“Why did God worry about saving animals on Noah’s ark and then after some years let many of them become extinct? Why did God want to save animals from the flood and not save them from extinction afterwards? If God knew many animals would go extinct, then why lose time to save them on the ark?”
What time was lost in saving animals on Noah’s Ark that God knew would go extinct after the Flood? There’s no indication that time was lost. As to why God allowed them to go extinct after the Flood, God didn’t change the way the world behaved after the Flood (Genesis 8:22). As such, survival on the Ark was no guarantee of survival after the Flood.
Yes, God blessed the animals coming off the Ark to be fruitful and multiply (Genesis 8:17), just as he blessed the animals in Genesis 1. But the environment had drastically changed because of the Flood; there was no guarantee it could support the same sort of biodiversity it supported before the Flood.
We have to remember that God designed the biogeography of the pre-Fall world (Order in the fossil record), and it would’ve developed in response to that. Not so with the post-Flood world. Animals migrated from a single point, and the immediate post-Flood conditions were very harsh. The world had just been flooded!
It’s not surprising that many animals would’ve found it too hard to cope with the new, much harsher conditions, and died out as a result. Competition for resources would’ve been quite intense, so the smaller, faster, and more environmentally adaptable would’ve had a distinct advantage. Smaller animals would’ve done well because they needed less resources. Faster animals would’ve done better because they could explore further for resources. And more environmentally adaptable animals would’ve done better.
I also suspect that organisms that regulate body temperature internally would’ve generally fared better than those that don’t. In other words, ‘warm blooded’ animals like mammals and birds would generally be more adaptable than ‘cold blooded’ animals like reptiles and (possibly) dinosaurs. Plus, the smaller versions of those would’ve also had a better chance of lasting longer: they would’ve been less competition with or obstruction to humans; they would’ve needed less resources; and the shorter generation times for smaller creatures would’ve made them more adaptable to new conditions in the long run.
In other words, mammals and birds were better equipped to handle the harsh conditions of the post-Flood world than dinosaurs and large marine reptiles, and smaller mammals and birds were more likely to outlast larger versions.
