The pectoral flippers of fish and wings of bats are within a similar group. Homology is defined as the similarity between organisms and the structures in different animals. This similarity occurs as a result of their evolution from a common ancestor. The connection is regarding the form that the structure takes on, and also the function it performs. Homologous structures are functionally similar, and they formed from a common ancestor.
They are not as focused on the physical features of organisms, but rather, it refers to the conserved genetic sequences and the contradiction observed between different organs that come from the same type of embryonic tissue. Homologous structures are similar in origin, but they are different in function. You can compare the wings of a bat and the fins of a fish. They possess a similar genetic and developmental origin.
The pectoral fins of fish and wings of bats. These animal parts meet the tests of homology. The pectoral fins of fish and wings of bats are shown to have common genetics and origins of development.
They are both modifications of the same anatomical structure, which are the vertebrate limbs. When it comes to the other possible answers, though they are similar, their origins are unique. To fit the tests of homology, they must share the same or similar origin. For example, the wings of birds and bees are similar, but the origin of these animals is individually unique.
The pectoral fins of fish and wings of bats. -pectoral fins and wings meet the tests of homology: they can be shown to have a common genetic and developmental origin. each is a modification of the same basic anatomical structure, the vertebrate limb. the wings of bees and birds, by contrast, are functionally similar, but no more than that. their evolutionary origins are individually unique, and there is no developmental commonality. in no sense do they share a common developmental or evolutionary origin. human and octopus eyes are indeed anatomically similar, but like the other incorrect examples, they are distinct and separate innovations in evolution.
