If we are to accept the teaching of
macroevolution as true, we must believe that mutations and natural selection did produce all complex life-forms, despite the last 100 years of research showing these have never created anything entirely new.
Never created anything new? Really?
There are new strains of yeast, bacteria, virus, mold, and fungus discovered each year in places where they never existed before.
There are bugs that have evolved to resist GMO crops in India (I think it was). GMO is vegetable (mostly corn, soy, and some other plants) that have been altered by Monsanto in the past 20 years to create its own pesticides. It's an artificial plant to resist bugs. Now... 10 years after the use... there are bugs that have resistance in turn against the plants pesticides (created by humans). Were did they come from?
We see this all the time. New bugs, new virus, new everything that fights against human attempts to keep us safe, happy, and healthy.
Where did MRSA come from? It didn't exist 50 years ago. No where. Today, it's not only on the rise, but several other super-bug strains have evolved. They didn't exist before, and by vector analysis they have found were some of these new strains started. Mostly in hospitals. In hospitals that didn't have those bugs at all before, and suddenly... boom, there's a new kind of virus.
So nothing new?
There's actually a lot, a huge amount more of this, if you only took your time to put some interest and read about it.
In beer brewing, there are now hundreds of strains of yeast for the process. Some of them for lager (below 50 degrees fermentation) and ales (70 and above). There are new strains of hops, like the more bitter hops that didn't exist on the market some 15 years ago. These have been created by selection, instead of natural selection you pick and play "nature" for the plants and reproduce those plants and pick the ones you want, and so on, until you have picked the mutations that you prefer. The same was done with dogs and all the breed the past couple of hundred years. Dalmatians didn't exist some hundred years ago. They were bred by taking the "kind-a" dalmatian like and let them reproduce, and then you pick the ones with a more-kind-a dalmatian look from the offspring, and so forth. This is done with plants too. You find them in the store right now. Tomatoes, apples, ... all artificially selected and bred to become something more pleasing for the shopper. Bananas are another example. Or take the tusks on the elephants. Can you explain why they have smaller tusks now?
