For most of the 21st century he had positioned himself as part of the right wing of the transhumanist movement. He returned to Russia after living in California's Bay Area for several years, and from there he promoted a nationalistic vision in opposition to American military and cultural power. With the February 2022 invasion of Ukraine, he joined a chorus of Russian warbloggers cheering on the inevitable conquest.

And then, like Richard Hanania, he did an about-face on...

  During the Ice Age our ancestors often painted the horse in caves

On this week's episode of Unsupervised Learning Razib covers the archaeology, genetics and history of the horse. Dogs may be man's best friend, but for thousands of years horses were humanity's most valuable domesticate. While pigs, cattle and goat were essential elements of the world's subsistence economies, the horse in its military roles was a luxury good, with Chinese emperors sending delegations to Central Asia in search of "heavenly steeds."

But while dogs have been humanity's sidekick for at least 20,000 years, and cattle and caprids for...

In the exchange, Dibble, a vigorous online critic of pseudo-archaeology came back with sci...

On this episode of Unsupervised Learning Razib talks to Akshar Patel of The Emissary about his recent sojourn in India. Patel began The Emissary because he felt there were many gaps in the media representation of India. Razib asks whether The New York Times' claim that Modi is a strongman is correct, and whether India is an illiberal democracy.
