“The greatest service which can be rendered to any country is to add a useful plant to its culture.” –Thomas Jefferson

The Darwinian approach of Natural Selection asserts that species adapt to various environments. Selection is the process by which the organisms that are best adapted to their environment tend to be the ones that survive to reproduce and pass on their genes to the next generation, hence the term ‘survival of the fittest.’ The environment is the ‘genetic sculptor’ which can, over time, change the characteristics of the organisms within a population.
