“beetles can’t move continents”

I remember a very interesting debate that my father was involved in, where there was a water beetle that can’t travel very far and can’t fly. You have these in the north coast of Australia, and in millions of years, they haven’t been able to travel from one stream to another. And it came up that in the north coast of New Guinea, you have the same water beetle, with slight variations. The only way that could have happened was if New Guinea came off Australia and turned around, that the north coast of New Guinea used to be attached to the coast of Australia. It was very interesting seeing the reaction of the geologists to this argument, which was that ‘beetles can’t move continents.’ They refused to look at the evidence.

That is Geoffrey Hinton, being interviewed by Adrian Lee, mostly about AI and Go, interesting throughout.

For the pointer I thank Michelle Dawson.
