I am looking for simple way to tell if blood stain is from human blood or some other animals. I know there are fluorescent DNA dyes, but is there dye that only attaches to human DNA?

    $\begingroup$ I highly doubt it: human DNA and DNA from other species are very similar in structure, and in some cases (eg: primates) are very similar as sequences as well. I think that "complex" analytical techniques are necessary in order to tell human DNA from animal DNA. $\endgroup$

    $\begingroup$ It would have to be a superintelligent dye. $\endgroup$
