i see you read the whole article from the link? then you would have some understanding. genetics is used for the diversity of differences. the fact of the worm traces in an older period than the cambrian. the trails, although scarce, are proof of earlier existence than cambrian. the diversity was there before. you are only spinning and confusing yourself shag. a large fossil record is not proof that everything happened at once. it only proves a large diversity at a given time.
What? It seems you may not fully understand what you are posting. Everything I said was consistent with what was posted and wasn't spin, as you try to imply, and you know it.
The argument is that evidence suggest that there was more diversity then previously thought before the Cambrian Explosion, and that can explain the huge explosion of diversity in the Cambrian period because it really wasn't such a huge thing.
The problem is, the evidence still says nothing about evolution. All the evidence shows is adaptation, which it implies is evolution.
It is also based on questionable evidence. New, unproven techiques with questionable accuracy (new techniques based on "estimates"). The study also bases the info on fossilized dung where much of the genetic material is highly degraded, and a lot of admitted "trace evidence". All this (mixed with the fact that it is only one study) suggests that these findings aren't near as conclusive as you are trying to imply by posting it here.
It also makes some pretty big intellectual leaps and assumptions. Because we can find evidence of a more diverse population of worms in the pre-cambrian period then we originally thought, that shows that there was much more diversity across the board and that lessens the possibility that there was an "explosion" of diversity in the Cambrian period.
It also never shows anything that can be viewed as evidence of evolution, which is the whole point of this debate. Only adaptation is every shown (and questionably, at that).
Your whole point in posting that (that the Cambrian Explosion wasn't an "explosion" as there was already much more diversity they originally thought in the pre cambrian) is hardly conclusively proven. At best, a little doubt is cast on the Pre-Cabrian explosion by this study, but one study, no matter how accurate, cannot disprove something like the Cambrian Explosion (which this study really doesn't try to do, by its own admission). More studies and much more evidence is needed to logically disprove the Cambrian Explosion. The study really only suggests a reasonable diverse population of worms, likely in the pre-cambrian. The rest is mere speculation and inference based on assumptions and leaps in reasoning.
using new tools to probe old mysteries is what science is about. you seem to be rather stuck in age old answers that don't answer anything. just pose the mystery and leave it at that.
So new methods must not be questioned?! That's hardly logical. A new method of study (techniques, ect) has to be proven reliable before it can be view as having any credibility. It must be viewed as unreliable until proven otherwise. It's not like unproven and/or unreliable techniques haven't distorted findings before, leading to faulty or false conclusions, or been used before to intentionally spin the evidence and distort the issue (Computer models and global warming).
instead i prefer the new answers that narrow down the evidence rather than staying with ancient thought.(kind of like religion) keep hiding from new answers and you'll keep in your clouded ancient ways. and as long as you quote short, you can spin it how you like. take the whole section together, and it comes to a different understanding.
You prefer? So you are dictated by your own bias? You should not "prefer" any technique or answers over others. Otherwise you compromise your intellectual honesty in any search for the truth. You go where the info leads, not where you want it to lead; a uninterested search for the truth.
When it comes to old techniques vs new; old techniques are proven and consistent; giving a known degree of reliability that has been proven. New techniques don't have that, so logically must be viewed as unreliable until proven otherwise. If they are proven to be consistently more reliable then old techniques, then they eventually replace the old technique. When it comes to new vs old (in almost anything), the burden of proof always logically lies with the new, not the other way around, as you are trying to spin it. It's called the precautionary principle.
You are trying to spin logical, disinterested, critical thinking as "non-progressive" which is an ad homenem, underhanded rhetorical tactic.
Again, You need to make the argument easy to read to your audience. Break it down, summarize it in your own words, etc. If your audience can't understand the argument, then it is irrelevant, and suggests that you may not understand it and thus cannot break it down (which is becoming more and more likely in my mind).
