|Once, countless individuals
of this species lived on the ca. 59 km² large Isla Pinta in the Galapágos
Already in the year 1906 their number was shrunk to only four individuals, when the American 'Biologist' Rollo Beck killed three of them to examine their stomach contents.
Today only one individual of this species is still alive, an about 100 year old male that has been named 'Lonesome George'. This animal is now kept in the Charles Darwin Station on the island of Santa Cruz, where (futile) efforts are undertaken to preserve the Pinta Island Giant Tortoise as a species.
'Lonesome George' is the last living member of a species that has to be considered 'technically extinct', because it is impossible, to preserve this species by crossing it with other tortoise forms. On the one hand all of the so far undertaken efforts to associate females of other forms to the lonesome male seem to be fruitless, on the other hand all potential descendants would either way represent nothing but hybrids.
