A Microsoft patent application has evolutionary biologists worried Redmond could claim standard techniques used by scientists to organize how animals are related through time.

The patent application, which came to light in the August edition of Science, claims invention of methods for mapping biological data to an evolutionary tree. It includes methods for counting evolutionary events as well as grouping evolutionary relatedness from biomolecules.

"This patent is written in such a broad language that it appears to swallow up any activity that involves understanding biodiversity though phylogenetics," said William Piel, a phylogeneticst at Yale University quoted in the article.

Piel claims the basic techniques are derived from as far back as when Charles Darwin sketched the first evolutionary tree, and today are used by hundreds of biological systematics software packages. "Microsoft might as well patent the multiplication tables," Piel said.

Because such a patent could potentially hobble an entire scientific field, evolutionary biologists will surely be keeping a closer eye on Microsoft's newfound interest in gene-splicing software. ®
