The wings of a butterfly and the wings of a bird are analogous, but not homologous. However, their appearance and function are quite similar. How are butterfly and bird wings different? Some organisms may be very closely related, even though a minor genetic change caused a major morphological difference to make them look quite different. The wings of a bird and the wings of a butterfly are: a) analogous structures b) . Genetically, a bat wing and a bird wing have very little in common; the last common ancestor of bats and birds did not have wings like either bats or birds. g: See answer (1) Best Answer.

The Case of Analogous Structures A bat wing and a bee wing are two excellent examples of structures that are structurally similar but not identical. Birds are vertebrates. VESTIGIAL STRUCTURES Gradual changes have occurred through time that have in some cases reduced or removed the function of some body structures and organs. Scientists must determine which type of similarity a feature exhibits to decipher the organisms phylogeny. Thus, lizards, rabbits, and humans all belong to the clade Amniota. The cookie is used to store the user consent for the cookies in the category "Analytics". Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. Ultimately, the coupled use of both morphologic and molecular information is more effective in determining phylogeny. A characteristic is considered a shared-ancestral character if it is found in the ancestor of a group and all of the organisms in the taxon or clade have that trait. What amount of charge will flow through the resistor? Homologous structures: Bat and bird wings are homologous structures, indicating that bats and birds share a common evolutionary past. What type of tissue is it? Instead, these structures are related to one another because they perform the same function. Why are the wing of a bee and the wing of a bird considered analogous structures? Homologous structures refer to two or more structures found in different species that originated from a common ancestor. These are called analogous structures (). Breeders use___to enhance desired traits in domesticated plants and animals. The wings of butterflies are made of semitransparent, tough scales. Homologous Organ: Organs which have different functions but similar structure and origin. 9. Do bats and butterflies have a common ancestor? A specific protein in yeast also found in thesus monkeys.
