God made living things to reproduce according to their kind. The taxonomic science of baraminology seeks to classify modern and fossil organisms within their original kinds.

The Bible’s first use of this word (Hebrew:
min) is found in Genesis 1 when
God creates plants and animals “
according to their kinds.” It is used again in Genesis 6 and 8 when God instructs Noah to
take two of every kind of land-dwelling, air-breathing animal onto the ark and also in God’s command for the animals to reproduce after the Flood.
==============================================
So if there were only a
kind of dinosaur aboard the Ark, it had to be the ancestor of the hundreds or thousands of the different dinosaurs we see in museums today. But since the Earth is only 6,000 years old, modern theories about evolution will have to be rethought.
