In geomorphology/geology, and in biology I discovered that forms of something are cl;aimed to have had different origins. In geomorphology, just three examples, are how great canyons were agreed to have been caused by a megaflood in one day, like the mIssoula flood and others, that completely mimic what other canyons look like but are said to have been created over great timelines even millions of years. Another case is how salt stagimites(sp) , created instantly in a day or so, look exactly like other stagimites , made of other elements, that are claimed to have taken large timelines, thousands of years, in caves to grow. then in meteorites they have found tiny tiny diamonds(I think in meteorites) that they conclude were created instantly, a moment, from great heat/pressure WHILE still saying regular bigger diamonds were created from long timelines, millions of years.In biology there is the famous convergent cases of marsupials looking spot on like non marsupials in forms like dogs, cats, mice.
I say that in all these cases its not just that having proven a origin for one form that allows us to say its the origin for any like form BUT that on a probability curve its very unlikely that the origin hypothesis for the forms, not proven/witnessed , are right. not just unneeded but very prompting they were wrong. they were speculations about long timelines that were used until modern investigation proved, for like firms ,were rapidly created.That in these cases real time math/probability really can correct errors that are in opposition to creationism.
