2ek4tl | How do animals, like the chameleon "see" the world with eyes that move independently from each other? | Do they see two images or switch between the two? The whole idea can seem really foreign and hard for me to understand since I've only seen the world one way with eyes that are both front facing. That brings up another similar question, what about animals that have eyes on either side of their head? | askscience | http://www.reddit.com/r/askscience/comments/2ek4tl/how_do_animals_like_the_chameleon_see_the_world/ | {

21ib0a | How did America make the transition from a primarily tea-drinking nation to a coffee-drinking one? | I guess I'm asking why coffee grew in popularity as the hot beverage of choice and over what time frame this occurred. This didn't seem to happen in Europe, so I'm thinking it had something to do with the difficulty of importing tea after America gained independence. | AskHistorians | http://www.reddit.com/r/AskHistorians/comments/21ib0a/how_did_america_make_the_transition_from_a/ | {
