What are homologous and analogous organs
Answers
Explanation:
homologous organs :the organs which have same basic structure or origin but have different functions.
example,forelimbs of human, lizard, frog.
analogous organs: the organs which have different structure or origin but have same functions.
example, wings of insect, birds, butterfly.
Homologous and Analogous Organs
Step by step explanation:
1) Homologous Organs: These are defined as those organs that have same anatomical origin but performs different functions. This therefore, indicates that the organisms have evolved from same ancestral origin but performs different functions according to the surroundings.
Example: Forelimbs of cheetah and the forelimbs of humans
Wings of bats and wings of birds.
2) Analogous Organs: These are defined as those organs that have different anatomical structure and origins but performs the same functions. This therefore, indicates that they have not evolved from the same ancestral forms and have different origin.
Example: eyes of octopus and eyes of mammals. Birds, insects and bats have evolved from an ancient common ancestor without wings.
