Are bat wings homologous or analogous?
Homologous structures: Bat and bird wings are homologous structures, indicating that bats and birds share a common evolutionary past. Notice it is not simply a single bone, but rather a grouping of several bones arranged in a similar way.
Are bird wings and bat wings homologous structures or analogous structures?
Bird and bat wings are analogous — that is, they have separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them to play a key role in flight. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous.
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 examples of homologous structures?
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.
Are bat wings and insect wings homologous?
For example, insects use wings to fly like bats and birds, but the wing structure and embryonic origin is completely different. These are analogous structures (Figure 2). Some structures are both analogous and homologous: bird and bat wings are both homologous and analogous.
How can a bats wing be considered a homologous structure and an analogous structure?
How can a bat’s wing be considered both a HOMOLOGOUS STRUCTURE and an ANALOGOUS STRUCTURE? Because the bones in the wings are similar to the to the bones in a human hand or in a mole foot. Also, the bones in the wings originated from insects, however insects do not have bones in their wings, whereas bats do.
Should bat wings be considered homologous to whale flippers?
Should bat wings be considered homologous to whale flippers? Which of the following is the best answer and argument? Yes. They have similar bone structure inherited from a common ancestor.
Are wings of bats and birds homologous?
Sometimes it is unclear whether similarities in structure in different organisms are analogous or homologous. An example of this is the wings of bats and birds. These structures are homologous in that they are in both cases modifications of the forelimb bone structure of early reptiles.
What makes structure of bird bat whale and human homologous?
An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.
What are homologous organs give two examples?
Homologous organ the traits inherited by two different organisms from common ancestry.
How are bat wings and human arms homologous structures?
A great example of homologous structures are the wings of a bat and the arms of a human. Bats and humans are both mammals, so they share a common ancestry. Both a bat’s wing and a human’s arm share a similar internal bone structure, even though they look very different externally. Besides, how are a bird wing and a human arm similar?
What makes up the wing of a bat?
The wing of the bat consist of petagium (flap of skin) stretched between the bones of the fingers and arm. The wing of the bird consists of feathers extending all along the arm. Bird and bat haven’t evolved from a common ancestor with wings.
What’s the difference between a wing and an arm?
The wing and the arm also perform different functions – wings help bats fly, while arms help humans interact with their world in a very different way. A great example of analogous structures are a bat’s wing and a bee’s wing. Bats and bees do not share common ancestry, so the structures cannot be homologous.
How are bats and humans alike and different?
Bats and humans are both mammals, so they share a common ancestry. Both a bat’s wing and a human’s arm share a similar internal bone structure, even though they look very different externally.
