Trees Prove That Life Isn't Just about Survival of the Fittest
Trees are far from dumb; they talk and share, because they need each other to live better lives.
1. A lone tree does not live as long. That fact could shift views of how the whole tree of life works.
2. Trees are social, reveals Peter Wohlleben’s The Hidden Life of Trees, they “talk” and share.
7. So much for Richard Dawkins' claim that “there is no welfare state in nature.”
9. As microbiome research has shown “symbiosis isn’t rare. It’s the rule.” All natural animals and plants use collaboration.
10. The "red in tooth and claw" view of biology needs to be updated, says David G. Haskell in The Forest Unseen. Nature’s “economy has as many trade unions as robber barons.”
11. The idea that biology is dominated by individual genomes ruthlessly competing is turning out to be “pleasant fiction” (Ed Yong).
12. A gene’s survival “vehicle” (the genes that every selfish gene must cooperate with to survive) typically extends beyond its body. Those survival vehicles can include its herd, or in our “by nature self-deficient” case, our “teammates”.

Jonathan Zimmerman explains why teachers should invite, not censor, tough classroom debates.
- During times of war or national crisis in the U.S., school boards and officials are much more wary about allowing teachers and kids to say what they think.
- If our teachers avoid controversial questions in the classroom, kids won't get the experience they need to know how to engage with difficult questions and with criticism.
- Jonathan Zimmerman argues that controversial issues should be taught in schools as they naturally arise. Otherwise kids will learn from TV news what politics looks like – which is more often a rant than a healthy debate.
Controversial map names CEOs of 100 companies producing 71 percent of the world's greenhouse gas emissions.
- Just 100 companies produce 71 percent of the world's greenhouse gases.
- This map lists their names and locations, and their CEOs.
- The climate crisis may be too complex for these 100 people to solve, but naming and shaming them is a good start.
It marks another milestone in SpaceX's long-standing effort to make spaceflight cheaper.
