my bad with the typo.
I think you are putting too much stock in your chosen dictionary.
Hmm, so now it's issue with the dictionary? Unless you want to link me to one, I'll likely go with that one since a lot of these key words get tossed into the mix and don't get defined. IMO, that is bad writing.
Descent is a parent/offspring relationship. Which is why a sculpture is not a descendant of the same rock it came from.
Alright, I can (reluctantly) go with definition that Descent = parent/offspring relationship. Reluctant because not finding that definition with online dictionaries either, and reluctant cause material didn't bring it up. But since I think your intent is to help clarify, I'm willing to say with original definition of Evolution that it means: parent to offspring relationship with modification. Even that doesn't ring in way I (and perhaps others) would like, but is best we have so far, yes?
No, a block of stone is still the same block of stone. Descent requires reproduction.
Yeah, I thought so. Was pretty sure this would come back to folk definition from other material. Really we're just talking about modifications through reproduction. That seems like most simple version that I can come up with.
When a child is born it isn't simply the parent being modified.... you have a new independent organism. When you make a sculpture you don't get a new object in addition to the original block of stone.
Seriously, let's not even debate the block of stone thing because the way you are stating it, is arguable. If we add in reproduction as key word to defining (biological) evolution, I think we can move on.
it's implied in the use of the word descent. You can't have descent without a resulting descendant.
Again, the reason why the sculpture analogy fails.
Again, I disagree with this logic, unless reproduction is brought into the fold. So, again, just assume I've accepted reproduction and we can move on.
It is weird that this wouldn't be brought up on that page since it is quite obvious a key concept, but I'll really do my best to give that literature benefit of huge doubts I have so far.
No it was adding nuance to the concept. It's still descent but now you know what is being modified... genes that are inherited from the parent(s).
The what is absolutely huge, and for you to minimize this in way you have thus far is not boding well for early part of this discussion. The definition without the what, and without the reproduction concept leave a heckuvalot open to other interpretations. At least from those of us thinking critically. Here are the original statements that speak to definition:
1. Biological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution and large-scale evolution.
2. Biological evolution is not simply a matter of change over time. Biological involves descent through genetic inheritance.
This is me adjusting what is being said, and I would say be somewhat generous to how it was conveyed in the material. If left the other way, it leaves lot in domain of assumption. I mean idea of "encompassing small and large scale evolution" is a vast assumption at this stage of the game. I include because if left out, I can see someone reading this thinking I left out a critical part (given how TOE actually 'works').
Descent with modification we are now saying equals reproduction with modification (in descendants). The second part is not saying modification of genes. It is saying genes are inherited, and I would assume (you might say imply) that gene modification is occurring. Without genes in the picture, I would say biological evolution (as theory) completely, or near completely, falls apart. So, genes is huge. I still think inheritance is not needed and/or is circular logic.
Since I'm apparently the only one thinking critically on these matters, I'll walk through why (again) I see it as circular:
genetic = relating to genes
genes = a unit of
heredity that is transferred from a parent to offspring
heredity = the passing on of physical or mental characteristics
genetically
Perhaps the way to get around the circular logic I'm observing is to not have part of genes definition that says "transferred from parent to offspring." And that's only a maybe (for me). The way I see the original statement making equal, possibly better, sense is by asserting: Biological evolution involves descent through genetics.
If I say the sky is blue... then say the sky is bright blue am I really changing things significantly. The sky remains blue, but now you have a more nuanced view of it.
THAT would be nuance. Using your analogy, and with what is conveyed in this definition / explanation would be saying, "the sky is simply blue and vast." Coupled with "Blue sky occurs through atmospheric conditions."
Now, I went with something that I assume is at least a little acceptable by the reader. But if I said, "Blue sky occurs through physical agents who paint that region of space," something like that, a vast assumption, is clearly adding more. Well, so is "atmospheric conditions." And so is "genetics" adding something most significant to concept of "modification." So significant, that I'm around 99% certain that without this add-on, TOE is DOA.
A gene is a basic unit of measuring DNA.
Genes are passed down from parent(s) to offspring. You inherit your genes from your parents.
wa:do
Really? You want to go with Gene = basic unit of measuring DNA. I consulted 3 sources and none say that. That connotation also is opening up whole other aspect that I'm sure gets addressed, but is not so much conveying meaning, as much as (possibly) distinguishing specialization of terminology. Aka, is jargon.
Your definition of genes gets away from circular logic, but I am somewhat challenging that understanding of the term. If you want to go with that, instead of hereditary unit, then let us be clear from this point on. Hopefully goal posts don't change down the road.
