Is a whale fin a homologous structure?

Is a whale fin a homologous structure?

We can first look at the homologous structures in whales. One major homolgous structure is the fin of a whale. This is evidence that whales, as mammals, share a common ancestor with other mammals. Another example of a homologous structure in whales is their inner ear bones.

Are our limbs homologous or analogous to whales?

Whales, lizards, humans, and birds all have the same basic limb layout. But how did such different animals wind up with the same sort of limb? The answer is that they inherited it from a common ancestor, just as cousins might inherit the same trait from their grandfather.

Which structure of a whale is homologous to your leg?

In the whale flipper, the bones are very short and thick. Bat and bird wings, the front leg of a horse, the flipper of a whale, and the arm of a human are homologous structures. This shows that bats, birds, horses, whales, and people have a shared past in how they changed over time.

Are whale flippers homologous?

What are homologous structures? The human hand and the blue whale flipper are homologous structures. Homologous structures are structures (such as bones or organs) that are found in animals of different species.

Is human arm and whale flipper homologous?

Homologous structures share a similar embryonic origin. For example, the bones in a whale’s front flipper are homologous to the bones in the human arm. These structures are not analogous. A butterfly or bird’s wings are analogous but not homologous.

Is the wing of a bat homologous to a whale?

Homologous. Almost bone for bone. They are both tetrapods and mammals. The wing of a bird and the wing of a bat are analogous. They are tetrapods, but one is a bird and one is a mammal. Are the legs of a cat and the fins of a whale homologous? Yes they are. I disagree.

Is the flipper of a whale the same as a human arm?

The flipper of a whale, the wing of a bat, and the leg of a cat are all very similar to the human arm, with a large upper “arm” bone (the humerus in humans) and a lower part made of two bones, a larger bone on one side (the radius in humans) and a smaller bone on the other side (the ulna).

Which is an example of a homologous structure?

Meaning that, despite their outward differences, animals with homologous structures are somehow related. Here are some examples of homologous structures that humans share with other creatures from the animal kingdom. A dolphin’s flipper, a bird’s wing, a cat’s leg, and a human arm are considered homologous structures.

How are the legs of a horse similar?

In some cases, those parts are similar in structure, function or both. For example, the bones in the legs of a horse and donkey are similar in both structure and function. Both animals use them primarily for walking and running.
