How a dog sees and navigates the world

In many ways a dog navigates the same world as we do with shared systems and processes across our senses, but in others their reality is dramatically different with a sense of smell so powerful they can count molecules in the air and see ghosts. I can’t be the only dog lover who frequently looks… Continue reading How a dog sees and navigates the world

ChatGPT and the physics evolution built into our brains

Next generation chat software that delivers a more realistic conversational experience, can do research, and write stories has set the technology and media worlds on fire, but beneath the surface ChatGPT reveals one of the things that makes human intelligence so unique.  We have physics built into our brain by evolution. The technology and media… Continue reading ChatGPT and the physics evolution built into our brains

Could you be an unconscious zombie and not even know it?

As humans, we live in a world of feeling, that is our experience of the world always feels like something either good or bad, but does it truly have to be that way and, perhaps more importantly, why is it that way in the first place?  The only way to answer the question is to… Continue reading Could you be an unconscious zombie and not even know it?

Big breakthroughs in the evolution of the brain and its connection to the stomach

The human brain is the most complex object in the known universe, but key parts of its evolutionary history, from the earliest brains and nervous systems on the planet to more recent changes in our lineage, remain shrouded in mystery.  New studies shed light on both ends of the spectrum, answering an over one hundred… Continue reading Big breakthroughs in the evolution of the brain and its connection to the stomach

There’s a lot to be thankful for

This Thanksgiving, it is too much to ask that we cast off the bonds of our evolutionary heritage for good, but it should not be much to let the better angels of our nature have free reign for a single day.  Friday, let the complaints and battles continue again, but Thursday, set it all aside… Continue reading There’s a lot to be thankful for

Decision-making, community, and the evolution of intelligence

All living things from the simplest bacteria to ourselves make decisions, but not all decisions are created equal.  Some are based on simple chemical reactions, or are driven by inflexible rules governing behavior, while others require complex intellectual machinery that ultimately leads to intelligence.  Our own decision making journey began three million years ago and… Continue reading Decision-making, community, and the evolution of intelligence

The increasingly cold grip of fall and the horror of near endless winter

There’s no doubt fall can be beautiful and the first arrival of cold weather invigorating, but trees don’t lose their leaves because they want to.  Energy is scarce in winter, and all living things have been shaped by the timeless evolutionary challenge of how to spend it wisely, even ourselves. Unlike many, I can’t bring… Continue reading The increasingly cold grip of fall and the horror of near endless winter

Key moments in humanity’s early and more recent history remain written in our DNA

Two new studies illuminate long standing mysteries in our evolutionary and cultural history.  Why were early humans smarter and more adaptable than our Neanderthal cousins even though their brains were about the same size?  When and where did the earliest Indo-European languages emerge leading to what about half the world speaks today?  DNA is a… Continue reading Key moments in humanity’s early and more recent history remain written in our DNA

Humans walked the earth millions of years earlier than we believed and your teeth might be the scales of a fish

A new analysis continues to confirm Charles Darwin’s hypothesis that the first step towards humanity was walking upright, and his thoughts on the matter in Descent of Man still ring true over 150 years later, an incredible feat.  Meanwhile, other scientists are finally beginning to solve the riddle of where teeth came from.  It’s Darwin’s… Continue reading Humans walked the earth millions of years earlier than we believed and your teeth might be the scales of a fish

The Big Bang: The scientific establishment strikes back

Confronted by obvious, measurable, and specific flaws in the theory, proponents in the scientific establishment revert to the usual tactics of appealing to authority, misdirection, and smearing those who disagree.  We might call this the “Dr. Fauci Dodge,” reserved for real card carrying experts. It’s a story that has become all too common in recent… Continue reading The Big Bang: The scientific establishment strikes back
