Makin’ DNA was a cinch

If you want to know something about science, wouldn't you be better off trying to find an educational source for it? An internet forum is hardly the place to learn anything -- except what a lot of uninformed people think.
We can do better than that. From large rat like creature to human, 160 million years. And all it took was a mass extinction event about 65 million years ago.
Though I'm sure some humans still have the rat like tendencies.

What are you identifying as the starting point for the formation of DNA?
Single cell organism to land plant encompasses multiple significant steps, the timing of which wasn't exclusively due to the pace of biological evolution.
Why are you measuring from "mollusk" to humans? I'm not even sure they'd be directly on the same evolutionary branch.
I also don't trust you on the numbers either. You could really do with some references for these statements if you expect any kind of serious discussion. Of course, if you didn't want any kind of serious discussion do please let us know so nobody needs to waste any more time.
How accurate do you consider your estimates above are and what are you basing them on?
What are you basing your assertions about the origination of DNA on?
It seems to be rather spurious estimates to be basing much on. The comparisons are not even clear. Chemical evolution compared to the evolution of modern organisms. The environments are not known to be the same for the items you are comparing.

Twilight Hue
Twilight, not bright nor dark, good nor bad.
Amazing how the molecule works.
History of DNA - What is DNA & How Was It Discovered? | LunaDNA
The discovery of DNA was the genesis of being able to diagnose disease earlier & better assess disease susceptibility. Learn about the history of DNA here!

And to think it was discovered in 1869!
Optimistic frubal.
Nucleic acids, amino acids and lipids don't need particularly complex chemistry to form. These basic life components could easily have formed in an early Earth environment and assembled into self-replicating biotic structures.

Exploring the Emergence of RNA Nucleosides and Nucleotides on the Early Earth
Understanding how life began is one of the most fascinating problems to solve. By approaching this enigma from a chemistry perspective, the goal is to define what series of chemical reactions could lead to the synthesis of nucleotides, amino acids, lipids, and other cellular components from...
