Thousands of species inhabit this earth frommicroorganisms to terrestrials. All of this diversity derives from a common ancestor.As time passes, inherited traits create speciation, which is the formation ofnew species due to lineage splitting. Genetic diversity plays a vital role inan organism’s adaptability. If a population’s environment changes, thepopulation will either adapt in order to survive or they will go extinct. Natural selection is a process that is required forevolution.
It is when traits that increase fitness are passed from generationto generation, it also allows all generations to survive. Nevertheless,characteristics that are not fit for the environment and survival are notpassed down due to the fact that most individuals carrying the trait will notlive to have offspring. Natural selection is a product of changing to adaptmore effectively to the environment itself.

“Extrapolation of these results suggest that, ofthe estimated 70,000 species still to be described, more than half already havebeen collected and are stored in herbaria” (Herbaria are a major frontier for species discovery,2010). Thousands of new species are discovered every year because of evolution.Especially with global climate change, animals must adapt with the new environment.
