The variability of the Giant tortoises of the Galapagos islands (remote volcanic islands off Ecuador) were one of the examples that convinced Charles Darwin about the phenomenon of evolution. More recently, the sad tale of Lonesome George, the last of the Pinta island Giant tortoises, occurred with him dying in captivity, aged about 100, without a mate. Interestingly, it has recently been reported (https://www.theguardian.com/world/2020/feb/02/galapagos-experts-find-a-tortoise-related-to-lonesome-george ) that 30 hybrid tortoises have been found on Wolf island with Pinta island genes (so they are related to George). It seems likely that, years ago, pirates or whalers, operating in the Galapagos, marooned Giant tortoises from several locations on Wolf island. They were, perhaps, stocking this small island with beasts they could return to eat.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
