In October 2011, the World Health Organization announced that tuberculosis cases are on the decline for the first time in at least 20 years. Our battle against this ancient disease has been fought, in part, through the use of antibiotics like streptomycin. This news brief describes the 1.8 billion year evolutionary history behind these drugs.

- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- The early evolutionary process of eukaryotes included the merging of prokaryote cells.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
