A point mutation is a mutation that affects only a single nucleotide of a nucleic acid. They involve substitution of one base for another which changes the complementary base as well in DNA, they may also involve insertions and deletions of a single base pair. I therefore think the point mutations in a DNA sequence may profoundly have an effect on the synthesis of proteins, or may also have no effect on protein synthesis at all. These mutations can be beneficial to an organism, however they are more commonly neutral or harmful.
Changes to the classification system have meant that the classification of some species of organisms has changed too. The system had to be changed to incorporate this new group or organisms.
