Arm bones of all mammals . APEX=A bird's wing bone
A homologous structure to a human arm bone would be the forelimb bones in other mammals, such as the forelimb bones in a bat or a whale. These structures may have different functions (e.g. for flying or swimming), but they share a common evolutionary origin with the human arm bones.
Analogous means that the structures have different origins, but they do the same things. Homologous means the opposite: that they have the same origins but are adapted to do different functions.
An example of an analogous structure is the wings of birds and the wings of bats. Both structures have a similar function (flying) but are made of different materials and have evolved separately in these two distinct groups of animals.
The humerus in a bat serves as the main bone in the wing, providing support and attachment for muscles that allow for flight. It also helps in maneuvering and controlling the bat's wing movements during flight.

Homologous structures refer to structures on different species that are similar in function and their evolutionary origin. Analogous structures are similar in function but do not share a similarity in evolutionary origin.
Bat's wings are the equivalent of the human arm. The bats fingers are highly elongated to produce the wing tip as well as support for the wing's membrane. The forearm provides wing length on the far side of the elbow that can be folded back against the upper arm (humerus) when they are at rest.
Homologous means similar to but not the same thing, as a squirrel's foreleg is homologous to a human's arm.
Not all animals have the same skeletal structure. Whales have bones in their "flippers" that resemble the same bones that make up the human "arm". This is called a homologous structure.
Evolution is the process of deriving species from other species, forms from other forms. Homologous structures are structures in organisms that share the same components. A good example is the vertebrate limb - it's clear that our arm, a bat's wing, a dolphin's flipper and a mole's digging paw all share the same identifiable bones. This supports the idea they're all derived from a structure in a common ancestor, as opposed to being created independently.
An arm is an analogous feature because it has evolved independently in different species to serve a similar function, like in the wings of birds and bats. It is not homologous, as it does not share a common evolutionary origin, like the forelimbs of vertebrates. An arm is not vestigial, as it is a functional and adaptive trait that has been retained through evolution for various purposes.
Homologous structures are features with a similar anatomical origin but have different functions, indicating common ancestry, such as the limbs of vertebrates. Analogous structures have similar functions but different anatomical origins, suggesting they evolved independently due to similar environmental pressures, like the wings of birds and insects.
