To begin, we have a butterfly, a bird, and a bat. The structure of these organisms are similar, but in unrelated ways.
To learn more about the topic of evolution, we are using three different organisms to understand analogous structures.
Our goal is to use evidence, like analogous structures, to better understand the study of evolution.

Just by looking at them, we can see some of the things they have in common.
From prior knowledge, we know all three of these organisms can fly.
Their bone structures are similar because they evolved to do the same job.
Even though the organisms have similar structures, they did not inherit them from a common ancestor.
These organisms independently evolved, but have the same purpose.
Analogous structures are pieces of evidence for evolution. They are proof of the theory of natural selection, and that organisms had a number of adaptations over time.
