Genesis 8:17 - How the ark held so many animals.

Bring forth with thee every living thing that is with thee, of all flesh, both of fowl, and of cattle, and of every creeping thing that creepeth upon the earth; that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth.

How could the ark hold all the world's animals? The answer lies in genetics. The only other place in the Bible (KJV) the word "breed" is used is in Deuteronomy 32:14 to indicate a specific type of ram found in Bashan. In Genetics, the word "breed" is used to refer to a relatively homogeneous group of animals within a species, developed and maintained by humans (from the Random House Webster's Unabridged Dictionary). God gave man dominion over all animals of the earth (Genesis 1:26) and every kind of animal has already been tamed by man (James 3:7). This explains why today we have so many breeds of animals within each species. However, I'm sure that the ark contained only one breed of each species which explains how the ark could hold all the world's animals as we know them today.
