Indirect evidence, at least beyond the step of abiogensis, is overwhelming.
http://www.talkorigins.org/faqs/comdesc/ There are probably no documented examples of macroevolution that would satisfy you because what you're looking for are systemic functional changes in non-microscopic species, in the wild, which then forms a stable population as a separate species. Such changes are the accumulation of minor changes (which have been observed), but are not observable in aggregate in modern times because there has not been enough time to observe them. And if such examples were given, you'd say that's just a variation of an existing species. The perspective required to judge a separate species in your view is longer than the time phylogeny has been rigorously undertaken by scientists. You are asking for the impossible and using that to declare a theory you don't like as invalid. http://www.talkorigins.org/faqs/faq-speciation.html The GTE as you call it is not a finished theory. There have been significant changes in the past few decades (Lynn Margulis's work on endosymbiosis, for example), and there will be more changes in the future. Intelligent Design is not based on evidence. It is not falsifiable. It is not a scientific theory. It is a quasi-theory-of-the-gaps based on the assumption that the progress of evolution is too small and too slow to have resulted in humans. It ignores the mountains of indirect evidence pointing to macroevolution. ID rejects the theory of evolution on the grounds that there is too little direct evidence, or that the probability (not that anyone can calculate it properly, but Creationists pretend they can) of evolution is too low, and posits an alternate "theory" of a designer, for which there is no evidence, nothing that allows calculating a probability of such a designer, and which completely ignores where the designer came from, typically by punting and declaring the designer God, and stating that God exists inherently, which is riddled with assumptions, and regardless of whether it's true says nothing about the nature of that God or what it might want or do. |
Is that really true? Drosophila are used for genetic studies with a [shortest] breeding cycle of 7 days and have several ways to introduce mutations that would mimic natural mutagenic mechanisms [but accelerated] as well as being able to apply a lab version of selective pressure [which again would seem to be accelerated].
So far as I can tell we've been doing evolution experiments on drosophila since 1910 or earlier; but lets say a conservative 60 years. That's a potential 3000 generations. What's the least related variant?
For comparison the youngest Neanderthal ancestor is dated as 45000 years old (http://www.talkorigins.org/faqs/comdesc/section1.html#morpho...) which puts it within this order of generations.
Macro-evolution isn't rigorous. For example we've long been told it's incontrovertible that 'humans developed from a common ancestor with [knuckle-walking] modern chimps', that this should be believed as a facile result of evolutionary theory and holding out on that assertion is unscientific - http://www.talkorigins.org/faqs/comdesc/section1.html#morpho... is an example. Then some evidence is actually found http://www.nature.com/news/2009/091001/full/news.2009.966.ht... that disproves the assertion that was supposed to be based on sound scientific theory and evidence. But of course the theory stand unfalsified because it didn't demonstrate the result claimed at all, it was bad science in the first place.
But 'dogs definitely evolved from modern wolves though!' ... http://www.csmonitor.com/Science/2014/0117/Did-dogs-really-e....
But at least we have evidence of speciation and evolution of dinosaur features:
>"the diversity of dome shapes, and their association with boss and spike ornamentation, suggests that the domes were important for spe- cies recognition (Goodwin and Horner 2004)."
... and the following year everyone agrees that in fact that Dracorex, Stygimoloch and Pachycephalosaurus are just different aged version of the same animal (http://www.sciencedaily.com/releases/2009/10/091031002314.ht...). And there were similar results for other "species" of dinosaur.
I like this http://www.walkingwithdinosaurs.com/news/editorial/t-rex-gro... as an example of the type of thinking going on. The professor writing it is clearly holding on to the concept that you can give valid incite in to speciation and evolution based on the visual appearance of very limited fossilised remains despite the point of the article being that doing this in the past failed completely in producing truthful results.
It's seems pretty clear relying on "indirect evidence" isn't producing valid results in these cases.
On to your last para. There are enough holes in most Creationists viewpoints not to need to lie about the problems. You say creationism "completely ignores where the designer came from" but it's uncontroversial Christian theology [in common with the other Abrahamic religions] that God is eternal. 'Well who created God?' is the usual response. That, perhaps ironically, exactly mirrors one objection to the Big-Bang - the need for a prime mover. If the Big-Bang doesn't need a prime mover why does God, and vice-versa?
