Question

what function does the limb serve in each animal? how are the limb bones of the four animals similar? based on these similarities what can be inferred about the evolution of the four animals. Its a picture of a human hand, a dogs paw, a birds wing, an a whales fine. PLEASE hurryyyy

Answer 1

The correct answer to this question is this one:

The function of the limb serve to the four animals is that it supports the backbone. These four animals are all vertebrates. This means that they have backbones that supported their whole body posture.
Hope this helps answer your question and have a nice day ahead.

Answer 2

Answer:

The humans use this limb to grab things, body language, and sign language.

The dogs use this limb for all kinds of weight-bearing activities like walking, jumping, running et cetera.

Birds use this to fly and whales use it as flapper.

The limbs of all these four animals are the example of homologous organs that is, they all are similar in structure but adapted to perform different functions during the course of evolution.

For example, in all four organisms, the limb is made up of the same set of bones such as humerus, radius, ulna, carpals, metacarpals, and phalanges.

Homology in structure shows that they must have evolved from a common ancestor and diverge to perform different functions as an adaptation to the contrasting environment.
