Yes, plants tend to handle genetic duplication and even cloning rather well. But are plants really alive in the same sense as humans are alive? But that's a question for another day....
Well, yes, they are, for the purposes of our discussion here. They have genomes, they have chromosomes, they reproduce sexually, and they must express their genes - and the mechanism by which they do so is, for all intents and purposes, virtually identical to the way we do it.

Let's not move the goalposts please. In general, we were/are speaking of two chromosomes fusing and or one or more chromosomes duplicating within the same kinds of animals or during macro-evolution over a period of time.
Nobody's moving the goalposts. I'm not sure that phrase means what you think it means. However, we ARE probably digressing from our primary topic of conversation, sure.
Old Timer said:
The fusion of chromosomes in other animals/mammals similar to that found on human chromosome #2. (Like with sheep, which have three such chromosomes. Rats (or mice?) too, but I forget the number of fused ones they actually have.
Fair enough. I was worried that you were trying to imply that the actual
genetic sequence(s) were somehow similar or the same.
Old Timer said:
So I guess you are intimating that "the split" was "so deep in time" that we wouldn't find any record of it in either the chimps or the sheep today. Is this what you mean?
No, we certainly would, but the split is deep enough to necessitate comparisons with other species in order to be able to track these changes with any level of confidence. And looking to chromosomal fusions/duplications as evidence of common ancestry probably wouldn't be a very good approach, in this particular case.
Time and context both matter a great deal here.
Old Timer said:
I treat it as markedly equivalent when trying to find or sort out a logical scientific reason for the belief that two chimp chromosomes (now they say not from chimp #2 and an unknown one, but from chimp #13 & #14 if I'm not mistaken) fused to create a single chromosome in humans. "Evolutionary Science" makes the claim we find a record of the fusion of two chimp chromosomes within the human chromosome #2. I admit it is quite a leap, and I personally believe it is base more so on a presuppositional belief system or thinking rather than utilizing good scientific deduction.
You see, before Science even knew that chromosomes existed, it was already postulated by certain atheists that humankind evolved from chimps/apes. You do not walk through the doors of the lab with this kind of mindset (or presupposition) if you want to experience true Science or true, properly disciplined and vetted scientific endeavors. So knowing, if a scientist did not or does not set aside his or her presuppositional beliefs prior to genetic researchers finding a fused human chromosome (#2), one might make the leap that this explained at least why chimps have 48 and humans only have 46 chromosomes even though one evolved from the other. Don't you agree?
Question: Has the long standing (100 + years) atheistic belief that man evolved from chimps/apes skewed recent "scientific" conclusions made by some geneticists? (Rhetorical, but you and I both know the answer based on the now debunked claims made early on within genetic research.)
You keep conflating evolutionary theory with atheism. It is not a necessarily atheistic belief. I happen to know more than a couple of scientists who happen to be Christian and also acknowledge evolution as fact.
But getting to your point, the only time that such presuppositions are truly detrimental, in a scientific context, is when they lead to poor study design or result in data that are not representative of reality. That is simply not the case here. The data are what they are - and while the authors of a study may come to their own conclusions about the implications of those data, they don't
force anyone else into those conclusions.
EDIT: Actually, The End put it very well when he said the following:
The End said:
In this context, its a prediction - they'd predict that they'd find a link between humans and chimps, based on the theory of evolution which is supported by over a hundred years of work across multiple disciplines. Predictions are part of how science works and part of its power to explain.
The work on human chromosome 2 is published for any geneticist that wants to see it and repeat the tests. If the work is in some way flawed, anyone that is qualified is welcome to repeat the work and show how it is flawed.
And, again, it is silly to look at this particular piece of evidence in a vacuum. You seem to insist upon this mindset, for reasons I still can't comprehend. Scientists don't simply ignore previous evidence. It appears as though you are advocating that they should.
All of this begs the question: do you know what hypotheses are, and how they are formed? Do you understand their practical utility in terms of the scientific method?
Also: how would
you explain or interpret these findings (regarding human chromosome #2), in a scientific context? If it should be ignored as nonsense, then the burden is on you to explain why.
Old Timer said:
Forgive me, but you don't need to keep calling in semantics in order to mask the obvious points I am making. Personally, I call a spade a spade, so in prose this means a careful choosing of the vocabulary utilized.
Here:
Devolution (Plz see #2)
Just because the word exists doesn't mean it reflects any sort of biological reality. Also, that is an
incredibly vague definition.
Old Timer said:
1. & 1.1 - Because the researchers say it themselves. Well, at least the ones that value candor say it.
Really? Do you have a source for this? Forgive me, but I do suspect that you're fabricating this claim.
Old Timer said:
They believe that the initial individual to undergo this "evolution" would have to have reduced its number of chromosomes to 47 in the first few dozen, hundreds, thousands or whatever number of the early generations. You and I know that a human with 47 chromosomes, arising from duplication, suffers debilitating physical and mental affects. We also both know that a reduction in the number of chromosomes would be a fatal, species ending event were it to occur, which includes a reduction occurring in humans and or chimps "deep in time."
SO IT IS BELIEVED, BUT IT IS NOT KNOWN, THAT SOMEHOW EITHER A FERTILE OFFSPRING WITH 47 CHROMOSOMES SOMEHOW SURVIVED LOSING A CHROMOSOME, or that somehow chimps/apes are actually the descendants of humans/humanoids and the chimps/apes were somehow able acquire another chromosome pair in the evolutionary past.
*Sigh*
Why are you ignoring my earlier point about the fusion of the two chromosomes leading to no loss of genetic information? I even explained in detail how and why this was the case.
Yes, chromosome number was reduced, but there was no
deletion. How are you
still missing this crucial point?
If there was no deletion of genetic information, why would such an event prove "detrimental?"
Old Timer said:
One slight problem with the latter choice though. You see, it was already asserted by atheists that man evolved from the chimps/apes, so the alternative choice of chimps/apes evolving from humans is not really a viable alternative after all. Although its not being viable isn't based on genetic research per se, it is based on over a hundred years worth of presupposition of the atheists. (They can't change the story now.....)
Actually, humans didn't evolve from modern apes, nor did modern apes evolve from humans. So I'm not quite sure what it is you're trying to say here...?
^ You do understand this relatively basic concept in human evolution, correct? That nobody asserts that humans evolved from modern apes (including chimps)? If you don't, you may want to reconsider your position, as it is based on a severely flawed understanding of evolutionary theory.
Old Timer said:
Did the change in chromosome number two occur first in the human male or human female? I believe it's a valid and important point. If you honestly think it isn't, I drop it for the sake of brevity and move on.
1) It probably didn't occur in humans.
2) Why would it matter, exactly? I'm curious.
Old Timer said:
You asked about my experience. I am am autodidact and to date have researched evolutionary "Science," from both sides of the fence if you will, for over 35 years. (Oh, usually only a autodidact knows what the word means without googling it. )
I know what it means. It's also a giant red flag when somebody proclaims themselves to be an autodidact.
Old Timer said:
C'mon Dr Evo, you know hose these types of discussions can get way off track and follow rabbit trails so to speak. I'm not being disingenuous in the slightest as it is the only evidence we are currently speaking about.
As much as you might want it to, it doesn't exist in a vacuum, Old Timer.
If your aim is to ignore any semblance of context, then I'm not sure this is a conversation worth having.
Old Timer said:
No I was not aware of your profession exactly, but I'm sure you'll agree that the Dr Evo screen name is a telling nom de' plume nonetheless.
I wasn't trying to be subtle.
Old Timer said:
Okay, I will agree to disagree as for my money, losing information is not evolving in the sense of survival of the fittest or mutations over time.
Given the trend observed in parasitic organisms, and given the prevalence of parasitism, I'm going to have to conclude that you're sorely mistaken here.
Also, the loss of information IS a mutation.
You call it semantics, I call it precision.
Old Timer said:
One point of order first if I may, my faith and trust are solely derived from the Words in the Bible and not from "my religion."
Which is odd, coming from someone who claims to have such a high standard for evidence.
Old Timer said:
In my 35 year or so history of studying out the roughly six major concepts of evolution, I have found that the early tenets of evolutionism were created so as to be in direct opposition and conflict with the creation accounts found through the entire Bible. Although it may be a bit more subtle today, I still find that the original paradigm and basis for creating evolutionism's major tenets hasn't changed up through to our modern time.
So in your mind evolutionary theory is a massive anti-Creationist conspiracy? Interesting...
