Oldest Intact Red Blood Cells Found on Iceman

sciencehabit writes "A team of researchers has zoomed in on two spots on the body of the Iceman, a mummified, 5300-year-old hunter found frozen in the Alps in 1991: a shoulder wound found with an embedded arrowhead and a hand lesion resembling a stab wound. The scientists used atomic force microscopy, a visualization method with resolution of less than a nanometer, to scan the wounds for blood residue. They discovered red blood cells — the oldest in the world to be found intact — as well as fibrin, a protein needed for blood to clot. The presence of fibrin indicates that the Iceman, nicknamed Ötzi, didn't die immediately after being wounded."

Yes, it does, really. They researched this. Humans are the only mammal with a glans shaped like ours, and in simulations it proved to be dramatically more effective at removing recently deposited semen than the glansless penii of other primates.
