Question

what are homologous organs and analogous organs

Answer 1

Hello dear your answer......
Idon't my answer is wrong than please inbox me or say me in comment.......


homeo logos structure is an organ,system or body part that shares a common ancestry in multiply organism.this definition is found in evolutionary biology and use the meaning of having a similar structure or Origin...

Example if Homologous organ=the arm of a human,the wing of a bird or bad ,the leg of a dog and the flipper of a donphin or whale.they are the friends and have a different purpose but they are similar and their common traits....


Analogous organ....


analogous organs are the opposite of homologous organ which has similar function but different origin.....

Example if Analogous organ=the wings of insects,bats and birds that evolved independently in each lineage separately after the wording from an ancestor without wings.....




Photo in first is if Homologous and in last is of Analogous organ....

Thanks!!

Answer 2

Homlogous organs: Organs that have same basic structural design but have different functions are called homologous organs. Eg. The forelimbs of frog, human, lizard and birds.

The forelimbs of humans help in grasping, of lizards help for running, of frog for hopping and of bird for flying.

Analogous organs: Organs that have different basic structural design but perform similar function are called analogous organs. Eg. Wings of birds and wings of insects.

They have same function i.e flying but have totally different anatomy and origin.
