I am a crab and I have evolved at least five separate times, but no one knows why

Underwater scene with migrating crabs and other small marine creatures among colorful coral reefs

We are present around the world, in every ocean, in some lakes, even on dry land.  We are an old, proud order having shared the world with the dinosaurs 200 million years ago, but some of us aren’t even true crabs. They are imposters that have evolved separately, over and over again. I am a… Continue reading I am a crab and I have evolved at least five separate times, but no one knows why

Our brains might have more in common with an octopus than we’d like to believe, suggesting that famed evolutionary biologist Richard Dawkins’ new paradigm is correct

Almost everyone knows that an octopus is much smarter than we would expect for a boneless creature that lives in the ocean, but next to no one expected they would achieve their intelligence using some of the same genes and chemical processes we do. Octopi and their cephalopod cousins have long been regarded as unusually… Continue reading Our brains might have more in common with an octopus than we’d like to believe, suggesting that famed evolutionary biologist Richard Dawkins’ new paradigm is correct

The evolution of consciousness and the omnipresence of sentience

Based on the latest research, we can continue to maintain that sentience, and the higher order consciousness that springs from it in humans, is the most widespread accident in the history of life, completely unnecessary, but somehow omnipresent, or we can reject that view and assume it serves a deep evolutionary purpose. Thought experiments can… Continue reading The evolution of consciousness and the omnipresence of sentience

The shape of your inner ear, convergent evolution, and the evolution of evolvability

A new study from the University of Vienna on the inner ear in mammals offers valuable evidence and insight, while upending at least some of the conventional wisdom by finding the shape of the ear in some lineages is more directly connected to habitat and lifestyle than genetics alone. Counter intuitively, we can find evidence… Continue reading The shape of your inner ear, convergent evolution, and the evolution of evolvability
