The secret of zebra stripes solved—or so scientists say

Over the past five years I’ve written several posts on the long-standing and vexing question, “Why on earth do zebras have stripes?” (See posts here, here and here.) If you’ve read those posts, you’ll know about the experiments that seemed to settle the issue, or at least that gave a good indication of the evolutionary forces that promoted the […]

Jesus ‘n’ Mo ‘n’ brain scans

Today’s Jesus and Mo strip, called “drugs” is based on a Daily Mail report on functional magnetic resonance imaging (fMRI) of the brains of 19 “devout Mormons” (what—no other faiths?). When the Mormons were scanned while undergoing religious experiences, like reading scripture or watching Mormon videos, the fMRIs (which show blood flow to various parts of the […]

Readers’ wildlife photos

Reader Joshua Lincoln sent us some lovely photos of damselflies; his notes are indented: My friend Wally once said that birds are a gateway drug for dragonflies.  I don’t think that it could be put any better than that. I will include some Anisopterans (dragonflies; aniso=different ptrery=wing; the front and back wings are different in […]

Wednesday: Hili dialogue

Good morning! Ii’s Wednesday, crassly known as “hump day”, January 18, 2017. It’s Gourmet Coffee Day (that does not mean double caramel macchiato lattes with whipped cream), Peking Duck Day, and also the first day of the Week of Prayer for Christian Unity.  I doubt anyone reading this will be praying for such a thing—or praying period. […]

Monster gator in Florida

Readers Michael (and contributor Matthew Cobb) sent a video of a monster American alligator (Alligator mississippiensis) crossing a path near Tampa, Florida. It was estimated to be 13-15 feet long, but they can get up to 20 feet. As you can imagine, it’s gone viral on social media.

The lichen story and the guy who revised it

A story I wrote in July of last year described a huge change in our understanding of one of the best known cases of symbiosis: the view that a lichen is a symbiotic partnership between a fungus and an alga. That happens to be true—the alga photosynthesizes, producing food for the fungus, while the fungus provides support, […]

Eight people have as much money as the poorest half of the world

When I talked to Dave Rubin yesterday morning, he asked me, if Americans are so resistant to the facts of evolution, what could I do to get people to accept it as truth? I told him that we’d have to get rid of those forms of religion (read: most religions) that make people resistant to evolution, […]

Turkish government removes evolution from nation’s high-school curriculum

“I have no religion, and at times I wish all religions at the bottom of the sea. He is a weak ruler who needs religion to uphold his government; it is as if he would catch his people in a trap. My people are going to learn the principles of democracy, the dictates of truth […]

Trump enters office with lowest approval rating of any recent President: 40%!

In just three days we’re going to have to choke out the words “President Trump”. And while there’s a small and deluded group of people who really do think they can prevent his taking office, I’m betting on his inauguration on Friday. (Of course, I bet about $500 that he wasn’t going to win in […]
