NCERT Solutions for Class 12 Biology Chapter 7: Points To Remember

Students can go through the following points to score well and achieve excellent results in the Class 12 Biology exam:

  • Evolution is often referred to as the study of the origin and development of life forms on earth.
  • Evolution answers questions like how did humans appear on earth and how different kinds of organisms exist in different habitats.
  • The first organisms could be single-cell organisms that lived in a water medium. These single-cell organisms eventually evolved into larger organisms over millions of years.
  • The expansion of the observable universe, according to the Big Bang theory, began with a large-scale and violent explosion of a small, primordial “super-atom.”
  • Homologous organs are found in forms that show adaptive radiation from a common ancestor, indicating ‘divergent evolution.’
  • Analogous organs are anatomically distinct and unrelated organs that serve similar functions.
  • Vestigial organs are rudimentary and non-functional organs that correspond to fully developed and functional organs in related organisms.
  • Molecular evidence entails determining evolutionary relationships by identifying conservation in DNA and protein sequences.
