During evolution, new species can arise from the hybridization of two parental species. Rieseberg et al. (p. 741; see the Perspective by Coyne, p. 700) examined the genomic composition of an ancient hybrid sunflower species and three hybrid sunflower lines created in the lab. Although the three experimentally created lines were synthesized by different crossing schemes, they contain similar combinations of genes. Surprisingly, these experimentally created lines resemble very closely the ancient hybrid species.
