Are the wings of birds and dragonflies homologous structures?

Are the wings of birds and dragonflies homologous structures?

Now, consider the wings of butterflies and dragonflies. These organisms both evolved from a common ancestor, an ancient flying insect. The wings both share similar structural features. When organisms share similar characteristics along with a common ancestor, we say that their characteristics are homologous structures.

What is the wing structure of a dragonfly?

The wings of dragonflies are mainly composed of veins and membranes, a typical nanocomposite material. The veins and membranes have a complex design within the wing that give rise to whole-wing characteristics which result in dragonflies being supremely versatile, maneuverable fliers.

How are bird wings and insect wings alike?

Insects have two pairs of wings, while bats and birds each have one pair. Insect wings lack bones, but bird and bat wings have them. Butterfly wings are covered in scales, bird wings in feathers, and bat wings with bare skin.

Which structures are similar in function but do not indicate that the organisms are related?

Analogous structures are similar in function but not structure. Analogous structures are not the result of common descent.

How do you describe dragonfly wings?

Dragonflies have long, delicate, membranous wings which are transparent and some have light yellow colouring near the tips. Their bodies are long and slender and they have a short antennae. Dragonflies are very colourful, for example the Green Darner Dargonfly has a green thorax and a blue segmented abdomen.

Are bird wings homologous to bee wings?

These are called analogous structures. Analogous structures: The (c) wing of a honeybee is similar in shape to a (b) bird wing and (a) bat wing, and it serves the same function. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous, but not homologous.
