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 would be an a homologous structure to a human arm bone?
Arm bones of all mammals . APEX=A bird's wing bone
What are structures that have different functions in different species but develop from the same embryonic tissue?
Homologous structures are anatomical structures that share a common evolutionary origin, but may have different functions in different species. These structures develop from the same embryonic tissue and demonstrate evolutionary relationships between species. An example is the forelimbs of vertebrates, which have different functions such as wings in birds, flippers in whales, and arms in humans.
What are homologous structures between birds and bats?
Birds and bats are homoplasious because they are similar, but not derived from a common ancestor. An example of homologous structures is a man's arm and a cow's foreleg. They are anatomically similar but have different functions.
A birds wings are homologous to an?
A bird's wings are homologous to a human's arms. Both structures share a similar basic skeletal pattern despite their different functions. This indicates a common evolutionary ancestry between birds and humans.
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
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.
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.
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.
Birds and bees have wings are their wings homologous features or analogous features?
The wings of birds and bees are an example of analogous features, as they have evolved independently in each group and do not share a common ancestry that possessed wings. Homologous features are those that are inherited from a common ancestor and are usually more similar in structure.
