Età: quattro miliardi di anni

Fortey's perspective emphasizes the story of life itself, but I wonder how he decided which milestones to highlight in such a vast timeline.

The timeline spans billions of years, which makes it hard to grasp everything at once. Was that intentional to evoke awe, or did it make certain parts feel rushed?

There are so many fascinating developments in biology and geology—I'm curious how Fortey selected the ones that best tell the story of life's evolution.
