The vanilla orchid required an outside germinator to germinate. A very small bee is probably the only germinator in nature. The orchid is only open on 1 morning of the year. How did a system like that evolve? I'm thinking the orchids probably had an ancestor that was germinated by the bees, and it evolved into the vanilla orchid. What do you think?

Did you ever wonder if everyone sees the world completely differently than you? The colors that somebody else sees could be completely inverted from the hues that you normally associate with the word "blue", or "red". At some point in your life, somebody must have held up an object and said, "This is blue." etc. Do you think it is completely possible that everyone sees the world differently? Nobody has the same exact eyes when it comes to the amount/shape of cones, rods, etc., so wouldn't this make sense?
