Trees are essentially growing chairs. There are lots of primates that sit and sleep in them.

Our ancestors didn't need any genetic enhancements to be able to sit for twelve hours a day and eat fatty, sugary foods, but we need enhancements that handle that altered environment.

You can't just hoard your ideas inside the ivory tower. You have to get them out into the world.

Clearly, we are a species that is well connected to other species. Whether or not we evolve from them, we are certainly very closely related to them. A series of mutations could change us into all kinds of intermediate species. Whether or not those intermediate species are provably in the past, they could easily be in our future.

“Plant trees for others, whose shade you will never sit under.” ~ Tom Baker

They looked as if they had trees growing out of them.
