Hello Zoe... I really liked your comment and your use of the word "primal."
I ran across this factoid that seems to tie into your comment and word choice. The article talked about a facet of evolution I had never heard of... "evolutionary stasis."
A little more research taught me evolutionary stasis is "... a relative lack of evolutionary change over a long period during the history of a species."
Their example was the shocker in what I was reading. They said,
"The fern Osmunda claytoniana [Interrupted Fern] is a paramount example of evolutionary stasis; paleontological evidence indicates it has remained unchanged, even at the level of fossilized nuclei and chromosomes, for at least 180 million years."
I realize this is not earth shattering news... and I'll never see it mentioned by David Muir. I also realize factoids like this sometimes bore the ___________ out of some people.
I decided to share it anyway.
Staying absolutely the same... down to the nuclear level... for 180 million years. Now that is a mind boggling fact... especially in light of beliefs like, "Nothing stays the same."
Apparently some things do.
