Computer composer

An article about classical composer David Cope and the AI programs he wrote to make original music. It's not new news, but a nice profile with many "what does it mean to be creative?" moments.

Cope had taken an unconventional approach. Many artificial creativity programs use a more sophisticated version of the method Cope first tried with Bach. It’s called intelligent misuse — they program sets of rules, and then let the computer introduce randomness. Cope, however, had stumbled upon a different way of understanding creativity.

In his view, all music — and, really, any creative pursuit — is largely based on previously created works. Call it standing on the shoulders of giants; call it plagiarism. Everything we create is just a product of recombination.

I'd call it "culture". The long-term direction may look random, but "styles" cohere over time because people take from each other. The article's leitmotif is Cope's near-Quixotic quest to write a truly life-changing piece of music. It's ironic that he discovers how to make music that humans can't tell from yesterday's classics, but tomorrow's classics will be determined by those very same human arbitrers of taste.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
