The evidence in favor of common descent is overwhelming. Fossils, genetics, morphology, ect all point to the same conclusion.
We have witnessed speciation events. We understand how mutations work. New "information" can be created and this has been witnessed multiple times. There is no magical barrier preventing "macro"evolution.
Note that the term macroevolution originally described change in form as seen in the fossil record. The use employed by creationists is dishonest and inaccurate.
Edit: The entirety of the fossil record is exactly what one would expect if evolution was correct. The order of the geologic column alone speaks volumes. Why are there no bunnies in the Cambrian?
As for genetic evidence, here is a small bit. Humans have 23 (haploid) chromosomes. All other apes have 24. If common descent is true, then at some point both groups had the same amount.
As it turns out, human chromosome 2 is clearly the result of the fusion of two separate chromosomes. Account for this and the karyotype is identical.
For a small, yet dramatic, example of new "information," there is the enzyme nylonase. Since nylon wasn't invented until 1930, it clearly had to be new. We even can tell how it was formed. A gene duplication followed by modification.
Creationists are without fail utterly ignorant of biology.
Edit: The order in the geologic column is more primitive species are deeper. This is simply a matter of one layer on top of another. No dating is involved. You can't wish away this fact.
The no bunnies comment refers to the fact that no vertebrate of any kind has ever been found in the Cambrian. Find a single one and evolution would be disproven.
Similarity does indicate common descent. Not only was this a predictions made by evolution, it makes no sense from a special creation viewpoint. Why would god make interior telomeres? To confuse us?
Not only does all of biology unanimously support evolution, the predictions it makes are accurate and save lives.
Not only are you wrong, you are trying to tell a biologist one of the most useful and powerful tools in science is a lie. Get an education.
