How were the animals for the ark gathered? It is clear from the scriptures referenced on the slide that BOTH Noah and God were involved.

The "Divine Filter" indicates that God made the final decision about which pair of individuals of each type boarded the ark. One reason for this is that only God could know the genetic potential of each candidate, and it would be important that the individuals having the greatest genetic potential serve as the "founding pair" in repopulating the world. Some of the animals were probably chosen by God directly from the wild.

However, Woodmorappe postulates that Noah may have kept a menagerie (a collection, like a zoo) of animals in preparation for the ark. It is important to remember that Noah had a long time to prepare (up to 100 years). He may have even paid people to help gather the animals. With such a menagerie Noah could be sure he had individuals that adapted well to captivity (the "Tolerance to Captivity Filter"), and that exhibited gentle, "non-nervous" behavior (the "Behavioral Filter"). In addition, he could have performed breeding experiments to help determine which individuals would be best suited as parents for repopulating the world (the "Genetics Filter").
