Quintessence of Dust

Quintessence of Dust explores science, society, and human nature, focusing on genetics, development, evolution, neuroscience, systems biology, and topics related to scientific literacy. I occasionally discuss intelligent design, creationism, science denial, and other political/social influences on scientific literacy. Additional topics: philosophy, baseball, scientific culture, and Shakespeare. My main theme is scientific explanation.

I've reviewed a few books over the years here at Quintessence of Dust , but From Extraterrestrials to Animal Minds: Six Myths of Evolution by Simon Conway Morris was the first book I blogged through that I was genuinely excited about reading.

That's one of two epigraphs at the beginning of Chapter 6 of From Extraterrestrials to Animal Minds: Six Myths of Evolution , "The Myth of Extraterrestrials," by Simon Conway Morris. It seemed odd to me when I started reading the book, but it makes some sense now that I've made it to the end.

Before I explain the rot at the heart of this chapter (Chapter 5 of From Extraterrestrials to Animal Minds: Six Myths of Evolution , "The Myth of Animal Minds," by Simon Conway Morris), I'd like to show you my workspace as I sullenly trudge toward the end of this task. That's my fun little Chromebook 2-in-1, and the barely-visible tartan mouse pad is from my dad.

It's one of the most famous misquoted lines in the English language, spoken by Lady Gertrude (Hamlet's mom) during the intense scene featuring a play ("The Mousetrap" aka The Murder of Gonzago) within a play, intended by Hamlet to be "the thing wherein I’ll catch the conscience of the King." The character in "The Mousetrap" has delivered some sappy lines about commitment and widowhood, designed to flush out the King and Gertrude.

There are some truly vexing and annoying myths of evolution. They are almost exclusively recited and embellished by religious propagandists, some of whom actually know what they're doing. Rarely but notably, there are myths that are gleefully repeated by creationists while being amplified by scientists who should know better.

If you read about natural history, even just popular accounts, you know about the epic mass extinctions visited on the living world throughout life's tenure on Earth. Words like 'devastating' and 'catastrophic' barely capture their scale—the most thorough purge is called The Great Dying and extinguished at least 95% of the species on the planet. And this isn't just animals dying. It's whole lineages dying.

The concept of randomness is caught up in evolution, in two broad ways. The first and most famous aspect is the oft-misunderstood randomness of mutation. The second aspect is the role of chance in the trajectory of evolution. It is this question—is evolution predictable, or is it a random "drunkard's walk"—that Conway Morris tackles in the second chapter of From Extraterrestrials to Animal Minds: Six Myths of Evolution.

Warning: this post includes spoilers for Black Widow , Avengers: Endgame , and Spider-Man: No Way Home . Seems a small price to pay to understand the biophysical limits of the biosphere, but it's your call. So, are you sure you want that superpower? Have you noticed that superheroes usually have difficult lives and crushing responsibilities?

Which superpower would you choose and why? This seems a somewhat common "get to know you" question. Sometimes you're forced to choose between two (invisibility or teleportation?), perhaps to reveal particular features of your psyche. My choice is teleportation — I want to see my kids and grandkids but I want to live in Edinburgh.
