Before I comment further, I would like to clarify then. Is it correct to assume nobody disputes that there can be changes to protiens where an "old" protein takes on a new function? (ex.1 a kinase protien mutates and gains the ability to phosphorylate a different type of sugar, or gains the ability to also dephosphorylate  the sugar as well)(ex.2  only protiens that give rise to thick coarse hair and thin hair exist. Now the DNA that gives rise to thick hair is mutated to give rise to curly hair.. now all three can be found in the population)-- clearly 2 is a hypothetical ( I know nothing about human genetics for all I know these types Of traits are controlled by 12 genes)It's just an example trying to illustrate the type of change I'm referring to.

If these types of changes can occur,Then over time they would accumulate. At some point these simple changes would then cause groups to no longer be able to interbreed, gain the ability to metabolize new food sources, change skin and hair colour, change size etc. Eventually generations later(many many many later) would not resemble what the original parents started out as. I understand that creation science says baramin sometimes can no longer interbreed due to "degeneration of information" or some similar term, but at what point would it no longer be the same type of creature.

I've heard people say that this doesn't happen, but it works at the molecular level (changes like  paragraph one of my response), we see it every day in labs. If you accept (again I suppose I don't know that you do) that changes like in paragraph 1 of my response do occur, why would they then not simply accumulate until the offspring of thousands and thousands of years later don't resemble the original  generation.
 +
At what point are these changes stopped from occuring/ accumulating? by what are they stopped? and at what point is this evolution?
 +

In regards to new information I guess that depends on your definition of "new" as well. gene duplications occur all the time. These then can have their original functions altered ( see example 1 and 2) now the organism in question has 2 genes with two similar functions that are different and useful, and that can be passes on to subsequent generations. This second gene can be altered further or duplicated itself in subsequent generatons,(of course influenced by it's enviroment; it will not change or loose the only copy of something required in a given environment. Eventually the parent protein no longer resembles the desendent from thousands of years later.

Gene timming is also huge using the same protien in different ways.  A promoter ( or operator)..or the proteins that interact with the promoter (or operator) can be altered. Now the gene is "ON" at a new time.At the molecular level situations like this are observed in a labs. Using  your cake analogy this would be like taking melted chocolate that goes in with flour for flavor, instead on the cake.Not a "new" information exactly but a new use that would be a different product.Timing body plan genes (hox genes???) can create drastically different looking creatures.( duplicating body plan genes also has a large effect I believe?)

If these change accumulate,the creature looks and acts differently in a new niche, wouldn't it be correct to say this is evolution.
 +
 +
We may not have observed enough accumulated changes to be what you would accept as a complete new species , (It is very unlikely that we could have yet, due to time constraints ie. how long we have been observing) however, we have observed many of the molecular mechanisms. They wouldn't just stop working because over time it could/would lead to evolution.
 +
 +
As for where the first genetic information ever came from.. that is origins of life not evolution, and though there are theories, this is much less experimentally sound science at the moment.( not to mention a whole other discussion)
