Not necessary, it is possible to get the same thing broken in different cases, by the same method it happened in some case.
The chance of that happening is 1 in trillions upon trillions.
The chance of it being the result of a common ancestor passing on the broken gene to all offspring is.... 1 in 1.
Off-spring inherits DNA from parents.
The same mutation happing twice is ultra-rare. Three times mega-ultra-rare. It only gets exponentially worse the more instances you add to it.
You apparently prefer odds that are even worse then winning the lottery dozens of times in a row as opposed to an explanation where sharing this broken gene is not only probably but even
inevitable.
You should question your rationality in this preference.
And that all species evolved to this diversity from single cell is several times more improbable.
It is not actually.
But I understand that you would think so, given your baffling and embarassing lack of understanding of the process. You don't even seem to be properly comprehending the implication of the process of reproduction where parents pass on their genes to their children...
It is. Take ERV's for example.
We share PLENTY of ERV's with the other great apes.
And ERV is the result of a viral infection where it gets inserted into the genome (and subsequently inherited by offspring).
There are ~3000 of viruses which can do this.
In our primate genome, there are about 3 billion possible insertion spots.
Meaning that sharing 1 ERV with another individual WITHOUT sharing ancestry, the chance is 1 in 3000*3 billion.
Sharing 2 such ERV's would be 1 in (3000 * 3 billion) ²
Sharing 3 such ERV's would be 1 in (3000 * 3 billion) ³
Sharing 20 such ERV's would be 1 in (3000 * 3 billion) ^20
And so on.......
With the ERV forming in a common ancestor who then passes it on to offspring and then having those descendants share those ERV's would be...... 1 in 1.
And it is like that with pretty much ALL shared genetic features.
Count them all up. Consider the
trillions upon trillions upon gazibillions of lottery wins you require to "handwave" that away.
All the while the probability in context of common ancestry is ... 1 in 1.
This is the level of "absurd" you need to appeal to in order to defend your myths.
It can be seen that offspring is not identical to their parents, there are variations in between certain limits. For example the color and size of people can vary, similarly as with all living things. But we don't see for example mouse turning into a mini whale, which should be possible, if the evolution theory is correct.
No. Hilariously, if we would observe such a thing, evolution theory as presently understood would be disproven.
You might want to read up and inform yourself before making an even bigger fool of yourself.
This is really ridiculous.......
This is why I can believe there was for example one kind of bears and all modern bear "species" are offspring of those.
Hilariously, to believe that, you would have to believe in "super duper evolution on steroids" to account for all these new species in only a few millenia. It would require evolution to work at a rate hundreds of times faster then presently understood and observed.
And off course, as already stated, your ad hoc explanation simply doesn't work..........
You invent this ad hoc nonsense to "explain away" the shared genetic features of bear species.
But the exact same kind of shared genetic features exist between all bears and all other mammals.
On a deeper level still, the exact same kind of shared genetic features exist between all mammals and reptiles.
On a deeper level still, the exact same kind of shared genetic features exist between all mammals / reptiles and vertebrates.
Etc etc etc.
Until we indeed end up with primitive prokaryotes.
You are drawing completely arbitrary lines here which do not exist, do not make sense and which are simply absurd.
And all of it is ad hoc nonsense based on nothing but scientific ignorance and religious bias.
