Thought for the day: We cannot live for ourselves alone. Our lives are connected by a thousand invisible threads, and along these sympathetic fibers, our actions run as causes and return to us as results. [Herman Melville]
Are you familiar with the
butterfly effect? I took that picture on the left when we were at a butterfly festival, where a monarch butterfly took up residence on the top of my head for a good while. It was actually very cool, but the
effect that particular butterfly had on me after doing his itty bitty business on my head is... when we got home, I washed my hair.
But um,
that isn't a bona fide example of the butterfly effect. In essence, the actual effect, or principle, says that a tiny change within a complex system may have a huge effect. Originally, the phenomenon was ascribed largely to weather, in which American mathematician and meteorologist Edward Lorenz, who established the chaos theory, as well as theories regarding weather and climate predictability, offered the metaphorical example of how the specifics of a tornado's path could be influenced by something as minor as the flapping of a butterfly's wings.
It speaks to our larger expectation that the world should be comprehensible... that everything happens for a reason, and that we can pinpoint all those reasons, however small they may be. [Peter Dizikes, journalist]

Just to be different, I'm going to go in the opposite direction. Instead of moving from a tiny cause leading to a huge effect... I'm going the other way. I'm going to start with a
mastodon.
Can't get much bigger than that!
Would you believe that something these behemoths did back in prehistoric times contributed to the survival of a tiny butterfly still living in Georgia today?

The paw paw tree is fairly common here in Georgia. In the springtime, its flowers are quite lovely, but they, um... STINK. Literally. Kinda like dead fish or rotting meat. Matter of fact, the leaves and bark have the same distinctive stench.
But these trees also produce a fruit, as shown in this picture, and it's the largest edible fruit indigenous to the U.S. They range in color from a yellowish-green to brown, and their insides are creamy and similar in taste to banana custard. Or so I've been told. I've never eaten one.

But lots of animals devour them. But they only eat the sweet fleshy part.
See, the seeds range in size from 1/2 to 1 inch, which is too large for any living animal to swallow whole.
Not a problem for our ol' pal the mastodon.
Mastodons gobbled 'em up, seeds and all... and then they continued their meanderings around the state. What goes up must come down, and what went in had to come out.
Meaning, as these mastodons wandered around the state, they um,
sowed these undigested seeds wherever they went, and thus assured the spread of this species. The diet and excretion of these creatures from eleven thousand years ago directly led to the paw paw patches that are still seen around the state today. But how about that...
tiny effect I mentioned earlier?

Meet the zebra swallowtail. Yep, a butterfly.
The only thing its caterpillar will eat is the foliage from a paw paw tree. So, no mastodon poop containing paw paw seeds, possibly no paw paw trees today, and no zebra swallowtails.
One thing kinda interesting about these butterflies. The stink I mentioned from the trees? It comes from a chemical, a naturally-occurring insecticide called
acetogenins, and after eating the stinky foliage while in the caterpillar stage, the butterflies retain a trace amount of the substance for the rest of their lives, which provides an effective protection from predators, who evidently, don't like smelly food.
So, in essence, this lovely little butterfly, which we saw at the festival, owes its existence, in part, to the eating and pooping habits of a creature which lived in the very distant past.
Cool huh?
There is a deep interconnectedness of all life on earth, from the tiniest organism to the largest ecosystem, and absolutely each person. [Bryant McGill]
The moment you realize your bones are made from the same dust as the planets, your lungs breathing the air of migrating butterflies, and your blood is pumping because of the love and care of thousands is when you realize you're not as broken or alone as you think you are. You are full of the world. [source unknown]
Learn how to see. Realize that everything connects to everything else. [Leonardo da Vinci]
Cosmos is a Greek word for the order of the universe. It is, in a way, the opposite of chaos. It implies the deep interconnectedness of all things. It conveys awe for the intricate and subtle way in which the universe is put together. [Carl Sagan]
Another kind of paw paw flower...

Until next time, take care of yourselves. And each other.
Whew! Thanks for telling me. Snorkeling on the beach isn't nearly as much fun.
