What is the forelimb of a bat?
The order Chiroptera, comprising all bats, has evolved the unique mammalian adaptation of flight. Bat wings are modified tetrapod forelimbs. Because bats are mammals, the skeletal structures in their wings are morphologically homologous to the skeletal components found in other tetrapod forelimbs.
What are the similarities between the forelimbs of the whale human bat and cat?
This is known as homologous structure. human arms, cat forelegs, whale flippers, and bat wings all have the same basic bone structure. While the function of each of these is different, they are all variations of a common ancestor, that has simply adapted to different functions.
How are bat wings and human hands similar?
If you look at the skeletal structure of a bat’s wing, it is almost identical to that of a human hand and arm, only elongated and much, much smaller. Bats also have a thin membrane of elastic-like skin that stretches across the fingers to form the wing.
What do humans cats whales and bats have in common?
An example of homologous structures are the limbs of humans, cats, whales, and bats. They have completely different bone structure, but their wings share the same function, allowing the animal to take flight.
Can dolphins see your skeleton?
It is well known that dolphins can see inside the bodies of their fellow dolphins, and other animals in the water. This is because dolphin sonar evolved to pass through water and does not reflect until it hits something like bone or air sacs.
How are the forelimbs of a bat and a whale different?
For instances, the flippers of a whale, a bat’s wing, forelimb of a horse, a bird’s wing and forelimbs of human are structurally as well as functionally different. Whale’s flippers help in swimming, wings of birds and bat are used in flying, horse’s forelimb help in running and human’s hand is meant for grasping.
What kind of forelimb does a bat have?
Forelimb in bat is modified for flying. Highly elongated metacarpals and phalanges support the skin of wing. Elephant’s forelimb appears like a cylindrical pillar but it is made of same sets of bones.
Why are the forelimbs of all animals the same?
However, anatomically they have similar bones, humerus in the upper arm, radius ulna in the forearm, carpals and metacarpals in the wrist and hand. The presence of homologous organs in different groups of animals indicates their common origin or ancestry and degree of closeness to the difference among various groups.
Are the forelimbs of Man, Cat and bat homologous?
The forelimbs of man, cat, bat and whale are homologous organs. Organs, which have a common fundamental anatomical plan and similar embryonic origin whatever varied functions they may perform are regarded as homologous organs.

How are human, bird, and bat forearm bones alike?
These organisms share the same forearm bones because they all evolved from a common ancestor. Human, bird, and bat forearm bones include the humerus, ulna, radius, carpals, metacarpals, and phalanges. Can you identify these bones on the diagram below?
