What is homologouse structure?
A homologous structure is a structure found in two very different animals that has a similar form in both animals. For example, the bones of a human hand are homologous to the bones in a bat's wing or a whale's flipper. Structures that appear very similar suggest that two animal may be related, as in humans, bats, and whales, which are all mammals.
Compare and contrate the bone of the bird's wing and seal's fliper?
Both the bird's wing and the seal's flipper are adapted for swimming, however they have different bone structures. The bird's wing contains long, lightweight bones with hollow spaces, while the seal's flipper has shorter, denser bones. The bird's wing has feathers for flight, while the seal's flipper is covered in skin to streamline movement in water.
The same basic array of bones are modified to give rise to the wing of a bat and the fin of a porpoise such anatomical structure are called?
Homologous structures. These are anatomical structures that have a similar origin in a common ancestor but have modified over time to serve different functions in different species. In this case, the forelimb structure of the bat's wing and the flipper of the porpoise are homologous structures.
What are the structures in the body that allows animals to move?
Bones, ligaments, tendons, and muscles allow animals to move.
Are the bones in your arm and hand comparable to bones in a whales flipper because of morphological divergence?
No
The bones in your arm and hand are comparable to the bones in a whale's flipper if we account for?
morphological divergence
How many bones in whales flipper upper limb?
356
What are the different types of leg structures found in animals?
Animals have various types of leg structures, including jointed legs found in insects, arachnids, and crustaceans; vertebrate legs with bones like in mammals, birds, and reptiles; and tentacles in some invertebrates like octopuses.
Which fossil are most common in the rock that is 500 million years old?
bones structures of animals
Do Dolphins front flipper and a bats wing?
They both contain skeletal bones.
What are the finger bones found inside of a whales flipper called?
The bones of the distal limbs are called phalanges (phalanx is the singular).
Why do all vertebrates have similar bone structures in the hand?
It is because the first animal to have a hand had a specific bone structure in that hand that was very well adapted. All vertebrate animals with a hand, wing, or flipper trace ancestry back to that first animal with a hand. The bone structure is modified slightly for each animal, but the organization of bones in the hand is the same among all the animals that have a hand.
