I miss our timeline.
I haven't mentioned it lately, so hardly any of you will even know what I'm talking about.
Those of us that reside in this house are scientists. Mostly our varied interests fall into the natural sciences category.
We are fascinated with evolution*.
Little Son perhaps began our investigations at the ripe old age of two, when he became first interested in dinosaurs. Somewhere around age five, probably, it extended to the environs. Volcanoes, fossils, asteroids....
No doubt he comes by it naturally, his Daddy is interested in all things geographic and biologic, and his Mama is a lover of the Earth, so....
And naturally we started going even deeper, into evolution. What a fascinating business that is. Seeing plants come to life, the earth's atmosphere changing over time...
We find so much satisfaction in learning about our world this way.
So. Our timeline.
We don't have a fold out piece of paper on our wall. Our timeline is the wall.
It's filled with things like
13.7 bya Big Bang: The Universe begins
4.567 bya Hadeon Eon Begins: The Sun and the Milky Way form
4.533 Earth and Theia collide
4.1 The surface of the earth cools enough to solidify. The atmosphere and oceans form.
4 bya Earliest life appears: Natural selection favors those molecules which are efficient at replication. DNA then takes over.
3.9-3.8 bya Archeon Eon: Organic life forms out of inorganic compounds
3 bya Oxygen is produced by Photosynthesizing Cyanobacteria
2.5 First organisms to utilize oxygen.
900 mya: The choanoflagellates develop. These protists are considered the ancestors of the entire animal kingdom.
750-580 mya Precambrian Varangian Ice Age: So severe that oceans freeze except in tropics. Last big freeze, after this, evolution accelerates.
475 mya The first primitive Plants move onto land - having evolved from green algae living along the edges of lakes. Accompanied by fungi, likely plants and fungi work symbiotically. Lichens exemplify this.
450 mya: Arthropods are the first animals to move onto land (exoskeleton prevents water loss). Among the first are millipedes and centipedes later followed by spiders and scorpions. Over the next 10 million years the Ordovician-Silurian extinction, constituting the second mass extinction.
Fascinating business, no?
Our work in progress has been a designated area all around the perimeters of our basement (not into the rooms, just the walls down and up the stairs and in the hallway). Which isn't a huge area, but it still makes for a pretty dang long line.
Plenty of room for Egyptians, Romans, Vikings, Babylonains, Sumerians, Mesopotamians, Leaders, Events, and personal favorites.
Back to the point.
Maddie took the Sharpie to it.
So all work came to a screeching halt several months ago.
To paint, or not to paint? That is the question.
We're eager to work on it again. We're eager to search out pictures of different periods, print them, and hang them accordingly on our walls.
We're eager to place sharks before the dinosaurs. We're eager for pictures of first mammals (the poor homely giant-rat-looking things she tut-tuts in a sympathetic voice).
We're eager for The Wheel, Fire, automobiles, and Space Travel.
And I've decided.
and we're starting over.
* We also believe in a God that is Everything (Absolute, if you will), and don't understand why The All couldn't have been the source behind evolution. For the record.
