Describe how fossils provide us evidences in support of evolution.

Solution

Fossils provide a unique view into the history of life by showing the forms and features of life in the past. Fossils tell us how species have changed across long periods of the Earth’s history.

Importance of fossils in the evolutionary process:

  • Some invertebrates living on the sea bed died and were buried in the sand.
  • More sand was accumulated and formed sandstone under pressure.
  • After millions of years, dinosaurs living in the area died and their bodies were buried in the mud.
  • The mud got compressed into the rock, just above the rock containing earlier invertebrate fossils.
  • Again millions of years later, the bodies of horse-like creatures dying in the area were fossilised in the rocks above the earlier rocks.
  • Much later, because of erosion and water flow, some rocks wore out and exposed the horse-like fossils
