Characteristics of purine frequency prior to strand breaks.
<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
Amounts of endogenous mtDNA sequences (bp) determined per milligram (mg) of tissue as a function of age.
<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

Mountain gorilla silverback Umushikirano displays with adult female Tuck's corpse
Silverback Umushikirano displays with Tuck's corpse by hitting it in the abdomen with his fist and then he stands in a strut-stance posture. Two blackbacks, Pato and Turakora, embraced and mounted a few meters away immediately following the display. All of the group members continued to rest close by
Grauer's gorilla affiliative and agonistic behaviors toward the corpse of an extra-group silverback
Grauer's gorillas sniffing, poking, licking, and grooming the corpse of an extra-group silverback they discovered in the forest. The silverback Chimanuka displays with the corpse and it rolls several meters down a slope
