What do scientists most likely consider as important evidence when classifying an unknown organism?

Scientists most likely consider KNOWN characteristics of KNOWN and named organisms when first classifying an unknown organism. They look for similarities and differences between what is known versus unknown. Major differences exclude known categories; strong similarities include the new organism into a known category. This is how scientists continually build a "family tree" of every organism.
