    • 2018 May 17, Hanneke Meijer, The Guardian[1]:
      Such an old origin for parts of Sulawesi would explain its unique biota and high species richness; species would have rafted along on these fragments from worlds since long lost (a process known as vicariance).
  2. (geology) The geological event which produces such a barrier (volcano, earthquake, etc)
  3. (psychology, colloquial) The act of experiencing an event by proxy through an empathic link with the person who is experiencing the event firsthand.
