%X One hundred and fifty years ago, Charles Darwin¡¯s on the Origin of Species explained the evolution of species through evolution by natural selection. To date, there is no simple piece of evidence demonstrating this concept across species. Chargaff¡¯s first parity rule states that comple-mentary base pairs are in equal proportion across DNA strands. Chargaff¡¯s second parity rule, in-consistently followed across species, states that the base pairs are in equal proportion within DNA strands [G ¡Ö C, T ¡Ö A and (G + A) ¡Ö (C + T)]. Using genomic libraries, we analyzed the extent to which DNA samples followed Chargaff¡¯s second parity rule. In organelle DNA, nucleotide rela-tionships were heteroskedastic. After classifying organelles into chloroplasts and mitochondria, and then into plant, vertebrate, and invertebrate I and II mitochondria, nucleotide relationships were expressed by linear regression lines. All regression lines based on nuclear and organelle DNA crossed at the same point. This is a simple demonstration of a common ancestor across species.
