- Wedgwood Rock (Wikipedia)
Wedgwood Rock is a glacial erratic (known to geologists as the Wedgwood Erratic) near the neighborhood of Wedgwood in Seattle, Washington. Its mineral composition matches that of Mount Erie, on Fidalgo Island in Skagit County, Washington, 55 mi (89 km) north. Prior to the establishment of the Wedgwood neighborhood, the erratic was known first as Lone Rock and later simply as Big Rock. Transported to its site by the Puget Lobe of the Cordilleran Ice Sheet during the Vashon Glaciation more than 14,000 years ago, it was a landmark for Native Americans in what was once a dense forest.

- Meet the Eukaryote, the First Cell to Get Organized (quantamagazine.com)
Three billion years ago, life on Earth was simple. Single-celled organisms ruled, and there wasn’t much to them. They were what we now call prokaryotic cells, which include modern-day bacteria and archaea, essentially sacks of loose molecular parts. They swirled together in shallow, primordial brews or near deep-sea ocean vents, where they extracted energy from the environment and reproduced by dividing one cell into two daughter cells. Then, one day, that wilderness of simple cells cooked up something more complex: the ancestor of all plants, animals and fungi alive today, a cell type known to us as the eukaryote
