"The differences between the two strains turn out to be minor. Both comprise about 30000 nucleotides, making the genome of SARS-CoV the largest of any RNA virus. It is possible but unlikely that the differences are a result of sequencing errors."
"The structural differences from other coronaviruses, and the lack of evidence of recombination, suggest that the SARS virus is not a result of other viruses swapping DNA with a previously benign coronavirus that already lived unnoticed in humans."
"Rather, the researchers say, the evidence indicates that SARS is genuinely new in humans and until recently inhabited an unknown animal species, probably in Guangdong province, China."
