     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).

3. (psychology, colloquial) The act of experiencing an event by proxy through an empathic link with the person who is experiencing the event firsthand.
