Analogous structures are features of two different species that are similar in how the function, but the structure of the two features is different. The wings of an insect and the wings of a bird are analogous structures.
Rhizoids in molds are analogous to roots in plants. They both serve as structures that anchor the organism in place and aid in absorbing nutrients from the environment.
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
Homologous structures and analogous structures both relate to the study of comparative anatomy and evolution. They demonstrate how different species can develop similar features in response to environmental pressures or evolutionary paths. While homologous structures arise from a common ancestor and share a similar developmental origin, analogous structures serve similar functions but do not share a common evolutionary origin. Both types of structures provide insight into evolutionary relationships and adaptations among species.
Analogous structures can be replaced or modified through the process of evolution by natural selection. As organisms adapt to different environments, structures that are homologous may evolve to serve different functions. Over time, mutations and selective pressures can lead to the modification or replacement of analogous structures in different species to better suit their specific needs.
Analogous regions in plants refer to structures that have similar functions but evolved independently in different plant lineages. For example, the wings of a maple seed and a dandelion seed are analogous structures that evolved to aid in wind dispersal, even though they come from different plant families.
Similar structures that evolved independently are called analogous structures, or analogies.

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.

Yes, homologous structures have common bone and muscle structures suggesting that they came from an common ancestor while analogous structures do not share any similarity in features, suggesting that they derived from two separate origins.
Similar structures that evolved independently are called convergent evolution. This occurs when different species adapt to similar environmental pressures and develop analogous traits, even though they do not share a common ancestor that had those traits.

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.
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.
