Living things of the order Opliones, of which there estimated to be some 6,400 species, are members of the class Arachnida (arachnids). The theory of evolution cannot explain how one single protein or the first living element formed, much less why living things have remained unaltered for tens of millions of years.One of the fossils that silence evolutionists is the 50-million-year-old harvestman pictured. The way that harvestmen have remained unchanged for so long cannot be explained in terms of evolution. There is only one possible explanation: Creation.
