While Gould occasionally toyed with saltationism, he never seriously proposed it, and as far as I know Eldredge never had anything to do with it. Punc. eq. is not saltationism. The former proposes different tempos (and locations) of phenotypic evolution within species and during speciation, while the latter proposes that major phenotypic change occurs in a single generation because of one mutation.
ID makes a much more specific claim: the presence of intelligent design can be detected scientifically. Itâs making scientific claims.
Splendid! If you understand how life on earth evolved, you shouldnât have any trouble telling me how you would evolve a two-cell organism from a one-cell organism ⌠which in the grand scheme of things, is a very fundamental evolutionary progression. So, what would be your first step in achieving that basic evolution?
Alternatively, what would be your first step in making a prokaryote evolve into a eukaryote? Thatâs another very fundamental evolutionary progression, so your knowledge of evolution should be able to easily cope with that basic task too.
I would say that Godâs sovereignty over âlucky coincidencesâ can bring molecules together and mutate them wherever, whenever and however he pleases has all the bases covered (yeah, including ACGT). Thatâs all I need to know since I am not in a research position where I would be trying to investigate further. Tell me again how you believe in Godâs sovereignty.
I wouldnât, since itâs quite unlikely that single-celled organisms evolved into two-celled organisms. Far more likely is that single-celled organisms evolved to form colonies of identical cells (which we can see readily today), which then evolved into colonies where some of the cells took on specialized roles (which we also see today).
Well said. It was studying the complexity of the cell that convinced me that there must be a Creator.
Yes, our intuition is correct, that there is a Designer. Our intuition is incorrect however, when it concludes that ID is science. Youâve heard of exaptation, I presume.
@DGX37, I would agree. I would also say that even if phenomena can be explained naturalistically or in terms of material causes that it does not mean that God was not involved in the process. Thomas Aquinas, for example, taught that God works through nature. He would not have had a problem with the idea of God using geochemistry to create life or evolution to create new species. God created the universe. Science just uncovers the âtechnologyâ that God used to create it.
No, Iâve never heard of exaptation.
Big words scare me, and âexaptationâ is a very big word.
Itâs the same length as âprokaryoteâ which you used above. Wikipedia is our friend (most of the time ; - ).
So youâre saying is more likely that single-celled organisms formed colonies, which in turn formed the first multi-celled organism(s)?
If so, thatâs a fascinating idea ⌠but I bet scientists have fun trying to figure out how that could have been coordinated!
Time to pull put out the âGod done itâ card again, me thinks.
I wouldnât disagree with that, but by pulling out the âGod done itâ card as an explanation, youâre admitting that you donât understand how evolution works.
I mean, if you donât know something as basic to evolution as how to produce (evolve) a eukaryote from a prokaryote, then you can hardly claim to understand how evolution works, can you?
I doubt if anyone in research has ever produced (evolved) a eukaryote from a prokaryote, so they wouldnât know either - in fact, I would venture to say no scientist on the planet would have the foggiest idea about how to produce a eukaryote from a prokaryote.
So on that basis, I think it would it be fair to say no one really understands how evolution works.
Thereâs a difference between understanding the mechanisms of how life changes and the specifics of how life changed for one specific example. We donât throw out our understanding of how geology works just because we donât know the entire history of a single geologic formation.
We can look at nested hierarchies and DNA sequences and say yes, we know how evolution works. We can also look at Godâs providential timing and placing of events (the DNA mutations and the solar eclipse in my nephrectomy account, for instance) and know that he is in control. You appear not to have looked through the conversation I referenced above, Questions about nested hierarchy.
Well put. Â
The progression from prokaryote to eukaryote is one of the most basic and primative progressions in the evolutionary story. If one doesnât know even the first step of how to achieve that progression, one can hardly claim to know how evolution works, I should think.
That confuses two meanings of âbasic.â Thereâs a difference between basic as bedrock and basic as simple. Itâs like saying, if we donât know something as basic to gravity as what a graviton is, we can hardly claim to understand gravity. (Or to move outside of science, if we canât pin down something as basic to Christianity as how the atonement works, we canât claim Jesus saves.)
Scientists understand quite a bit about how evolution works by studying what they do have easier access to. The mysteries that remain in understanding transitions for which less evidence remains donât make what we do know go away. And theyâve made enough progress on even the hard questions that it would be foolish to wager oneâs faith against them.
That is sort of like telling my pastor that is he is not fluent in ancient Hebrew, he has no idea what the Bible says. Certainly, it would be nice to be fluent, as there are words we still do not really know the meaning of, but we can get a pretty good idea based on context and what we do know.
You are confusing history with mechanism. They arenât the same thing.
The reason we donât know how prokaryotes evolved into eukaryotes is that we donât have enough evidence from that period in history. It isnât a matter of not understanding how evolution works. Itâs a matter of not having the evidence necessary to know which specific evolutionary pathways were taken.
Letâs say you are a crime scene investigator. At a murder scene you show up just a few hours after the victim died, and the crime scene is loaded with evidence. Thereâs a bloody knife with the criminalâs fingerprints, hair from the criminal, bloody shoe prints from the criminal, etc. Itâs easy to understand the mechanisms of how this person died. At another scene there is just a skeleton. There isnât any real evidence you can find to determine how the person died.
Now, would it be fair to say that you canât know how the murder victim died at the first scene because you canât identify how the other person died? Obviously not. You know of many ways of how a person can die, and can understand the mechanisms of how a person dies when there is ample evidence present. On top of that, would someone be justified in claiming that the second person died because of evil Leprechauns simply because you couldnât determine how that person died?
If I asked you how a sheep dog can be produced from a wolf, you would be able to tell me how to achieve that evolutionary progression. But you canât tell me even the first step required for producing a eukaryote from a prokaryote. That suggests you donât really understand how evolution works.
