The theory of evolution claims that in order for species to be able to evolve from one form to another, it must be in a constant state of change. In order for an invertebrate organism to turn into a fish—a needlefish, for example—it needs to undergo a succession of small changes over a very long period of time. Similar processes then have to take place in order for other species of fish to then emerge from the needlefish.
In the fossil record, however, there is not the slightest indication that such a process ever happened. As the 95-million-year-old needlefish fossil pictured here shows, life forms retain the same features they had when they first came into existence for as long as they survive.
