feathers
Birds have brains, a chest and wings. Much of their internal body parts are similar to humans including a heart and digestive system.
The wings of bats and birds have a similar function of flight but developed differently, with bat wings being elongated fingers covered in a thin membrane while bird wings are modified forelimbs covered in feathers. Additionally, the eyes of cephalopods (e.g. squid) and vertebrates both function in vision, but cephalopod eyes developed independently and have a different structure.
Analogous structures are body parts that have a similar function in different species but have evolved separately, thus not sharing a common ancestor. These structures result from convergent evolution, where organisms adapt to similar environmental pressures.
That depends on what two species you're referring to. Homologous parts are similar in structure and evolutionary origin, though not necessarily in function. for example: human arms and bat's wings Analogous parts, on the other hand function similarly, but may not be similar in structure or evolutionary origin. example: a butterfly's wings and birds' wings
Analogous structures are body parts or organs in different species that have a similar function but not necessarily a common evolutionary origin. For example, the wings of birds and bats are analogous structures because they both serve the purpose of flight, even though they evolved independently.
Darwin noticed that birds of the same species had developed different beaks over time when they were isolated into different sections of the island. The different beaks helped each bird eat more depending on the diet of that specific bird.
The function of a cow's heart is the same as a human heart - to circulate blood throughout the body. The cow's heart is very similar to a human heart in structure.
