2. Describe the following structures, and give an example of each: a. Homologous structure-
b. Analogous structure-
c. Vestigial structure-

Homologous structures are similar bone structures in very different species, like whales and bats. We use this to see how we evolved alongside other animals with the same common ancestor.

Analogous organs are those organs which have the different embryonic origin but perform the similar function. For example, wings of a bird and wings of the insect. Wings of bird are modified forelimbs while wings of an insect thin membranous expansion of exoskeleton. Analogous organs are formed due to convergent evolution.

Vestigial structures are structures we don't need anymore, like our tailbone. We can use these to tell how our ancestors lived and what they needed to survive.
