a theory (obviously unproven and unprovable) mentioned in passing that I found particularly intriguing - that the (in)famous tameness of many island species, causing them to fail to flee from newly arrived humans or invasive species that are able to kill them in large numbers, might not be naivety about new predators but rather, that their passivity is an evolved, adaptive trait in response to living in a restricted environment - basically that the same suite of genetically linked changes that causes tameness and physical size changes in domestic animals is also at work on island animals.

Ahhh fascinating!
