Evolution Meaning and Types


  • We all have heard people normally saying “humans come from monkeys” whenever a child jumps around or eats a lot of bananas.
  • Have you ever thought if this statement is actually true or just an equivocate?
  • Oh!! A question just popped in my mind, if monkeys are the ancestors of humans, do all plants, animals, insects that we see around also have some ancestor.
  • We are going to find answers to these questions in this chapter.
  • Evolution - study of slow,continuous, and irreversible change in different species from simple to complex beings in order to become better adapted towards the changing environment.
