Articles
You’ll find here three categories of articles:
(1) Blogs, which I refer to as “strøtanker” (a Danish word), based on my musings and ideas and intended for all who wonder and ponder.
(2) Science articles containing references for further study, based on theoretical and empirical research (more approachable for the beginner student).
(3) Journal-style academic papers that meet the strictest standards for validity and verifiability, with adequate references to allow you to evaluate my findings (for graduate students and fellow scientists).
May you enjoy your reading—and feel free to leave a comment. As a member, you are part of my team, and I value your input.

The Canine Hip Nudge Behavior
The hip nudge is a common canine behavior. Dog owners often think their dogs are pushy or impolite when they turn their backs to them, sometimes even pushing them. Nothing could be farther from the truth. A hip nudge is a behavior a dog shows when it nudges another...

Canine Maternal Behavior
Watching dog mothers take care of their pups continues to fascinate me, after the extensive research my team conducted in the 1980s. The large populations of village dogs in Africa and Thailand, where I spent and spend much time, provide me with plenty...

Facts Versus Ethics: Tail Docking and Ear Cropping
Stating a fact does not oblige me to adopt any particular moral stance. What science teaches me about a fact does not impose any moral stance on me or how I feel about it. It may impact my decision, but my ethical decision is ultimately independent of scientific...

The Canine Twist Behavior
The canine twist behavior is a curious behavior that few dog owners recognize, let alone know what it means. It is a characteristic behavior shown by any canine (wolf, dog, African wild dog, and dingo, at least) when it twists one hind leg out to the side. They...

Laughter Among Humans and Nonhumans
“Laughter is the shortest distance between two people,” Victor Borge once said. As a good Darwinist, I enjoy finding proof that humans are not that different from other life forms. We share many characteristics with the other living creatures with whom we share our...

A Relationship is a Natural Thing
Do you think they fight about what positive and negative reinforcers or punishers are? Do you think they waste precious time arguing about dominance and submission? Do you think they care about collars, leashes, harnesses, target sticks, clickers, kongs—or looking...

I Do Enjoy Being Kind to Other Animals
I do enjoy being kind to animals, other than humans—and I don’t need a rational justification as to why that’s right for me. I respect them for what they are and interact with them on equal terms. I don’t believe it is right to subjugate them to my will, control them,...

The Biggest Difference Between Humans and Dogs
The biggest difference between humans and dogs is not that we reason, and they don’t. If you want to observe rational behavior, look at the dog. If you want to see an emotional response, watch the owner. Some animals, other than humans, do reason. They have...

I’m a Citizen of the World
“I’m a citizen of the World,” I say when asked where I come from—and I am, in mind and heart. Diogenes, in about 412 BC, was probably the first to use the expression and express the very same sentiment. Socrates (469-399 BC) concurred: “I am not an Athenian or a...

“Creation,” the Movie About Charles Darwin—too Controversial for Religious USA?
Creation opened the Toronto Film Festival 2009 and had a British premiere on September 25. The movie relies on the book “Annie’s Box—Charles Darwin, his Daughter and Evolution,” first edition from 2001, written by Randal Keynes, a great-great-grandson of Darwin....
