The beauty of sewage

Of the Creation Persuasion

The Earth is flat. A full moon leads to more crime. Humans were created less than 10,000 years ago. If you made your way through even the most general of science educations, the above statements should strike you as suspect.

Guilty Planet Is Resurrected.

Greetings! Thank you for visiting the new Guilty Planet (may the old Guilty Planet rest in peace). Before you go thinking that I aim to channel your mother after you walked in the house with dirty shoes, I would like to note that the title ‘Guilty Planet’ is meant to be descriptive, rather than prescriptive.

Some of The Things I Have Gotten Wrong

As a regular reader, you might know that Tet Zoo has been going for over nine years now. I've written about a lot of stuff, I’ve been intrigued and enthused by a substantial number of animals and animal-themed topics, and I’ve been attracted to a variety of controversial ideas and claimed discoveries.

Domestic Horses of Africa

I've said on several previous occasions that domestic animals are far from outside the Tet Zoo remit. On the contrary, I find them to be of great interest, and I think that their diversity, evolution and behaviour is something that we should pay attention to more often.

“Ecomodernists” Envision Utopia—but What about War?

For an in-class exercise, I like asking students: “What’s your utopia?” I tell them that utopias aren’t fashionable these days; “utopian” is generally employed in a derogatory sense, meaning naively optimistic
