What is an example of homologous structures?

Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats. ... An example of this are the wings of a bat and the wings of a bird.

What are 3 examples of homologous structures?

Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.

What are homologous structures and give an example?

Homologous structures are structures having a similar origin, similar development, similar internal structure and basic plan but showing different external form and function. Example - Forelimbs of mammals, birds, reptiles and amphibians.

What is another example of homologous structures?

A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.

What are homologous characters give an example?

We use homologous characters — characters in different organisms that are similar because they were inherited from a common ancestor that also had that character. An example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs. Sharks and bony fish do not.

What are some examples of analogous and homologous structures?

Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.

Is eye of octopus and mammals?

They have homologous structures. Note: The eyes of octopus and mammals (such as humans) both evolved the same thing but they are different animals. But in vertebrates, all developed different versions of the brain from the same evolutionary brain.

What are homologous organs give two examples?

Homologous organs: These are organs having a similar structural plan, but different functions. For example, the wing of a bat, the flipper of a seal, the front leg of a horse and the arm of a man perform different functions, but have the same structural plan.

Is a frog homologous or analogous?

Forelimbs of frogs and lizards are the example of homologous organs. ... The hoping legs of the frog contain the same bones as a lizard's forelimb, the humerus, the radius, and the ulna but the frog's legs are highly modified to perform a different function (hoping) and lizard's leg for locomotion.

Which of the following are best examples of homologous structures?

The correct answer is (B) Bat wing and human hand. Homologous structures are similar structures that arise through divergent evolution from a common...

Is a dragonfly wing a homologous structure?

When organisms share similar characteristics along with a common ancestor, we say that their characteristics are homologous structures. The wings of butterflies and dragonflies are homologous structures.

Are birds and whales homologous?

Whales, lizards, humans, and birds all have the same basic limb layout. ... Its descendants, including whales, lizards, humans, and birds, as well as many others, inherited the tetrapod limb from this ancestor. Structures inherited from a common ancestor are called homologous structures, or homologies.

How are homologous structures An example of evidence of evolution?

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

What is an example of analogous structures?

For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying. The presence of the analogous structure, in this case the wing, does not reflect evolutionary closeness among the organisms that possess it.

What is vertebrate homology?

Many vertebrate species share common evolutionary ancestors, and thus have homologous traits. Homologous traits are traits that are similar to one another due to shared ancestry.
