How does the modern theory of evolution explain the loss of vestigial organs? How does the modern theory compare with Lamarck's
Rzqust [24]

Answer:

Modern theory of evolution explains that "organisms change over time as a result of changes in heritable physical or behavioral traits". Hence this change suggests the loss of vestigial organs.

Explanation:

  • Vestigial organ are those which do not have any function but is present in our body.
  • According to the modern theory the genetic and physical appearance changes along with the adaptation in environment by the organism.
  • So if the organ looses its function in order to sustain and adopt in the changing environment then they become vestigial and slowly disappear.
  • This is the common example for the Lamarck's theory of "use and disuse".
