"Well, a billion years ago - yes. All of us share the same most basic biochemistry."

You know, there is tendency among some to throw the term "billions of years ago" around like a Circus Clown might throw candle pins.

Biology, microbial and else, has not fundamentally changed in the last few billions of years.

You all ought to see yourselves, from a perspective that does not require you to be prone and facing the place commonly known as Mecca, or perhaps elsewhere! Ultimately, it is all the same thing. A rose by any other name is still a rose.

Well, call me a reactionary, and I'll call you what you truly are. Supporters of a faith with no real evidence to support it.

"Biology, microbial and else, has not fundamentally changed in the last few billions of years."
It did, by proceeding hierarchically in time. The number of aminoacids got fixed early. The same anticholinesteratics which work on cockroach, will work on you [as nerve gases]. Once choline/acetilcholine nerve transmission appeared [in multicellular organisms with nervous systems], it persisted ever since throughout. Once the basic land animal body plan with four limbs and one head appeared - ditto.
