Yes they are.
I disagree. Even if they ultimately come from a common ancestor, in order to classify two characteristics as homologous, they have to have some similarities. After millions of years of being in the oceans, the fins of whales have evolved such that they are not at all similar to cats' legs.
What else can I help you with?
Are arms wings and flippers homologous structures?
Among, say, mammals they are homologous, but the wing of an insect and a bat are analogous.
Are the wings of birds and the wings of bats homologous or analogous structures?
They are both. They are homologous because they are both examples of a vertebrate forelimb. They are analogous because they were adapted for flight independently of one another.
Is a wing of a bird homologous to the wing of a cat?
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
Birds and bees have wings are their wings homologous features or analogous features?
The wings of birds and bees are an example of analogous features, as they have evolved independently in each group and do not share a common ancestry that possessed wings. Homologous features are those that are inherited from a common ancestor and are usually more similar in structure.
Wings that look like flippers?
A penguin has wings that look like flippers. Penguins (several species) use their flippers to swim under water.
Are bird wings and butterfly wings homologous structures?
There are a few different similarities between the wing of a butterfly and the wing of a bat. Both are used to fly for example.
What is the difference between homologous structures and analogous structures?
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
What are penguins wings called?
The wings of a penguin are actually called flippers. They use them to swim and propel themselves through water. Penguins can not fly.
Bat wings and butterfy wings are what nonadaptive analogous homologous polypheletic monophyletic?
They are analogous. Both wings have developed from different origins, adapted for the same job, using different kinetics. "Analogous" is the only word you may use to define these wings. When you consider bat wings and butterfly wings, none of the other adjectives are scientifically correct.
How are analogous and homologous structures different?
They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.
Are the mouthparts of the two species homologous or analogous?
That depends on what two species you're referring to. Homologous parts are similar in structure and evolutionary origin, though not necessarily in function. for example: human arms and bat's wings Analogous parts, on the other hand function similarly, but may not be similar in structure or evolutionary origin. example: a butterfly's wings and birds' wings
How does penguin move?
On land they waddle. In the water they swim using their wings like flippers.
