From all the kids with peanut allergies. And if you believe small birds are now the ancestors of large dinosaurs, then that would only be a "feather" in my cap (though I do not believe this). I believe dinosaurs died off as a result of the FLOOD and left their images in mud made up from debris of a complete ecological/geological system that was destroyed and reshaped by GOD over the course of a year and then progressed to this very day. The birds flew around and were among the very last to die. Their bodies/ bones are fragile were consumed and that is why no birds are found.
Whatever your point about peanut allergies is...?
Birds would not be "ancestors" of dinosaurs. The relationship between birds and reptiles is so obvious that a person has to be deliberately blind not to see it. Transitional forms with long tails, teeth, feathers, and a weakly constructed skeleton compared to modern burds...? Flightless dinos with feathers? You are welcome not to believe it but then maybe you wont believe it if you see a five dollar bill on the gorund.
Of course isnt really a topic, large / small, some modern birds are bigger than some dinosaurs were.
In any case, success in a biological sense is based on reproductive success, how many of a critter there are. Simple. Size has nothing to do with "degeneration"....did you think it does?
As for dinos etc dying off in a flood...really....that is a made up answer based on a lack of data.
There is absolutely no physical evidence for a world wide flood. Period! There just isnt. It would have left evidence but there is none. How would you account for that?
Another thing that canntt be accounted for in anything even vaguely resembling a reasonable way is that there never is found anywhere an assemblage of fossils fsrom different geological eras. If they all lived at the same time, this would happen at least once, somewhere. There is that taht church group has been digging for so long down in Texas trying to find human footprints with dino tracks. Sometimes there will be a fake carved, but nobody ever finds anything real. There is a reason for that.
No really, a world wide flood is a good story, but it makes no sense, ahd there is nothing but the pages of an old book to back it. Some of the ancient cities described can be found; but not evidence of a world wide flood.
Oh... what do you mean, "no birds found"? Paleo labs have lots of bird fossils.
