What type of evidence is the forelimbs of flightless birds?
An homologous structure
What is a homologous structure?
A structure with similar shape but a different use
Which type of anatomic structure are birds wings and human arms when compared to each other?
Homologous
What is homologous structures?
A structure with similar shape but a different use
What are the difference between homologous organ and analogous organ?
Homologous organs have similar embryonic origin and basic structure whereas Analogous organs have different embryonic origin and basic structure. Homologous organs may look different and may perform different function; e.g., forelimb of a man and flipper of a whale. Whereas Analogous organs look alike and perform same functions; e.g., Wings of birds and insects.
What are homologous structures between birds and bats?
Wings in both birds and bats are considered homologous structures. They have a similar function (flight) but different evolutionary origins – birds have wings made of feathers while bats have wings made of skin stretched between elongated finger bones.
What is the relationship between homologous structure and analogous structure?
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.
A birds wings are homologous to an?
Alligators claw
How can a bats wing be considered a homologous structure and an analogous?
They are homologous in the sense that all tetrapods share that forelimb structure. They are analogous because both bats and birds adapted flight to their local environmental conditions. One being a mammal, that has the finger extension type wing and one being aves with the full forelimb extending the wing. They have the flight in common, but not the structures, so are analogous. They have an ancestral condition leading to the similarity of forelimb structure and so are homologous.
An example of a homologous structure?
Examples of Homologous Structure: Rodent teeth Hooves in species of camels, goats, sheep and cattle Hands and feet in primates Bird feathers Shark morphology
Are the mouthparts of the two species homologous or analogous?
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
Do birds have a neocortex?
They do not have the mammalian neocortex, but they have homologous structures that function in a similar manner.
