Question

Bacteria have a simpler body plan when compared with human beings. Does it mean that human beings are more evolved than bacteria? Explain your answer.

Answer 1

Despite the fact that humans have a more complex body plan than bacteria, it does not mean that they are more evolved than bacteria. Bacteria still inhabit some of the most inhospitable habitats such as hot springs, deep-sea thermal vents and ice in Antarctica. Most other organisms cannot survive in such harsh environments.
