There it is

The microbial ecologist Jessica Green once pointed out to me that microbiologists typically put two cells in the same species if their ribosomal DNA is 97% identical. Applying the same criterion to primates, she says, and you'd be sharing a species with the ring-tailed lemur.

…Here's some advice for anyone agonizing over creating a perfect, all-encompassing species concept: chill out. Pretty much any biological category you care to think of has fuzzy boundaries. Genomics is making the concept of the gene more problematic. Colonial, clonal and modular organisms, such as slime moulds, aspen, and the vast underground mycelia of some fungi, make the concept of the individual tricky to pin down. The giant mimivirus blurs the line between viruses and cellular life. There's been a long debate over whether viruses themselves should be classed as living things. And it's proved impossible to come up with a list of properties that unambiguously define life.
