Are bat wings and whale flipper homologous?
Encyclopædia Britannica, Inc. When two or more organs or structures are basically similar to each other in construction but are modified to perform different functions, they are said to be serially homologous. An example of this is a bat’s wing and a whale’s flipper. An example of this is the wings of bats and birds.
Are the legs of a cat and the fins of a whale 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.
Why are the wings of bats and birds homologous?
Bat wings and bird wings evolved independently and are considered analogous structures. In the above example, the bird and bat wings are analogous as wings, but homologous as forelimbs because the organ served as a forearm (not a wing) in the last common ancestor of tetrapods. Analogy is different than homology.
How is the wing of a bat similar to the flipper of a whale and the arm of a human?
A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.
Does human arm whale flipper and bat wing belong to a common ancestral group?

What is the classification of human arm and alligator forelimb?
Answer. Classification of human arm and alligator forelimb: Humans share their structure with some vertebrate animals these structures are called homologous structures. For example, a human arm and alligator forelimb both are having the same homologous structures.
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 the function of a alligator forelimb?
Like the fins of a fish, they prevent the animal from rolling uncontrollably in the water, and also help to stop it from sinking – although the air in the crocodile’s lungs is primarily responsible for that.
Do crocodiles stand on their hind legs?
Crocodiles are known for their short legs, scaly skin and mighty snap. However, new research suggests the reptiles may have once walked on two hind legs!

Can crocodiles walk on two legs?
In addition to walking on two legs, it left a very narrow trackway, “putting one foot in front of another,” unlike modern crocodilians, Lockley says. The idea of a bipedal crocodilian might seem bizarre, but it is not entirely unheard of.
What is the function of a cat arm?

How does CAT tool work?
A CAT tool divides the text to be translated into TUs and presents the segments clearly to make translating easier and faster. Smartcat shows each segment in a box, and the translation is entered in a separate box to the right of the source text.
How a CAT tool can help you?
As a translator works, the CAT tool builds a database of previous translations for the same source segment, which are displayed for the translator to select from with a single click. This database, known as translation memory, can be used not only for the text you’re currently translating but also for other texts.
