Whether the newly modeled conditions prevailed long enough to account for all four of the migration events molecular biologists have detected is uncertain, although preliminary data suggest that Madagascar did not move into its present location until some 15 million years ago—well after the last proposed dispersal event. More simulations of ocean currents from different time periods would bolster their case—and hang the landbridge theory out to dry.
