If you find Acronym Required's 2008 Thanksgiving fare too glum, here's an excerpt from 2007:
The Spaniards fancied the turkey when they invaded Mexico where turkey was indigenous, and then introduced the bird to Europe when they returned in the early 1500's. However, during the expansion of the Ottoman Empire, turkeys were thought by northern Europeans to be a product of Turkey.
Europeans also for a time called turkeys "India fowl", then confused the turkey with "Guinea fowl" and gave turkeys the same Latin genus name: "Maleagris". The species name that they settled on, "gallopavo" combines the Latin for rooster and for peacock. From these confusing origins turkeys have long struggled with their identity. First they were put in their own family, Meleagrididae; but now scientists consider turkeys to be part of the pheasant family, Phasianidae, in the subfamily Mealeagidinae.
