Darwin reasoned that natural selection organisms had adapted to new environments, giving rise to new species. It is a principle of speciation.
<h3>Speciation, natural selection and environment</h3>
Different environmental pressures (e.g. the type of food) lead to different evolutionary pathways in genetically related organisms.
The organisms subject to different environments evolve as a consequence of natural selection in order to adapt (adjust) to their corresponding environments. 
In consequence, this process may eventually lead to speciation due to the emergence of reproductive isolation barriers.
