Where is every one? Why haven't we been visited by alien races, made contact with aliens, or even discovered a hint of an alien race? Ever since Fermi asked this simple question, people have been coming up with answers as to why we don't see aliens. Some solutions are scary, but I think a potential answer could be found by looking at our own solar system.

The more I learn about plants, the more I'm amazed. From insects to fungus and bacteria, plants form many relationships. Some plants even talk to each other through the air or underground, while others form three-way relationships with ants and fungus.

After a few memes with cats sitting on biology books making references to biology being soft and textbooks calling chemistry the central science, I figured it's time to start calling biology the Apex Science, or the apex of science.
