I don't get into the evolution debate, choosing to see evolution as both logical and flawed in principle. What i DO debate about is the condition/nature of the ancient Earth. I believe catastrophism drives any evolving traits more than incrementalism...and this goes into my belief that the Earthen gravity has increased considerably.

Consider the following:

www.usatoday.com...




How big? Bigger than you, and at 8 feet long as big as some Smart cars.

The discovery in 390-million-year-old rocks suggests that spiders, insects, crabs and similar creatures were far larger in the past than previously thought, said Simon Braddy, a University of Bristol paleontologist and one of the study's three authors.

"This is an amazing discovery," he said Tuesday.

"We have known for some time that the fossil record yields monster millipedes, super-sized scorpions, colossal cockroaches, and jumbo dragonflies. But we never realized until now just how big some of these ancient creepy-crawlies were," he said.



This would seem unsubstantial, unless you consider that the largest "bug" on earth right now is a japanese form of crab, weighing about 45lbs. There are two current lines of thought as to why this is the largest "bug" on earth right now:

1. the exoskeleton is unable to support the weight effectively becoming so thick in its effort to support the rest of the body, that little room is left for the softer biological parts. this seems logical, if over simplified.

2. The exoskeletons have several breathing holes and trachea's. As the shell becomes larger the trachea's become more narrow, inhibiting the aerobic functions of the organism.

Snce there is still no definitive answer, one would have to ask how this giant scorpion managed to be so large?

Initially, no...there was no predator capable of eating these animals. This is what paleontologists believe drove their extinction (fish with sharper teeth able to pierce the shell)....but i am not sure i buy that. I think extinction likely has been caused more by environmental factors moreso than predatory factors.

Regarding aquatic buoyancy....the largest "bugs" currently are a type of crab (described above) that live a semi aquatic life (as most crabs do). The buoyancy doesn't help them too much.

that is an interesting point. What effect would oxygen have on humans in greater amounts? would the aging effect be more pronounced due to the increased introduction of oxidizing elements?

What effect would it have on our atmosphere? One would expect that there would be a MUCH different atmospheric effect if there were more oxygen.

The daytime sky...what color would it be? With more oxygen/less nitrogen, what colors would we see?
