A very common type of mutation is duplication, and it happens a lot during crossing over in meiosis. How could duplication possibly not be increase in information? You might think two copies of the same information doesn’t increase information. It is just a matter of time before DNA Polymerase (the enzyme that copies DNA) creates another mutation by changing a nucleotide of one of the two copies. We now have two genes, coming from a single gene. These changes are called SNP’s - Single Nucleotide Polymorphisms, and are used in DNA tests that identify who is the father of a given child. Mutations are caused by natural copying errors, and chemical/physical mutagenics. If you deny this you deny the existence of the many children who are born with genetic diseases every year. You deny the existence of those prostitutes in Kenya who are resistant to HIV, those people in Italy who are immune to dangerous cholesterol accumulation in the walls of their arteries, and so on… Well, prostitutes who resist HIV and Italians who eat a lot of pork without being worried about heart attack are seriously more likely to survive and have more children than those people who die with AIDS and cholesterol in the aorta. How can that be denied? These mutations are in the same population with the so-called wild type of the gene, and they increase in the environment these human populations live.
