    <p><b>A:</b> Base frequencies 5′ and 3′ of 5′-ends of endogenous mtDNA fragments of a horse (sample 54). <b>B:</b> Increase in purine frequency at position immediately 5′ (position −1) of mtDNA fragment ends relative to positions −5 to −10 as a function of age. Nine samples known to have been “roasted” over fire and treated with ponal glue are indicated by crosses and four samples treated by the “Leipzig cocktail” are indicated by circles. <b>C:</b> Increase in A (blue) and G (red) frequencies at position −1 of mtDNA fragment. Nine samples known to have been “roasted” over fire and treated with ponal glue are indicated by crosses and four samples treated by the “Leipzig cocktail” are indicated by circles.</p

    <p>Note that since the Neandertal specimens were all ascertained for containing endogenous DNA they are excluded from this analysis. Nine samples known to have been “roasted” over fire and treated with ponal glue are indicated by crosses and four samples treated by the “Leipzig cocktail” are indicated by circles.</p
