We Didn’t Get Smarter, We Just Got Together

The main function of these posts is to interpret new scientific findings in the paradigm of human evolution portrayed in this blog. In the last few months, I have lapsed in keeping up with breaking developments in the field because I have been busy writing an essay on the subject, having posted some of the …

A Liberal Theory of Human Nature – Part V: Upright Posture, Great Big Brains and Only One Hand Ax

Filed under: cognitive capacities, Evolutionary psychology, Group Selection, Language | No Comments

For a fossil to be designated a hominin there must be evidence of upright posture.  However, any orthopedic surgeon can tell you that upright posture produces extreme vulnerability for injuries to the lower back (perennially among the top ER visits), hips and knees, so it is reasonable that the evolutionary advantages of such a costly …

A Liberal Theory of Human Nature – Part IV: The New Narrative of Human Evolution

Filed under: Evolution of Emotion, Evolutionary psychology, Group Selection, Human Nature, Justice, Language

Forth in series: click for first, second, or third There is evidence that, in a period of sharply declining temperatures, a collapse in the ape population occurred at the time hominins split off from apes. My view is that in the context of birthrates falling toward extinction, hierarchical dominance competition became a dangerous waste of …

Third in series: click for first or second (two more coming) I entered the field of psychiatry forty-seven years ago imbued by Jung’s theory of a collective unconscious. Jung felt that Freud’s concept of his superego was an attempt to make the collective unconscious personal instead of “universal and deeply historical.” As I began to think …

Second in a series: Click for first or third It is not generally understood that there is virtually no scientific knowledge about how the mind of apes evolved into our own mind. Huge amounts of scientific knowledge about the minds of apes and humans (particularly children) are neatly being stacked upon the cliffs on either …

A Liberal Theory of Human Nature – Part I: The Conservative Narrative

Filed under: Evolutionary psychology, Group Selection, Human Nature

First of a series: click second Political beliefs both start and end with attitudes toward human nature. The right has long been associated with the Hobbesian view that the natural state of mankind is “warre of every man against every man—Bellum omnium contra omnes” (Leviathan, 1651).

Since my retirement 10 years ago, Ape Mind, Old Mind, New Mind has been a work in progress. The basic ideas arose from my knowledge of the internal experience of the major mental illnesses directly imparted to me by thousands of my patients in 35 years of practicing psychiatry. The “data” of these composite descriptions …

Sexual selection, modern humans and the enigma of vanity.

Filed under: Evolutionary psychology, Human Nature, Sexual Selection

Excerpt from forthcoming edition of Ape Mind, Old Mind, New Mind: There is paleontological evidence for sexual selection. What makes early human fossils recognizably modern has less to do with brute survival than with the attractiveness of males and females for each other. Modern human adults are more gracile and childlike, which is the result …

The Role of Emotion (and domesticated animals) in Human Evolution, excerpt from Introduction

Filed under: Evolution of Emotion, Evolutionary psychology

We belong to the primate order of the mammalian class of the animal kingdom. A distinguishing characteristic of primate evolution is the manner in which their large brains were acquired. There is wide agreement that these outsized brains were evolved not in response to the outer physical environment but to the inner environment of an …

Monogamy, Sexual Selection, Temperament and Human Evolution (excerpt from the book)

Filed under: Evolution of Emotion, Evolutionary psychology, Monogamy, Sexual Selection

Some monogamy facts: 85 percent of birds, 3 to 9 percent of mammals—but fully a quarter of mammals’ primate component—are classed as monogamous. Selected species of primates began evolving monogamous social systems about 16 million years ago, relatively late in their 52-million-year history of group living. In each case, monogamy grew out of a promiscuous mating …

From this week’s Science (Vol.355:1299-1301) is an article entitled “How ‘you’ makes Meaning.” The abstract: “You” is one of the most common words in the English language. Although it typically refers to the person addressed (“How are you?”), “you” is also used to make timeless statements about people in general (“You win some, you lose …

Trump: Justice vs. Dominance

Filed under: Evolutionary psychology, Human Nature, Justice, The Ascension of the Human Spirit | 1 Comment

The “radical” conservative philosophy being introduced by the Trump administration is old hat to Darwinian evolutionists. This is the philosophical strain flowing from Nietzsche to social Darwinists through Ayn Rand into Paul Ryan. It supports the businessman’s belief that he is the winner of life’s competitive contest is like the alpha male in a troop …

A glaring weakness of the agenda of the political left is that social justice does not appear to be rooted in the flesh and blood of human nature. The two most influential thinkers on our attitudes about what makes us tick are Charles Darwin and Sigmund Freud: we are ape-men who when psychoanalyzed are revealed …

The Blog has stated before that the philosophical difference between the political left and right have their roots in their different views of human nature. This very moment of transition offers the philosopher of human nature a rare opportunity to have the distinctions on display. Thomas Hobbes expressed attitudes human nature popular on the political …

The New York Times ran a story last week about “going flat” after breast surgery. With no idea of how it relates to such a decision, I thought it might be useful to frame-out one aspect of the evolution of human breasts according to the Blog’s two-mind paradigm. This one aspect concerns the fact that …

This Blog is based on the premise that there was an evolutionary “metamorphosis” in the mental and emotional sphere that gave rise to our hominin “tribe” six million years ago. Pushed by harsh climates and the threat of extinction, the target of natural selection shifted from the fitness of individuals to the productivity of relationships. …

The Evolution of Emotion Precedes the Evolution of Cognition This blog proposes that the primary innovation of our own 200,000-year Homo sapiens species occurred in the emotional sphere and consisted of a marked increase in the motivation for “display” behavior, the function of which can be compared to the emotion-and-motivation of a peacock to display …

An Evolutionary Analysis of Infidelity

This week the blog tackles the biological relevance of infidelity, apparently the next big campaign issue. First, in order to stay focused on the blog’s contribution to this wide-ranging topic we must narrow it down to just a categorical analysis of extramarital sex (while married), disregarding judgements about how it was conducted (discretion, hurtfulness and …

Science from a peculiar source indicates that our bodies have been hairless for at least 3.3 million years. The DNA of the lice that infest our head hair has a continuous ancestry for 12 million years, well prior to appearance of our hominin tribe six million years ago. However, the lice that reside on our …
