The fossil record continues to grow. And with it, so does the contradiction at the heart of the study of human evolution. Each year brings new hominin fossils—jaws, skulls, infant mandibles—that confuse our picture of early human evolution. Instead of revealing a coherent lineage shaped by adaptive refinement, the evidence points to mounting morphological […]

Domestication of Humans: Abduction
Recent observations of white-faced capuchin monkeys on Jicarón Island in Panama have documented a particularly telling case of a broader behavioural theme. Over a 15-month period, juvenile male capuchins were seen abducting infant howler monkeys. They carried them for days, sometimes until the infants died. This behaviour does not resemble caregiving, nor does it fit […]
All gender is male: An ethological perspective
When we observe humanity from a perspective of animal behaviour (ethology), we find something unusual: human females do not look or act like females in most other species. Instead, they exhibit behaviours and characteristics that, in the rest of the animal kingdom, are associated with males competing for mates. This might seem counterintuitive at first, […]
Domestication of Humans: Dispersal
We often hear about the similarities between humans and our closest primate relatives—chimpanzees and bonobos—especially when it comes to social behaviours, like the mother–child bond. These comparisons are used to draw beautiful parallels that make us feel more connected to the animal kingdom, but this often requires ignoring the differences. In this article, I talk […]
Culture and the Myth of Learning
A young chimpanzee, clinging to its mother, will stretch out its hand or make vocal requests for a bite of what the mother is eating. Sometimes, the mother obliges and offers the infant some food; other times, she remains focused on her own meal, leaving the infant to fend for itself. The infant must be […]
Language and human uniqueness
Paleoanthropology, the study of ancient humans, continually revises our understanding of what makes Homo sapiens unique. Initially, the faculty of ‘language’ was thought to be exclusive to modern humans. This view expanded to include Neanderthals as new evidence came to light. Now, even Homo erectus, our ancient ancestor, is considered to have had this capacity. […]
