It is true that we as humans share 90% of our Genes with Apes... But it is also true that we share 50% of of our genes with bananas. I hope I'm not half banana. Also we share 100% of our genes with... Dirt! the exact substance god said he made us out of.
Another problem is that one of the ideas behind macroevolution is competition, or survival of the fittest. Different animals in a species compete for food, and whoever is the fittist lives, creating a stronger species. However, many animals are part of a symbiotic relationship which is the opposite of competition. Also, many animals live together and hunt in packs.
