Although there are about 668 names of dinosaurs, there are perhaps only 55 different "kinds" of dinosaurs. Furthermore, not all dinosaurs were huge like the brachiosaurus, and even those dinosaurs on the Ark were probably "teenagers" or young adults.

Creationist researcher John Woodmorappe has calculated that Noah had on board with him representatives from about 8,000 animal genera (including some now-extinct animals), or around 16,000 individual animals as a maximum number. When you realize that horses, zebras, and donkeys are probably descended from the horse-like "kind," Noah did not have to carry two sets of each such animal. Also, dogs, wolves, and coyotes are probably from a single canine "kind," so hundreds of different dogs were not needed.

According to Genesis 6:15 , the Ark measured 300 x 50 x 30 cubits, which is about 510 x 85 x 51 feet, with a volume of about 2.21 million cubic feet. Researchers have shown that this is the equivalent volume of over 500 semitrailers of space. 1

Without getting into all the math, the 16,000-plus animals would have occupied much less than half the space in the Ark (even allowing them some moving-around space).

So...if he carried a starter species that would descend into various species of today...maybe evolution actually WORKS!?
