This is Hidden Brain. I'm Shankar Vedanta.
Some months ago,
I brought seven key insights from the first decade of Hidden Brain to live stage performances in San Francisco and Seattle.
The evenings were electric.
We got so much positive feedback from those two sold-out shows that we've decided to launch a tour.
to more than a dozen cities in the coming months.
I'll be coming to Portland, Denver, Minneapolis, Chicago, Austin, Dallas, Boston,
Toronto, Clearwater, Fort Lauderdale, Phoenix, Baltimore, Washington, D.C., and Los Angeles.
To snap up your tickets, please go to hiddenbrain.org.
You can also sign up to say hello and get a photo with me.
In some places, you can sign up for an intimate chat with me and a handful of other fans.
I'd love to see you there.
Again, go to hiddenbrain.org slash tour.
Okay, on to today's show.
This is Hidden Brain.
I'm Shankar Vedantam.
The 19th century naturalist and biologist Charles Darwin is best known
for developing the theory of evolution by natural selection.
He described the theory in his book On the Origin of Species,
one of the most important publications in the history of science.
