Has anyone ever done, or heard of anyone doing research on arachnids or insects, in an oxygen enriched environment? Supposedly the lower oxygen levels in todays environment is why they don't attain a larger size, as they were in prehistoric times.

Ive never heard of any actual research but I have heard some interesting theories, more Biblically related, on why animals were able to grow bigger, and why pterodactyls were able to fly then and not now. But they are all just theories.

Insects grew larger due to higher oxygen concentrations, that is definitely true. Their gas exchange depends upon a favorable concentration gradient and with higher O2 in the atmosphere, the concentration would support much larger organisms. I have never heard of anyone experimenting on this, but honestly I have never looked into that idea either.

Just fair warning.
We will not be debating anything about the bible at this site.
Let's move on.
Thanks.

I think it was an episode on the "Evolve" series from the History Channel where they showed a person doing experiments with insects in O2-enriched environments. It was probably the episode called "Size." The "Venom" episode features our own Dr. Bryan Fry. Great series and I've shown several episodes to my students. They need a better understanding of evolutionary biology anyway.
