My recent column for The Times on the arithmetic behind electric cars:

The British government is under pressure to follow France and Volvo in promising to set a date by which to ban diesel and petrol engines in cars and replace them with electric motors. It should resist the temptation, not because the ambition is wrong but because coercion could backfire.

My column in the Times on recent sensational discoveries relating to human evolution in Africa:

News is dominated by sudden things — bombs, fires, election results — and so gradual news sometimes get left out. The past month has seen three discoveries in Africa that radically change our understanding of a crucial phase in human evolution. For those interested in the common history of all humanity, this should really be among the biggest news of the year.

The first of these discoveries is genetic. Swedish and South African scientists have made the origin of us — modern human beings — an even more mind-bogglingly gradual phenomenon than we used to think. Here is what they found. A skeleton of a boy who died 2,000 years ago at a place called Ballito Bay has yielded a good sample of preserved DNA. He was a Khoe-San, that is to say an indigenous native of southern Africa of the kind once called “bushmen”, who still live in the Kalahari desert.

My review of Chris Thomas's fine book, Inheritors of the Earth:

If human beings were to vanish from the Earth, what would their effect on wildlife have been? A rash of extinctions, a lot of mixing up so that wallabies and parakeets live in England and rabbits and sparrows in Australia, but also — according to Chris Thomas — an eventual doubling in the number of species on the planet: a “sixth genesis”, as he calls it in reference to the five previous times that biodiversity has expanded rapidly after a mass extinction. We are causing a mass speciation.
