Ravens mated another species into oblivion, their twisted family tree shows.
Common ravens in California look like other ravens. But their mitochondria contain a genetic jumble. Mitochondria, the tiny power-plant organs within animal cells, carry their own sets of DNA. Animals — humans and ravens included — inherit mitochondrial DNA from mothers. The mitochondrial DNA in ravens revealed a “deep genetic divergence between two different lineages,” Omland said.
