"It's 6 billion because we each have two genome copies. We knew that long before any of the genome was sequenced by anyone."
Now if only SCIENCE would have let the rest of us know.
"Sorry, but if an expert in the field can't figure out what you're talking about, it's vague. Were you talking about changes to individual organisms in a new environment (i.e. phenotypic plasticity)? Or about some kind of non-genetically (epigenetically?) inherited change in the new environment? Or about changes to gene regulation?"
So, you don't know what speciation is?
Don't know what gene regulation is?
Don't know what hereditary change is?
The only way my statements could have been viewed as "vague" is if the above terms were uncertain to you.
"I didn't address any valid point raised because you didn't raise any valid points. Yes, error correction in DNA replication (for example) is a real thing, and it reduces the mutation rate. It's also very well known to evolutionary biologists and in no way invalidates anything about evolution.................................
and in no way invalidates anything about evolution."
I suppose if one doesn't ponder the conundrum it wouldn't invalidate anything.
"You're talking here about the genome. The
genetic code is the set of rules for translating DNA into protein; it is embodied in 20 enzymes, and is not complex at all."
When you talk like this, I suspect genetics isn't your field of expertise.
"Whatever the human genome codes for, it is itself not particularly complex; it is a linear string of nucleotides, each of which can hold at most 2 bits of data. And that's it. It holds (very loosely speaking) a set of instructions for making some tens of thousands of proteins. Your computer is more complex than the genome. Your brain, which ultimately produced by the genome, is vastly more complex. Simple processes can generate systems more complex than the rules."
That is profoundly naive. I was going to write more, but what can be said.
"I'm getting the impression that you have not studied biology."
And I hold you haven't perceived what you have studied.
