Whitey Bulger has finally been convicted of a small percentage of all the bad things he is said to have done. The Boston Globe has the details. James J. “Whitey” Bulger, the notorious Boston gangster who rampaged through the city’s underworld for decades before slipping away from authorities and eluding a worldwide manhunt for more…

Does parasite load really matter?

In behavioral biology there is a fair amount of attention to individual quality, which may be determined by genes or parasite load or energy balance, or some interaction among these (and other) factors. Individual quality is honestly indicated by some trait or behavior; a large bright thing hanging of your head, a long bout of…

Humans appear to have a great deal of variation in sexual orientation, in what is often referred to as “gender” and in adult behavior generally. When convenient, people will point to “genes” as the “cause” of any particular subset of this diversity (or all of it). When convenient, people will point to “culture” as the…

The Kiss

Valentine’s Day is coming up, so it is time to think about kissing. Pursuant to this, Sheril Kirshenbaum, author of “The Science of Kissing,” has made the Kindle version of her excellent book available at a discounted price through February 18th. The book is here: The Science of Kissing: What Our Lips Are Telling Us.…

Human infants require more care than they should, if we form our expectations based on closely related species (apes, and more generally, Old World simian primates). It has been said that humans are born three months early. This is not accurate. It was thought that our body size predicted a 12, instead of 9 month…

Darwinian Psychology, or really, any “Psychology” that claims to be science, will operate under the assumption that the human brain, as an organ, has arrived at its modern form through the process of evolution, which includes a certain amount of design through Natural Selection. It does not take that much additional sophistication to realize that…

How Girls Evolved to Shop

Rebecca Watson gave the following talk at Skeptcon. It is funny, well done, and critiques a Pop-Evol-Psy concept or two, which I have also addressed (Why Do Men Hunt and Women Shop?, Understanding Sex Differences in Humans: What do we learn from nature?, Falsehoods: Human Universals, A Tutorial in Human Behavioral Biology, Driving The Patriarchy:…

Manspace

In an old colonial-looking restaurant that served ten kinds of steaks, I met up with an experienced explorer and a local farmer, to have dinner and discuss plans for an upcoming research project that would be managed by The Explorer and that would partly be on The Farmer’s land, which adjoined a rather extensive and…

Why Do Men Hunt and Women Shop?

The title of this post is, of course, a parody of the sociobiological, or in modern parlance, the “evolutionary psychology” argument linking behaviors that evolved in our species during the long slog known as The Pleistocene with today’s behavior in the modern predator-free food-rich world. And, it is a very sound argument. If, by “sound”…

Nature is a potential source of guidance for our behavior, morals, ethics, and other more mundane decisions such as how to build an airplane and what to eat for breakfast. When it comes to airplanes, you’d better be a servant to the rules of nature or the airplane will go splat. When it comes to…
