More homology for kids...

This is a passage from Jean Craighead George's children's book Julie, which is the sequel to Julie of the Wolves, my all-time favorite book from my grade school days.

"When Julie and Ellen were alone, Julie came down from the iglek and sat beside her.

Ellen," she said, "our next lesson is about how every beast and plant is dependent on every other beast and plant."

"I understand that," she said. "You have taught me well."

Julie despaired. She had been talking to Ellen since the sun had gone down about cycles and the rise of one animal and the fall of another. She had held up her hands and told her how the Eskimo knew they were related to all the animals because they all had the same bones in one shape or another. She had told her that wolves kept the environment healthy, and that when the environment is healthy, people are healthy.

And still Ellen had told her she would kill a wolf to save the oxen and Kapugen agreed with her.
