What does this mean forMadagascar???• if clades are very old (> 88 my), thenthey probably result from vicariance (i.e.,they were already on Madagascar when itseparated from other landmasses).• if they are younger, then they must havedispersed from elsewhere, and acrosslarge marine barriers.
What is the <strong>Molecular</strong> Clock Hypothesis?TimeGenetic distanceStrictly linear relationship between genetic distance and time
