My latest Mind and Matter column for the Wall Street Journal is about the exodus from Africa, either 125,000 years ago or 65,000 years ago. Everybody is African in origin. Barring a smattering of genes from Neanderthals and other archaic Asian forms, all our ancestors lived in the continent of Africa until 150,000 years ago. […]
Why do diseases cause species decline?
Matt Ridley
My latest Mind and Matter column in the Wall Street Journal is about the role of disease in species conservation: Some beekeepers, worried by the collapse of their bee colonies in recent years, are pointing a finger this month at a class of insecticide (neo-nicotinoids) that they think is responsible for lowering the insects’ resistance to […]

My latest Mind and Matter column for the Wall Street Journal is on gene-culture co-evolution: Human beings, we tend to think, are at the mercy of their genes. You either have blue eyes or you do not (barring contact lenses); no amount of therapy can change it. But genes are at the mercy of us, […]

One of my favourite writers these days is Willis Eschenbach, whose essays at wattsupwiththat often combine ingenious scientific rationality with lyrical prose. Here he is on the subject of the sea ice off Alaska: My point in this post? Awe, mostly, at the damaging power of cold. As a seaman, cold holds many more terrors […]

Some of the answers are fascinating. Here’s mine: It’s hard now to recall just how mysterious life was on the morning of 28 February 1953 […]
The slow cooling of our interglacial
Matt Ridley
Here’s my latest Mind and Matter column in the Wall Street Journal, with added links and charts. On interglacials. The entire 10,000-year history of civilization has happened in an unusually warm interlude in the Earth’s recent history. Over the past million years, it has been as warm as this or warmer for less than 10% […]

My latest Mind and Matter column in the Wall Street Journal: Coral reefs around the world are suffering badly from overfishing and various forms of pollution. Yet many experts argue that the greatest threat to them is the acidification of the oceans from the dissolving of man-made carbon dioxide emissions. The effect of acidification, according […]

Matt Ridley
My Mind and Matter column for the Wall Street Journal on 1 January 2012 is here: Here’s a New Year’s thought. With some nine million species on the planet, and with each species lasting a million years on average, about nine species will go extinct naturally this coming year (with more, almost certainly, going extinct […]

Here is the Mind and Matter column in the Wall Street Journal, published on 24th December. Which American city has more inhabitants: San Antonio or San Diego? More Germans than Americans get the answer right (San Diego). What about Hanover or Bielefeld? More Americans than Germans get the answer right (Hanover). In each case, the […]
