There’s a great tribute to him on the National Geographic site: https://www.nationalgeographic.com/animals/2018/08/alan-rabinowitz-big-cat-champion-news/ A Brooklyn-born kid who used frequent Bronx Zoo visits to overcome a severe stuttering Read More

Another great Skeptoid episode, this one on race

Posted 09 Jan 2017 / 0

With a lot of mindless computer work to do, I just had time to check out another Skeptoid episode, this one on race (“There’s No Such Thing as Race… Or Is There?“). You can listen to it here: http://skeptoid.com/audio/skeptoid-4546.mp3 Wow, I am really impressed! So frequently when I hear people try to tackle the subject Read More

My personal experience that creationists gravitate to anything with even the faintest scent of scientific uncertainty (and what to do about it)

Posted 22 Dec 2015 / 0

Last month, I published a rather long review of William Provine’s last book, The “Random Genetic Drift” Fallacy. The book is pretty obscure and I knew that a lot of other evolutionary biologists had dismissed the book as being a bit on the crazy side, so in the back of my mind I was wondering whether Read More

Lev Ginzburg Fest: celebration of a “retirement”

Posted 17 Dec 2015 / 0

“Lev Ginzburg has retired”. For anyone who knows Lev, this combination of words does not make a whole lot of sense. Is it possible that such a lively and active scientist would hang up his yellow pad and pencil in order to put his feet up in some retirement community far away from the world Read More

Jeremy Yoder on contemporary selection for increased human height

Posted 23 Nov 2015 / 0

Social Evolution Forum “Natural Selection on Human Height Doesn’t Measure Up To Much” I agree overall with Yoder’s analysis, although it seems that he misreads the study a bit: by my reading, women’s height also had an effect on the survival of offspring, although the effect was nearly half that of men. But Yoder’s larger Read More

Review of William B. Provine’s “The ‘Random Genetic Drift’ Fallacy”

Posted 05 Nov 2015 / 5

Just about a year ago, I got an unusual email. It was from William Ball Provine, a well-known historian of science most famous for his work on the modern evolutionary synthesis. Provine was especially well-known to me as the Ph.D. advisor to Greg Graffin of the punk band Bad Religion; although this is a story Read More

Group phenotypic composition: implications for individuals and their groups

Posted 22 Oct 2015 / 0

Trends in Ecology & Evolution “From Individuals to Groups and Back: The Evolutionary Implications of Group Phenotypic Composition” Man, I wish that this article was written in a more accessible manner, because what it presents is important. There is a critical feedback between how the composition of groups affects individuals and how individuals affect the Read More

Evolution 2014: Day 0

Posted 20 Jun 2014 / 0

I started off this year’s Evolution meeting early. The conference is — at its core —  a four-day affair. But the days leading into the “official” start on Friday evening feature larger workshops aimed at building skills. I chose to attend the Experiencing Evolution workshop. Here’s what this session promised: Evolution is a key biological concept, Read More

Evolution 2014: Cooperative data collection is more meaningful than individual data collection

Posted 20 Jun 2014 / 0

Julie Noor’s classroom activity in Drosophila breeding points out a really great “best practice” for any data collection in undergraduate laboratory exercises: if you ask students to first interpret only the data they collected, then allow them to interpret the aggregated data of the whole class, you can allow them to see the importance of sample size.

Evolution 2014: Students can watch fly populations evolve in a matter of weeks

Posted 20 Jun 2014 / 0

Julie Noor of Duke University shows how a very simple classroom experiment in fly breeding to the F3 generation can force students to answer the following question in the affirmative: “Have you ever seen evolution actually occurring?” It is powerful when students are able to report that they have seen “evolution in action”.
