Nach Panda-Porno jetzt auch noch Schildkröten-Sex. Bald gehen mir die Alliterationen aus.
According to the Guinness Book of World Records Lonesome George, a native of Pinta, an isolated northern island of the Galápagos, is the "rarest living creature." By the late 1960s, it was noted that the tortoise population on this island that is visited only occasionally by scientists and fishermen, had dwindled close to extinction, and in 1972, only this single male of the species Geochelone abingdoni was found.

Bis vor kurzem hat man angenommen, dass Lonesome George wirklich und unumstößlich der letzte lebende Vertreter seiner Art ist. Aber in der Current Biology-Ausgabe vom 30. April berichten Wissenschaftler*, dass es möglicherweise doch noch Hoffnung gibt, eine weibliche Pinta-Schildkröte zu finden.
New research led by biologists Adalgisa Caccone and Jeffrey Powell in the Department of Ecology and Evolutionary Biology at Yale, with the strong support and cooperation of the Galápagos National Park and Charles Darwin Research Station, has identified a tortoise that is clearly a first generation hybrid between the native tortoises from the islands of Isabela and Pinta. That means, this new tortoise has half his genes in common with Lonesome George.

Aber offensichtlich ist Lonesome George nicht sonderlich interessiert an Sex.
George is not what you would call a stud. When I visited him in 1985, he was thought to be a relatively young adult, maybe 50 years old, but he was already a confirmed bachelor. He hadn’t shown any interest in two females of a similar species placed in his pen. One had flipped over and drowned in the wading pool. The keepers weren’t positive that George had driven this tortoise to her death, but he definitely hadn’t been doing any Barry White serenades.

A few years later, in 1993, there was briefly a companion known as “Lonesome George’s girlfriend,” but she was not a tortoise. She was a 26-year-old graduate student in zoology from Switzerland named Sveva Grigioni.

By coating her hands in the genital secretions of female tortoises and gently stroking him, she managed to demonstrate a couple of times (in the course of several months’ work) that George was capable of an erection. But whereas her touch could induce other male tortoises to reach orgasm within a few minutes, with George she never managed to collect any sperm. [...]

If Eve [Anm.: eine weibliche Pinta-Schildkröte als Partnerin für ihn] is found, humans just have to do a little more work. George needs to be primed. Sending Ms. Grigioni back to work would be a start, and George could also learn by watching other males in action, as some biologists have proposed. Dr. Nicholls even raises the possibility of showing instructive videos to George — and if tortoise porn is what it takes, I say go for it.

"Instructive videos" für Schildkröten? Na, ob das hilft, wenn schon Schweizer Handmassagen keine Resultate erbringen...
