In the continual struggle to hold onto and make sense of what I read, I have for years now typed up notes on the books I want to remember.
From yesterday's on Origin Story:
Luca is our "last universal common ancestor"— a hypothetical creature, sort of alive but not fully alive, a porous rock that lived at the edge of alkaline oceanic vents. From Luca (and there were many Lucas) all earthly life flows. But it took three billion years to move from Luca to the multicellular organisms that ultimately gave rise to big life.
Or this: the progress of evolution, much like the life of a soldier, consisted of long periods of boredom punctuated by moments of sheer terror. In this case, though, the terror came from mass extinctions, the greatest of which occurred 248 million years ago when 80 percent of all life vanished from the planet probably as the result of massive volcanic eruptions.
The older I get, the more I wish I'd learned when I was younger. But in the case of this book, I console myself with the knowledge that many of these facts weren't even discovered when I was younger!
