Four billion years ago, our planet was water and barren rock.

Out of this, some mighty complicated chemistry bubbled up, perhaps in a pond or a deep ocean vent.

Eventually, that chemistry got wrapped in membranes, a primitive cell developed and life emerged from the ooze.

But how?

Among the many mysteries is a chicken-and-egg problem to solve.

Knowable Magazine | Annual ReviewsAt the dawn of life, did metabolism come first?Some scientists propose that in the beginning, geochemistry gave way to biochemistry — with no genetic material necessary. Only later did RNA and DNA appear.

Spring is in the air, so viral posts about male trees triggering allergies are once again in the algorithms and I must trot out this article: slate.com/technology/2021/10/b

For those who read headlines and do not click -- like all viral posts, the "facts" you are seeing are sketchy, at best, and grifting, according to some.

And instead of insidious "botanical sexism" for your sneezing fits you might want to consider the much more prosaic villain of.......

....climate change 😀

“It’s the last major shift that happens to our universe.”

A pivotal period — when all that hydrogen went from one form to another — is known as the epoch of reionization. It began with our cosmic dawn and ushered in the modern era with all its marvelous textures and features. It serves as the backdrop for when the universe grew up.

Everything changed over that billion years or so and nothing much has changed in the billions of years since.
