Today we have artificial selection which is the reproduction of two organisms with help from humans to create desired traits. You theorized that homologous and analogous structures helped support your theory of evolution. Three things you studied‚ homologous structures‚ analogous structures‚ and natural selection‚ greatly helped prove your theory of evolution among species. Homologous structures are very important when discussing the theory of evolution. Homologous structures are structures in organisms

In this essay I aim to explain Darwin’s theory of evolution through natural selection‚ contrast it with other similar theories set before it and then an overall conclusion. Darwin originally
