Darwin’s theory of evolution states that “by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment, compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation”. The grouping of organisms in the classification table is not just the result of similarities, colours, ecological functions, etc, it also covers and expresses information about our understanding of the evolutionary history of these groups. Another part of Darwin’s theory of evolution that has an effect on the classification table is natural selection, which is the process where “organisms that better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution”. Over time organisms have evolved to adapt, to their new or ever changing environment, different predators and natural selection. An example of these adapting animals are the great white shark and the fern.

Two organisms that adapted over time are the great white shark and the fern. The great white shark is a large fish, with a torpedo-shaped body, 5 gills slits, an anal fin, no fin spines, pointed snout, crescent- shaped tails, and 3 main fins which are the dorsal fin which is on the back of the shark and the two pectoral fins which are on the shark’s side.
