fildes and I were invited to give evidence on it before the Public Petitions Committee last November (shown above; see here for more). After submitting us to attentive but not unfriendly cross-examination, the Committee decided to write to a number of interested parties, whose submissions you will find on the petition website, together with my own response. It met again last Thursday, to consider what action to take, and the official report is now available here under Continued Petitions, and reproduced below for completeness.
Now read on: We had hoped that at this point they would decide to forward the matter to the Education and Skills Committee, going down much the same road as a related petition did three years ago. What happened, however, was potentially far more favourable to our case. It is relevant that the Convener is Johann Lamont, a very senior, independent-minded, and able parliamentarian, who has said of herself “I have been a committee convener, proud of building consensus where possible, to test legislation and to challenge the government of the day.” Read the rest of this entry
If you want to know more about Socrates, or Humanism, or anything else that really matters, this is for you.
And the horns of Euthyphro’s Dilemma, described here, are as sharp as ever. This morning, February 2nd, a committee of the Scottish Parliament is considering the Scottish Secular Society petition for the removal of the church representatives who sit, immune from electoral scrutiny, on Scottish Local Education Authority Committees. Defenders of the status quo argue that they have an important role to play in transmitting Christian values. The petition (which I helped write) argues that if a value is specifically Christian, it will not necessarily be shared by the non-Christians who now form a majority among young Scots, while if it is not specifically Christian, we do not need a church representative to instruct us in it. The derivation from Euthyphro is obvious.
More on the petition on this blog and on the Parliamentary website. Updates as available. Massimo Pigliucci’s essay, below, speaks for itself, and I am flattered that he approves the use that the petition made of Socrates’ argument.

As part of my ongoing occasional series aiming at bringing some of my own technical papers to the attention of a wider public (after all, what the hell is the point of doing scholarship if it only benefits other scholars?), below I reprint a paper I recently published in The Human Prospect. It inquires on the possibility of interpreting Socrates as a proto-Humanist of sorts, and it therefore includes a discussion of Humanism as a philosophy of life, as well its likely stemming from the ancient Greco-Roman tradition of virtue ethics (via the mediation of the Renaissance Humanists, which were informed by, and yet were reacting against, medieval Christianity).

Answers in Genesis recommends Liberty University, of which Jerry Falwell is president, because
One of the unique features of Liberty is its strong stance on the literal creation account in Genesis. Every Liberty student is required to take a course called “History of Life.” The faculty of the Center for Creation Studies, led by Dr. David DeWitt, teaches this course. The arguments for biblical creation are drawn from science, religion, history, and philosophy.
The course textbooks, as Dr DeWitt describes them on the Creation Ministries International website, are Refuting Evolution by Jonathan Sarfati, and The Creation Answers Book (Sarfati et al), which tells you among other things, how all the animals fit into the Ark and why radiometric dating is unreliable.
Liberty University has some 15,000 on-site students, with a further 100,000 on-line, and claims to be the largest Christian university in the world. Forbes ranks Liberty #651 among US Universities, and its graduation rate (48%) is among the lowest for private universities. However, the Young America Foundation places it among the top 10 choices for conservative students. Glasgow readers may remember it as the alma mater of Pam Stenzel, who told horror stories about sex to Catholic school children bussed in to hear her (more here and here). Read the rest of this entry
