The largest of the prehistoric insects (with wing-spans up to 3 feet across) ... are still much smaller than what we see in SF features like "Them" ...
Your post that I was responding to, didn't talk about insects. It talked about "Everything in nature" and "Large scale changes in the size of living organisms".Dino's were made differently than insects ...
There you go, assuming that everything has always been the same.........You aren't aware that insects used to be HUGE?
I'm talking flies the size of a human head and centipedes measuring 3 meters in length.
Then there's also dino's and stuff.
Kind of naive to think it's "impossible", while we have the evidence that demonstrates the exact opposite.

Flying things got quite large at one time.True. I can't imagine the wingspan an insect the size of a schoolbus would need in order to fly. And how much muscle power in its legs or wings would it take just to get off the ground?
I saw that movie too. One night I was walking and some sprinklers automatically went off at a park and sounded just like “Them”.
In the epilogue of Antman And The Wasp, they were watching Them.When I was growing up, I saw the movie Them! which scared the Y2K right out of me.
I've heard that ants can't really grow that large because of some law about the square of the size means the less liklihood of survival.
Or something like that.
Would someone enlighten me please on this law?
Thanks!
Brontosaurus etc would have had leg bones commensurate with their size.
The point is you cannot just scale up an animal regardless - their bones would have to resize disproportionately to support the weight.
E.g. scaling a human by a factor of 10 would increase their weight a thousandfold but their leg bone bearing capacity only a hundredfold, so they would likely break their leg with their first step.
But supposedly oxygen content was also greater..... Scale a dragonfly up by a factor of 10 and you are still short of those that used to live with a wingspan of 2.5 feet. So do we now scale oxygen content up by another 40% which doesn't match our estimates?Insect oxygen delivery is via a network of dead end tracheal tubes which get increasingly inefficient with large body size, mostly due to supply to the legs. As detailed in this easy to read piece:

hard to imagine something the size of a giraffe flying too.... at least in today's current conditions.... but then I am not assuming everything has always been the same.....
Dinosaurs died out because their bodies became too big relative to brain size.
Dinosaurs died out because their bodies became too big relative to brain size.
"One hundred million years ago the reptilian age was drawing to a close. The dinosaurs, for all their enormous mass, were all but brainless animals, lacking the intelligence to provide sufficient food to nourish such enormous bodies. And so did these sluggish land reptiles perish in ever-increasing numbers. Henceforth, evolution will follow the growth of brains, not physical bulk, and the development of brains will characterize each succeeding epoch of animal evolution and planetary progress." UB 1955
That's the year Mad switched from a comic book format to a magazine format.1955? Really?

The ant is mentioned in Scripture, coexisting with mankind.Not... not what I was commenting on nor is it something I care about.
