Hi,

I have read so many articles about plants being emotional and conscious.
But they don't have a nervous system or a brain.
How can this be?

PLEASE DO NOT ANSWER WITH LINKS.

Thanks

Do you think it's possible that after about, say, a few million more years of evolution a brain could develop telekinetic ability? Are there any legitimate scientific reasons to believe this could happen?

I'm asking because I'm trying to write a science fiction story. But I don't want my story to be completely absurd. I want it to be at least somewhat plausible.

Lets say Humans all of a sudden left Earth and now we live in other Star Systems. What do you think the next intelligent species would be? I would say Octopus, Squid, or even an Ape.

Does any one know the dbSNP identifier (i.e. the rs number) for the Factor V Leiden mutation? I know it's commonly reffered to as G1691A, but I'm trying to be precise and the best way to do that is to use an rs#. I find it really hard to believe that it's not annotated in the database.
