I’m reading a book about writing that features great selections from all kinds of different books. Here’s one from Rachel Carson’s The Sea Around Us:
When they went ashore the animals that took up a land life carried with them a part of the sea in their bodies, a heritage which they passed on to their children and which even today links each land animal with its origin in the ancient sea. Fish, amphibian, and reptile, warm-blooded bird and mammal – each of us carries in our veins a salty stream in which the elements sodium, potassium, and calcium are combined in almost the same proportions as sea water. This is our inheritance from the day, untold millions of years ago, when a remote ancestor, having progressed from the one-celled to the many-celled stage, first developed a circulatory system in which the fluid was merely the water of the sea.
I’m pretty much swooning out of my chair.
