Pre-Read notes
I adore natural history. Nothing makes me happier than learning something I didn't before about the imprint of life on Earth. This book, about prehistoric vegetation, seemed like the perfect choice for my interests! The first few pages already excite me!
Final Review
The tree that moves some to tears of joy is to others a green thing that stands in the way. —WILLIAM BLAKE p5
Review summary and recommendations
I loved the subject of this book and I learned so much about how plants support life, through the ages. I relished in Black's descriptions of different Earths of epochs past. Though I wanted more science, a deeper look at the species of interest, I had a lot of fun reading this.
I recommend this book to readers who love popular science, dinosaurs, or discussions of prehistoric Earth. A book that turned my very adult self into a kid for a couple of days!
Genetics alone are useless. DNA only makes sense in the context of its environment, an interplay between what genes can tell a body to do and whether that body is having its requirements met. p62
Reading Notes
Six things I loved:
1. What I mean by “when the Earth was green” is not some irretrievable past or a denial that, despite our efforts, there is a great deal of green around us today, but thinking of key moments that plants have changed the nature of nature itself just as we tend to pay special attention to the great springtime blooms when the first leaves unfurled all around us are so impossibly, vibrantly verdant that I can’t help but smile when I notice the hills around my home burst with color. p17 This gorgeous passage both displays Black's writing prowess and also defines the author's purpose for her text.
2. In a rapidly changing world, sex is one way to stay ahead of tomorrow’s changes. p27 When sex isn't sexy it's survival.
3. [T]he chromosomes split again into two parts to send out into the environment as spores. The plants don’t have control over where those spores land. If too many egg-producing plants land near each other, they might not get fertilized. If the spores land in dried-out patches of the beach, the liverworts won’t grow there. The fate of the spores depends almost entirely on wind and water, sand and sun, which then grow just to add more chance into the process. p35 It's wild to think about how much life depends on luck.
4. The story about the monkeys on the raft is one of the best things I've ever heard!
5. Plants can be surprisingly sensitive organisms. They’ve had to be. For a tree like the hackberry , rooted in one place for the entire duration of its life, there’s no way to physically evade hungry herbivores or forcefully shoo them away. In such circumstances, plants have had to evolve ways to both detect danger and, if not drive the attackers off, quickly repair the damage done from so many hungry mouths. p109 Plants are amazing. I love the approach Black chose, to discuss the plants and animals that have always interacted, needed each other, depended on each other.
6. How can I not love a lengthy description of ancient saber-tooth cats enjoying a wild patch of fresh catnip!?
One thing I didn't love:
This section isn't only for criticisms. It's merely for items that I felt something for other than "love" or some interpretation thereof.
1. It doesn't affect readability, or at least hasn't yet, but this author writes some very long sentences. They are well-built, just phrase-heavy. *edit The long sentences are part of this author's style, but she writes them well, and they are perfectly readable throughout the text.
