Bacteria have a simpler body plan when compared with human beings. Does it mean that human beings are more evolved than bacteria? Provide a suitable explanation.
Evolution is simply the generation of diversity and the shaping of the diversity by environmental selection. The only progressive trend in evolution seems to be that more and more complex body designs have emerged over time. If evolution is viewed in terms of the complexity of body design then human beings are more evolved as they have most complex body designs. However, if evolution is viewed as the ability to survive in extreme conditions then bacteria is more evolved compared to human beings as bacteria can survive under the most extreme conditions. Many bacteria live in Sulphur springs and in craters of volcanoes.
