[Gandalf_The_Gray]

Thought, and an ability for thoughtfulness, exists within humans and animals, and I'd call that ability ... spirit.

Question is ... Does spirit exist in all living things?

Yes...That's what makes "living things" alive!

Modern science is telling us some wondering things. One for-instance comes from Steves Jones' modern update of Darwin's book. ("Darwin's Ghost," pg 284) "

In there, Jones tells us: "About a thousand genes are shared by every organism, however simple or complicated. Although their common ancestor must have lived more than a billion years ago, their shared structure can still be glimpsed. It shows how the grand plan of life has been modified through the course of evolution."
