So I hear there is a hole in each pole of the earth by some guy whose in some weird religion or something. He says that there is a whole nother civilization under the earths crust. So I say "what like in the descent?" and he follows. "No, but how do you explain all the new species of fish we keep finding?" Well, lets see. We haven't discovered all of the species on land let alone the 70% water that makes up earth.

Anyone know what the hell he's talking about or if I can see these holes on google earth?

You would think that the salty runoff produced when the ice and snow melts would seep into the ground and kill the grass or kill fish in the river.

And what about all of the sand? It has to go somewhere too. Doesn't it clog storm drains?

This might sound stupid for some of you but ... some say that evolution is real and some otherwise ... anyways I'm wondering why did evolution stopped(if it ever existed) . I mean it did ... any difference between like 4000 years ago and now ? The only one i can see is techonologicaly improvement as well as increased knowledge amongst us. So I'm pretty sure that evolution does exists but I'm way to young and uninformed to confirm that.

With all of the exploring that human beings are doing, I would wonder what would happen if we found such a scenario. There are surely many planets that are "suitable." It's just a matter of finding one that offers the "exchange" that humans can tolerate.

We were shown a graph today in Biology, which showed the population of a certain type of Aphids throughout the 12 months of the year. The population increased greatly between the month of October and February. I was wondering why that happened at such a time, because where I live, the plants the Aphid feeds on have lost there leaves. I was unable to ask the teacher as the bell rang just then. My most reasonable guesses for this would be either this type of Aphid lives in the Southern Hemisphere, where October through February are the warmest months, or the Aphid thrives in cooler conditions, such as the moderate temperatures in, say, Florida. What are your ideas as to why this occurs?
