Among, say, mammals they are homologous, but the wing of an insect and a bat are analogous.

How are analogous and homologous structures different?

They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.


What are five types of homologies that provide evidence of common ancestry?

limbs wings legs arms and flippers


Compare a bird wing to a butterfly wing What kind of structure does this pair represent?

No they are not. Homologus structures are structures that originated from a common ancestor, they show similarity in anatomy and development even tho they may have different functions. For example the human arm and bird wing are homologus (pentadactyl limb).Bird and insect wings are ANALOGUS, which means they show similar function but show no similar structural relationship.


How does the existence of homologous structures support the theory of evolution?

When comparing earlier and later developments, homologous structures become more refined through time. When comparing common ancestors, we can compare the derivations of a homologous structure between two successors and also between the ancestor and each successor. We thus see several relationships between this and that, from 'right now', 'a little before now' and 'way back then'. For example, we see two species whose legs are very similarly structured, and then we find an ancestor that also possessed such a leg, except it was simpler or shorter or in a different ratio between sections. We can draw conclusions that the later species developed both from this earlier one, and that this earlier one died out, after its successors (which eventually became the newer species) could survive more often because they had better structured legs.

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.


Two species have homologous structures what do these homologous strcutures show about the evolutionary relationship between the two species?

The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.


What structure describes scientists believe human arms and whale flippers were inherited from a common ancestor?

Homologous add Perhaps to a human's foot.


What is a sentence using the word homologous?

The homologous is the study of animals.


What are structures that develop from the same embryonic tissues but have different mature forms?

Homologous structures develop from the same embryonic tissue but mature into different forms in different species. An example is the pentadactyl limb in vertebrates, where the same bones form the wings of a bat, flippers of a whale, and arms of a human.


What is the difference between homologous structures and analogous structures?

Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)


How are analogous and homologous structures different?

They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.


An example of a homologous structure?

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.


Is a bat wing and a mouse arm a homologous structure?

No, a bat wing and a mouse arm are not homologous structures. Homologous structures are similar body parts that are derived from a common ancestor, while bat wings and mouse arms have different evolutionary origins and serve different functions.


Are arms paws and tails homologous structures?

yes


What do arms wings legs and flippers have in common?

They are all appendages used for movement and manipulation in animals. Arms and wings are typically used for flying or reaching, legs are used for walking or running, and flippers are used for swimming.
