can u tell the difference between homologus and analogus organs?And give one example?

Question

Answer

Answer

Answer

Answer

homologus organ:-same structure but different function.eg-hand of man and feet of horse.analogus organ:- different structure but same function.eg- wings of bird and butterfly.

Answer

Homologous organ: Organs which perform common origin and structure but different function.

Examples:- Forelimbs of amphibian, reptiles, birds, mammals.

Analogous organ: Organs which perform similar function but have different origin and structures.

Examples:- Wings of bat, birds, insects, butterfly.

Answer

I tell briefly actually it is a one word answer k  na @ muskan

Answer

HOMOLOGUS: they show a common pattern in the arrangement of bones, even though their external form and functions are different. It indicates that all the vertebrates have evolved from a common ancestor and these organs are called homologous organs. This type of evolution is called divergent evolution.EXAMPLE:leg of a cheetah (runner), claw of a moleANALOGUS:structurally different but functionally similar are known as  ‘Analogous organs’. This type of evolution is called convergent evolutionEXAMPLE:we find that the wings of bats have skin folds (patagium) stretched between elongated fingers. But the wings of birds have a feathery covering all along the arm. The designs of the two wings, their structure and components are different. They look similar because they have a common use for flying, but their origin is not common.

Answer

I know the difference between the two organs

Answer

Homologous Organs:
Homologous organs are those that have a similar structural design but may have different functions. These organs are derived from a common ancestor and share a basic structural blueprint. Homologous organs are evidence of divergent evolution, where different species have evolved from a common ancestor and adapted to different environments and functions.

Example:
One example of homologous organs is the forelimbs of vertebrates. The forelimbs of mammals, birds, reptiles, and amphibians all have a similar bone structure, with a single upper arm bone (humerus), two lower arm bones (radius and ulna), and a set of bones in the wrist and hand. Despite the variations in size, shape, and function, these forelimbs share a common structural plan, indicating their evolutionary relationship.

Analogous Organs:
Analogous organs, on the other hand, are those that have a similar function but different structures. These organs are not derived from a common ancestor and do not share a common structural blueprint. Analogous organs are evidence of convergent evolution, where different species independently evolve similar traits to adapt to similar environments or perform similar functions.

Example:
A classic example of analogous organs is the wings of birds and insects. While both birds and insects have wings that enable them to fly, their wing structures are fundamentally different. Bird wings are formed by modified forelimbs covered in feathers, while insect wings are made of thin, membranous structures supported by a network of veins. Despite the differences in structure, both bird and insect wings serve the same function of flight, but they have evolved independently in response to similar environmental pressures.

Summary:
In summary, homologous organs have similar structures but may have different functions, indicating a common evolutionary origin. Analogous organs, on the other hand, have similar functions but different structures, indicating convergent evolution. Understanding the differences between homologous and analogous organs helps us gain insights into the evolutionary relationships and adaptations of different species.
