Evolution theory goes beyond

OPINION - As a Wallacean and Darwinian, I have always viewed life from the perspective of evolutionism. I see the world of plants and animals always using evolutionary theories. How a species develops functional organs, forms morphology, adapts to ecosystems and so on as a natural laws. This perspective ultimately forms my framework for thinking about various things, including the way I see myself, everyday problems and the way I think about big things such as economics, geopolitics, war and so on using an evolutionary perspective. Alfred Russel Wallace, Charles Darwin and Jean-Baptiste Lamarck are three great figures who really inspired me. They are well known as pioneers of evolutionary theories. They start from small things in the sub-subject of biology, although they also discuss geology and so on. Wallace focused on species adaptation and Darwin on sexual selection. Both developed evolutionary thinking using observational methods. Lamarck focused on structural morphology using l
