Convergent evolution leads to analogous structures. Explain with the help of an example.
✓

Answer

Convergent evolution is the evolutionary process, where anatomically different structures in different groups of organisms evolve towards the same function, in similar habitats.
  • Such structures in different groups of organisms which perform similar function, but are anatomically different, are called analogous organs.
  • The tuber of potato (stem modification) and the tuber of sweet potato (root modification) are analogous as they perform the function of storage of food.
