About Vestigial Organs And How Evolution Supports Such Organ

How do the vestigial organs support the theory of organic evolution?


In python and whale, we find the vestigial remains of hind limb and pelvic girdle,functionless wings are present in Kiwi bird and the splint bones in the hind limbs of horse are few examples of vestigial  structures.These had been fully functional in their ancestors,but have been reduced in size and activity in the representative forms.This is a very strong evidence for evolution,because this has  happened due to ‘decent with modification.’
