Thank you...after enlarging the page I can actually read the caption now.Per the caption for Figure 1, "red, one hit one genome, orange, multiple hits one genome, dark blue, one hit multiple genomes, blue, multiple hits multiple genomes." I take that to mean that the red indicates that there was one hit (match) for one genome only, namely the sheep, and that orange meant that there were multiple hits (matches) for one genome only, again namely the sheep. The blue colors meant that there were one (dark blue) or multiple (blue) hits (matches) for multiple genomes, namely humans, cows, goats, and sheep. Since mammals share a good number of genes, I am not surprised. In fact I had expected it to be higher than it was. The histograms represent parchment 1 (17th century) and parchment 2 (eighteenth century).
That is how I, a senile Texas Aggie, read the figure.
I suspect they limited it to only humans and ruminants and/or omitted non-human non-ruminant results.Since mammals share a good number of genes, I am not surprised. In fact I had expected it to be higher than it was.
