Origins of old lineages in New Caledonia: A geologically informed test of the island‐hopping hypothesis
International audience Although New Caledonia (NC) is now considered an oceanic island that emerged ca. 60 Ma, a few terrestrial clades are significantly older, raising the question of the origin of these groups. Classically, old lineages on more recent islands are hypothesized to originate through...
