B: homologous structures. The beak of a bird and the beak of a squid are both used to help obtain food. These are likely A: homologous structures.
These structures support the idea that the different animals descend from a common ancestor and serve as evidence of evolution. In other words, these examples of homology occur when very different animals have bones or other structures that appear very similar in form but not in function.
Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor. The tailbone in human beings is so-named because it is a homologous structure to the beginning of many animals' tails, such as monkeys.
All mammals share the homologous structure of the vertebrae in common. For instance, in spite of its height, the giraffe has the very same number of neck bones (seven) as a giant whale and a tiny human being. Human beings, dogs, and cats all have similar pelvises, which are homologous structures to a vestigial pair of bones in snakes.
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. They are considered homologous structures because they have a similar underlying anatomy.
Homologous structure. Structures that are similar in different species of common ancestry.
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.
Answer and Explanation: D. The forelimb of a dog and the forelimb of a cat - These structures are similar and imply common ancestry.
Examples of homologous structures are the bones of a cat's leg, bird's wing, whale's flipper and a human arm. They are homologous because they formed from the same embryonic tissue but developed into different mature structures.
Homologous Structures. Homologous structures are when two organisms have a similar structure but have a different function.
A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Although these two structures do not look similar or have the same function, genetically, they come from the same structure of the last common ancestor.
Homologous organs : The organs which have the anatomically same structure but are different in functions are called homologous organs. Examples of homologous organs are as follows: Mouth parts of cockroach, honey bee, butterfly. Forelimb of man, whale, bat, cheetah.
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.
Human beings, dogs, and cats all have similar pelvises, which are homologous structures to a vestigial pair of bones in snakes. These bones in snakes are the last remains of a pelvis, with no legs to attach.
The correct answer is (B) Bat wing and human hand. Homologous structures are similar structures that arise through divergent evolution from a common...

They have a differing function so a wing versus an arm versus a fin for example.
Closer inspection demonstrates that in terms of form and function, gastropods (like snails), cephalopods (like squid), and bivalves (like mussels) share this homologous structure in common. All organisms contain homologous plasma membranes with what is called a phospholipid bilayer.
What is a homologous structure? It is an example of an organ or bone with similar underlying anatomical features found in different animals. These structures support the idea that the different animals descend from a common ancestor and serve as evidence of evolution.
It is known as a " vestigial structure " because it is the last vestige of what was once a tail. This structure serves as evidence of having a common ancestor, one that would have had a tail. All mammals share the homologous structure of the vertebrae in common.
A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures. Whereas human beings have bones such as the humerus (upper arm), ulna and radius (forearm), carpals (wrist bones), metacarpals (hand bones), and phalanges (fingers), these features appear as similar bones in form in the other animals.
