Hello to you, too, DbaF!! Welcome to EvC!
Rats and mice breed very fast. One single rat can give birth to 20 young a year, that’s 4 to six every 4 to 5 weeks.
Don't you think that might have been a little problem for thia Noah guy? All those smallish critters having population explosions?
...how could Noah get dinosaurs on the ark with him.
A far bigger problem is the 65,000,000 years between the last non-avian dinosaur and the first
Homo sapiens.
Juvenile animals of any kind are usually less aggressive, they are smaller, they eat less, which also means they crap less, and typically they tend to sleep more.
And many of them really need their mommies to survive, too.
"Hope I helped you think about it more."
