[QUOTE="Tomb Spider, post: 221558, member: 39782"] Hypothetical Questions! I just want to talk about that, without any intention to apply any gained knowledge about it, so feel free to speculate and talk. 1. More Oxygen = bigger size? Would spiders grow to giant sizes if one artificially increases the amount of oxygen in the air? I guess same as insects etc. were much bigger when there was more oxygen in the air in early times (up to 30% vs 21% now). 2. Crossbreeds. Analogous to hybrids in plants and selection, would it be possible to breed giant tarantulas? Sure crossbreeds are something to avoid. I'm just curious. [/QUOTE]
