- gdo01, on 07/21/2009, -0/+6Oxygen levels.
"Checking the reptiles' breathing and metabolic rates, it was clear that the animals in the high oxygen atmosphere were breathing much less than the normal and low oxygen animals, probably because animals in the 30% oxygen atmosphere breathe in more oxygen per lungful, translating into a significant energy saving, which the reptiles could invest in growth."

- Richandler, on 07/21/2009, -0/+5I'm pretty sure it means bigger bugs though. Like giant spiders, scorpions and such.
- inactive, on 07/21/2009, -0/+5I think that only occurs with a higher oxygen content. It was around %30 back then.
- billraydrums, on 07/21/2009, -0/+3That's all we need. More little ***** yappy dogs.
- Hillsfar, on 07/21/2009, -0/+3They're called Cornish game hens.
- Animan351, on 07/21/2009, -0/+2Animals and insects used to be larger back when the O2 in the air was at a higher concentration.
That brings up something I've wanted to try for a while. O2 in the air is generally about 20.9%.Insects used to be way bigger when the earth had a higher O2, so if I were to make a terrarium with a few beetles or some ***** in it for a generation or two at around 35% O2 will I end up with some badass sized beetles? - Joe_rigby, on 07/21/2009, -1/+3I wish there was a way to make dragonflies huge again
- feomatteo88, on 07/21/2009, -2/+4i swear if chihuahuas get any smaller im going to go on a chihuahua-kicking rampage.
- TobiasParker, on 07/21/2009, -0/+2"Life will find a way" - Ian Malcolm
- atomheartmother, on 07/21/2009, -0/+2Oh yeah.
- skit4king, on 07/21/2009, -0/+2As long as we stay big and macho, it is not going to be a problem.
- TobiasParker, on 07/21/2009, -0/+2over several hundred generations, you probably would, then again, maybe there are issues we don't know about. I am actually surprised no one has tried this before.
- atomheartmother, on 07/21/2009, -0/+2I envision a world full of tiny roasted chickens.
- Animan351, on 07/21/2009, -0/+1Me too. That's why I've considered doing it. I'm inclined to believe it would take possibly only one generation before results may be seen.It's my understanding that for bugs like the male rhinoceros beetle they are genetically set to get large (largest, best fighter gets the girl) and that their current size is only limited by the space allotted to their lungs.
- Slackdragon, on 07/21/2009, -0/+1Then Corinish Hens will be called bees.
- cambob76, on 07/21/2009, -0/+1Did you or didn't you?
- SaladCactusKing, on 07/21/2009, -1/+2Can I get a pocket tiger?
- TheMachine1, on 07/21/2009, -0/+1Except for people we keep getting fatter is there a connection?
- ArchetypeRyan, on 07/21/2009, -3/+4What about the dinosaurs? The Earth was warmer during their era, but they weren't exactly small compared to the creatures of today. It's too bad the article never mentions them.
- Hillsfar, on 07/21/2009, -0/+1It does seem like animals can be bigger when there's more bio-diversity and food abundance.
Gosh it'd be interesting to be farming brontosauruses for burgers... - gdo01, on 07/21/2009, -0/+1When dinosaurs APPEARED. Dinosaurs were originally quite small ( http://en.wikipedia.org/wiki/Eoraptor ). The adaptation that allowed them to thrive during these low oxygen times allowed them to grow and differentiate when oxygen levels rose.
- whatthefu, on 07/21/2009, -0/+1That would be just our luck.
- ArchetypeRyan, on 07/21/2009, -1/+2.... you quoted the wrong part of your own article. The opening paragraph states:
"... the dinosaurs appeared around the time when oxygen levels were at their lowest at 12%" So, by your own thinking, the dinosaurs STILL should have been smaller. I'm not saying this article (the one you sited or the OP) is wrong, I just think there's a gaping question that they left unaddressed: during one of the Earth's geologically warm periods, some of the largest creatures ever to roam the Earth were walking around. How can a theory that claims "warmer = smaller" explain this fact away? - InGenUse, on 07/21/2009, -0/+1Aww, too bad they're not getting bigger and mutating at a great speed. It'd be like pokemon :(
- leif777, on 07/21/2009, -0/+1Pff.. house hippos have been around forever: http://www.youtube.com/watch?v=NBfi8OEz0rA
- Darkshine, on 07/21/2009, -0/+1Last time the earth was warm I remember there being dinosaurs...
- secrity, on 07/21/2009, -0/+1I want a pocket Gay to help me select clothes and furniture. Yeah, I know, I'm gay, but I have no fashion sense. People look at me funny when I go to a high end restaurant wearing 501's, wife beater, harness boots, and a leather vest. I have a suit, but that is only for job interviews and weddings.
- Hillsfar, on 07/21/2009, -0/+1I think it'd be juicier, like turkey or ostrich.
But still. Imagine living the Fred Flintstone life... Bronto-burgers!!! - Spoomeister, on 07/21/2009, -2/+2It would, if there were such a thing as global warming.
- Inferny, on 07/21/2009, -2/+2This just means I will have to eat more of them :D
- artwhite, on 07/21/2009, -4/+4I may buried this as pseudo-science crap
- gusyehia, on 07/21/2009, -1/+1Smaller ant ? lolz
- Skankingmike, on 07/21/2009, -0/+0I would imagine brontosauruses would be more of a white meat, like birds.
- Obsession88, on 07/21/2009, -3/+3Smaller, tastier animals?
- dualaudi, on 07/21/2009, -2/+1makes no sense.. why are Africans so much bigger..
I mean, you know... not that i'm comparing or anything. - Eurynom0s, on 07/21/2009, -2/+1Am I really supposed to think it's a bad thing that the grizzly bears trying to eat me will be smaller?
- inactive, on 07/21/2009, -2/+1Finally! a scientific reason to explain my pe#is size on girl!!
- mwveasey, on 07/21/2009, -2/+1Yay! More furry things to stuff into my bunghole!
- Catspaw, on 07/21/2009, -2/+1Those in power probably are hoping are brains are getting smaller so we fall for this bunkum. I must need some more fluoride and mercury because I don't buy it.
- Exedous, on 07/21/2009, -2/+1LMFAO with all this global warming bogus. It's actually getting colder then it is hotter. C02 levels were much higher millions of years ago then they are today.
- Skankingmike, on 07/21/2009, -2/+0I think a better hypothesis would be that the world yo-yo's back and forth with size. I mean life arguably started out tiny microbes that over billions of years evolved into it's largest Dinosaurs. We've slowly been getting smaller since that era. So maybe the world is going back to original form? I mean they claim everything goes full circle...
- Presbyterian, on 07/21/2009, -7/+4Where do they come up with this crap.
