How do we know when people are actually happy?

Posted 15 Jan 2016 / 0

Image courtesy of Wikimedia Commons Science “Conservatives report, but liberals display, greater happiness” This paper was published back in March, but I just discovered it. I am somewhat fascinated by psychological studies of happiness, because happiness is so hard to pin down. What is happiness, and can we rely on people to accurately report how Read More

Is there a trade-off between reproduction and creativity?

Posted 12 Jan 2016 / 0

One of the ideas that I am exploring in my work-in-progress book Breeders, Propagators, & Creators is that human beings face a fundamental trade-off between three activities: Breeding: behaviors that lead to the production of offpsring (which might — but does not necessarily — include parenting); Propagating: behaviors that spread existing cultural ideas; and Creating: behaviors that introduce 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

Is family-linked terrorism a cultural and genetic phenomenon?

Posted 03 Dec 2015 / 0

National Public Radio “In Worst Attacks, Terrorists Often Have Fraternal Bonds” This is an interesting — albeit brief — piece on a recent “pattern” that has emerged in terror attacks: teams of attackers are often composed of blood relatives. As a good scientist I have to point out that there’s a danger here of over-generalizing Read More

Urban Wildlife Podcast on Cats and Coyotes

Posted 20 Sep 2015 / 0

Urban Wildlife Podcast “Episode 4: Cats and Coyotes” What I really enjoyed about this particular episode of the Urban Wildlife Podcast was the interaction between topics covered. The effects of both cats and coyotes are still largely unknown, even as both animals are fairly common in urban areas. Domesticated cats are pretty easy to track Read More

EnviroAtlas is now live, publicly available

Posted 30 May 2014 / 0

For the past couple of years I have been playing around with a really cool tool called EnviroAtlas, a project of the U.S. Environmental Protection Agency. This past semester I created two classroom activities that use EnviroAtlas, implementing them for the first time in my Ecology for Architects course. The EnviroAtlas tool was in beta-testing Read More

Cognitive Ethology and Cat Companionship

Posted 17 Mar 2014 / 0

The Chronicle of Higher Education “Animal Magnetism” I still think that we would be appalled and offended if we could literally read the inner emotional dialogue of a cat, but I have to agree with the main contention of Barash and Lipton: that animals have feelings and connections with each other — and sometimes with Read More

Understanding the cascading effect of carnivore loss… before we lose all the carnivores

Posted 25 Jan 2014 / 0

NPR Morning Edition “When Big Carnivores Go Down, Even Vegetarians Take The Hit” Science “Status and Ecological Effects of the World’s Largest Carnivores” Both of these articles are great for introducing the idea of trophic cascades as well as how trophic inefficiency implies that large predators require large ranges containing abundant prey.

New fossil finds provide unique insight into the variation found in “Man the Hunted”

Posted 25 Oct 2013 / 0

The New York Times “Skull Fossil Suggests Simpler Human Lineage” It is interesting how terrible fossils are: generally, they represent only a part of one individual who was part of one population in one place at one point in time. Not the best data ever! So when some predator(s) on hominids dumps five carcasses in the Read More

Is human genetic research being hampered by a failure to share data?

Posted 19 Jun 2012 / 0

PLoS One “Mine, Yours, Ours? Sharing Data on Human Genetic Variation” This problem reminds me a little bit of a similar problem in computational biology: often modelers are reluctant to share their code, considering it proprietary information (although note that code represents “methods” and sequences represent “results”). But if gene sequences and model code are Read More
