Give two examples of analogous and homologous structures by brainly
Answers
A Homologous structure is an organ or organ system present in organisms which share a common ancestry. These have a similar structure but different functions in different organisms. They usually appear because of divergent evolution and have same origin. A few examples are:
Vertebrate limbs(human arm patagium of bat, flipper of whale etc)
Brains
All vertebrates have similar structure of brain with all lobes.
An Analogous structure is an organ or organ system present in organisms which do not share an ancestry or common origin. They have a similar function but different structure. They usually appear because of convergent evolution in organisms found in similar habitats. A few examples are:
Wings of birds and insects
Fins
Potato and sweet potato,Both potato and sweet potato store food in plants in the form of starch but they have different structures. Potatoes are modified stems while sweet potatoes are modified adventitious roots.
