9. Superorganism: LARGE numbers of individuals living together in harmony, achieving a better life by dividing their workload and sharing the fruits of their labours. We call this blissful state utopia, and have been striving to achieve it for at least as long as recorded history. Alas, our efforts so far have been in vain. Evolution, however, has made a rather better job of it.
Take the Portuguese man-of-war. It may look like just another jellyfish blob floating on the high seas, but zoom in with a microscope and you see that what seemed like one tentacled individual is in fact a colony of single-celled organisms (). These "siphanophores" have got division of labour down to a fine art. Some are specialised for locomotion, some for feeding, some for distributing nutrients.
to some extent it drove the formation of the rest.
I teach high school bio and one day I said "from a biological standpoint, reproduction is what its all about." One of my cheekier students went home, came back the next day and she said "I told my dad that you said we're supposed to go out and have sex cause thats the whole point of life. He wants to talk to you..." I'll have to choose my words more carefully next time! (p.s. thankfully she was just kidding around!)
