What key factor necessitated relying heavily on molecular analyses during the classification of Kiwa hirsuta?

Answer

Superficial morphological resemblance to other groups like Galatheoidea due to convergent evolution

When classifying *Kiwa hirsuta*, researchers encountered a situation where general body shape might have tentatively suggested placement near the Galatheoidea (squat lobsters). However, the text emphasizes that in extreme environments like hydrothermal vents, convergent evolution—where unrelated organisms develop similar traits due to adapting to similar pressures—is common. Therefore, relying solely on external morphology was deemed insufficient. Molecular analyses and genetic sequencing were essential to definitively solidify its unique position within the Kiwaidae family, confirming it as a distinct evolutionary branch off the main path of other vent crustaceans.
