While waiting for National to reply, and NOT holding my breath, I thought I'd give the community a crack at this.
Preparing for IOLS, I again read SC-4, and pondered on what in the world BSA means by "10 kinds of wild animals (birds, mammals, reptiles, fish, mollusks)"
Mollusks are a phylum. The other four listed are classes in the subphylum Cordata. Strange sort of examples. Like "10 kinds of plants (Edicots, Serbian spruce, Colorado spruce, Norway Spruce, Black spruce)" -- in the sense of different levels of abstraction.
If we are sorting "kinds" at that level of taxonomy, the five listed parenthetically must be merely examples. You can't get to ten with an exclusive list of five. So amphibians are OK. Insects? Worms? I hope so.
"Kinds"? "Kind" is not a conventional scientific term. Since the examples of "kinds" are one phyla and four classes, are "kinds" at that level of abstraction? Examples from ten different phyla / ten different classes? 1. a Bony fish.; 2. a Cartilaginous fish; 3. a Jawless fish - and so on? Or is it ten animals that are different is some undefined way we get to define, thus adding to the requirements?
"Wild" animal. Easy, right? What makes an animal "wild" for advancement purposes? Are feral Felis catus or feral Canis familiaris or feral Quaker Parrots “wild” for advancement purposes? Does it depend on whether they escaped from a pet shop? Is a domesticated Canis lupus or one habituated to man NOT “wild” for those purposes? What if is kills a Homo. sap? If the adjective does not matter, why is it there? Again, we could decide, but . . . .
I pointed out to the advancement team ten years ago that the three fires requirement for WIlderness Survival allows for electric BBQ starters, kerosene blow-torches, thermite grenades, butane lighters, naphtha lighters, railroad flares, and propane torches as not "matches." No action. So every MBC still writes his/her own requirement, differing from place to place (6 volt batteries?). Perhaps we should rejoice in the practical freedom to "roll our own."
