Hi Kate,
When travelling in Peru it was understood even by the natives that llamas were in the camel family.
Yes, but "Family" is not "Species" --"Family" is a much broader category, two rungs up the ladder from "Species."
When you use the term "Species," do you maybe have in mind the Biblical designation, "Kind?" --As in "...of every creeping thing of the earth after its kind, two of every sort shall come unto thee..."
We'll find out how close when we know if the offspring is sterile or not.
This suggests that sterility of the offspring is your yardstick for defining the limits of a "species" (Or kind) Is that a fair observation?
