The problem arises out of discussing "common descent" as that was understood for 150 years, and what it now means.

It's become quite complex and is no longer the simple, straightward mommy-daddy, huggy bear stuff it used to be.

That is, the discovery of science informed the language used.

My complaint has been with the continued use of the word, limited to its old meaning, in the current context.

The word "computer" used to mean someone who computed mathematical problems. The meaning changed.

OK, share with me why it no longer means sharing an ancestor with another species? Or could you describe a new more inclusive definition.
