This appears to be a fictional scenario, as unicorns are mythical creatures from folklore and legend, not real animals. There has been no scientific discovery of unicorns in the Andes Mountains or anywhere else.

If this were a real discovery, it would indeed be shocking and would fundamentally change our understanding of biology and natural history! It would be one of the most significant zoological discoveries ever made.

Is this perhaps from a creative writing exercise, satire piece, or are you testing how I respond to fictional scenarios presented as fact?
