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.

The legs of a cat and fins of a whale are analogous structures because they have different evolutionary origins but serve a similar function in terms of movement. Homologous structures would be when two species share a common ancestor and have similar structures with different functions.

What appendage does the skeleton of a whales fin resemble?
On the outside, the fins of a whale resemble the fins of a fish, because they have evolved for the same purpose. But when you look at a whale skeleton, the fins look like arms and hands. That's because whales are not fish, they are actually mammals that have evolved from land-dwelling creatures with four legs.
Which set of structures are homologous?
A hydrocarbon that possesses one double bond belongs to the next homologous series called alkenes.
Human arm is homologous with?
the leg of a horse
What is correct about homologous structures?
All insects have some very distinct structures in common. First is bilateral symmetry and three pairs of legs attached to a body with three major parts, the head, thorax and abdomen. All insects have exoskeletons and an open respiratory system as well.
What difference did scientists discover between today's whales and fossils of their ancestors and how does this show whales and animals with four legs probably descended from a common ancestor?
Scientists have discovered that whales' ancestors had vestigial hind limbs, now absent in modern whales. These vestiges are important evidence of a shared ancestry with four-legged land animals. The presence of these anatomical remnants suggests an evolutionary link between modern whales and four-legged animals from a common ancestor.
Are the legs of a cat and the fins of a whale homologous or analogous?
Neither. Homologous structures are similar because two organisms came from a common ancestor. Analogous structures are similar because two unrelated organisms were subjected to similar environments. But the legs of a cat and the fins of a whale are not similar enough to be characterized as either homologous or analogous. The ancestors of whales were hoofed mammals, and one could argue that a hoofed mammal's leg and a cat's leg are homologous. However, after millions of years of being in the oceans, whales' fins have adapted such that they are now not at all similar to the legs of a cat.
Have all mammals got four legs?
No. If you look at a whale, it is a mammal but it has a tail and fins and a monkey has 2 arms and 2 legs scientifically classified.

Does a bird have fins?
Turtles are water-dwelling reptiles, so they have webbed feet but they do not have fins like a fish or dolphin.
Give an example of evolution as a remodeling process?
Whale fins remodeled from the legs of a ground dwelling animal over some millions of years. The bones are of the same construction and number, just overlaid with flippers now.
