“Kinds” of animals on the Ark?

As correct study of Genesis indicates, the Lord did not create the full diversity of Creation during the first six days. Instead, the Bible says He created “kinds.” Kinds (min in Hebrew) are something like species today, which means He created animals that had the potential in their DNA to diversify over time into subkinds.

For example, we can imagine the Lord created a feline “kind” that eventually diversified into various cats and a canine kind that diversified into various dogs, wolves, etc. Therefore, Noah needed only collect a pair of each parent kind and not pairs of every derivative animal.

This understanding of kinds significantly reduces the space requirements on the Ark.
