Antigens encoded by var genes are major virulence factors of the human malaria parasite Plasmodium falciparum. Here, Larremore et al. identify var-like genes in distantly related Plasmodiumspecies infecting African apes, indicating that these genes already existed in an ancestral ape parasite many millions of years ago.
