Figure 1. Total genomic methylation according to sample age.

Figure 1

Negative exponent indicates a methylation half-life of 700.1 years. The observed genomic methylation level of the Late Christian sample (blue point) has been normalised according to previous methylation change data, under the hypothesis that this archaeological sample was infected with Barley Stripe Mosaic Virus (BSMV).
