What structures are similar in arrangement?Both provide evidence for evolution.. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. ... . Analogous structures are structures that are similar in unrelated organisms.. What are structures that have a common function and suggest common ancestry?Homologous structures are structures that have a common function and suggest common ancestry. For example, homologous structures include the limbs of mammals, such as bats, lions, whales, and humans, which all have a common ancestor. Different mammals may use their limbs for walking, running, swimming or flying.
What are structures that are similar due to a common environment?Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.
What are structures that do not have a common evolutionary origin but are similar and function?Those structures that do not have a common evolutionary origin but are similar in form or function are called analogous structures. Analogous structures are used for similar purposes in different. This type of evolution is also called convergent evolution. For example, the wings of birds and insects.
