More on swimming tortoises

by Greg Mayer Dennis Hansen, our Aldabra correspondent, sent Jerry a very nice video of a swimming Aldabra giant tortoise (Aldabrachelys gigantea). This immediately brought to mind what is, in my view, one of the most important recent papers in biogeography, “The first substantiated case of trans-oceanic tortoise dispersal” by Justin Gerlach, Catharine Muir, and […]

Spot the wood frog

My Minnesota correspondent found this fellow along Caribou Trail (a road) and Jonvick Creek near Lutsen, Cook County, Minnesota, about a half mile from the north shore of Lake Superior, on 10 […]

Island faunas and the Falkland Islands fox

Darlington, perhaps the greatest zoogeographer of the 20th century, said that zoogeography showed Darwin evolution. And Jerry has long insisted that biogeography is at least among, if not the, most persuasive evidence for evolution. It was thus with great […]

Solenodons on the BBC

(There is another living species of solenodon in Cuba.) Here’s what they look like. The BBC pursued them along with Dominican and British scientists, breathlessly recording their hopes of […]

The Geography of Tapirs

by Greg Mayer Although far from the longest chapter in WEIT, I find the chapter on biogeography the single most persuasive one for showing why evolution is true.  I think Jerry finds it compelling as well. This might seem surprising since he’s a geneticist: one might think he would find some of the genetic evidence […]
