How is the human forelimb similar to cat whale and bat forelimbs?

How is the human forelimb similar to cat whale and bat forelimbs?

Analogous organs are a result of convergent evolution. We can say that similar habitat has resulted in selection of similar adaptive features in different groups of organisms but towards the same function. Homologous organs – Forelimbs of man, cat, bat and whale are homologous organs.

Why do the human cat whale and bat have such similar front limbs?

Explanation: All the fore limbs that you mention are made up of same sets of bones. These vertebrates are all mammals, hence evolved from a common ancestral stock. So they all inherited a basic anatomical structure which later became adapted for different habits and habitats.

Why are all mammals forelimbs homologous?

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. The forelimbs of all mammals have the same basic bone structure. Analogous structures are structures that are similar in unrelated organisms.

Why are the forelimbs of bats and birds considered to be homologous structures?

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.

How do cats use their forelimbs?

Cats’ forelimbs are designed for speed, power, and acceleration rather than for stamina; they maintain all five metacarpals and phalanges, although the first digit is relatively small.

How are the forelimbs different?

How are the forelimbs different? The two forelimbs shown are different because the bat’s “finger bones” are expanded and form the structure of a wing, while the human’s phalanges are shorter and form the structure of what we know as fingers.

How are bats forelimbs different from other mammals forelimbs?

The forelimbs of a bat are different from other mammals as they are modified into wings for the purpose of flying.

Are bat wings and whale flipper homologous?

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.

What is the function of a whale forelimb?

The dog’s forelimb role is to assist with the motion. Whale forelimbs act like flippers and help the Whale to swim easily. Dog forelimbs, Human arms, and whales forelimbs are homologous organs.

What are the function of forelimbs?

Their main function is thought to be associated with providing body support during sitting or walking, and/or the absorption of impact forces during landing (Nauwelaerts & Aerts, 2006). Frog forelimbs are typically short as the hind limbs are the principal limb pair generating propulsion.

Are forelimbs homologous?

All vertebrate forelimbs are homologous, meaning that they all evolved from the same structures. For example, the flipper of a turtle or of a dolphin, the arm of a human, the foreleg of a horse, and the wings of both bats and birds are ultimately homologous, despite the large differences between them.

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.

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.

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 bat forelimbs different from human fingers?

The two forelimbs shown are different because the bat’s “finger bones” are expanded and form the structure of a wing, while the human’s phalanges are shorter and form the structure of what we know as fingers. Keeping this in view, what are examples of homologous structures and how are they evidence of evolution?

How are the bones of a human arm similar to a bat’s?

But under the surface, they ARE similar. Look at the figure below. The bones of a human arm are similar in structure and order to the bones in the front limbs of a cat, a dolphin, and a bat. These similarities suggest that cats, whales, bats, and humans had a common ancestor.
