Let’s see if we’ve figured it out… everything got off the ark, and went in the direction God directed them because He knew some plants and animals would only survive in certain areas. When they encountered huge bodies of water, animals got on large ‘floating mats or drifts’ (all appropriate plant life was growing on the drifts, after all it was a big flood with a lot of debris no doubt), maybe even crossed land bridges in some instances, and some possibly accompanied people who were dispersing also. We’re not absolutely sure of the interpretation of the time involved, but everything multiplied and diversified relatively quick (that certainly happened on a smaller scale in my hometown, and over the last 20 years). And, most importantly, it doesn’t dispute the Bible. Got it!
