E MULTIPLE-CHOICE QUESTION What do cat legs and whale flippers (shown in the top of the chart) have in common? Analogous Structures Homologous Structures

## Step 1<br />The problem is asking us to identify the type of structures that cat legs and whale flippers have in common. The options provided are analogous structures and homologous structures.<br /><br />## Step 2<br />Analogous structures are those that perform a similar function but are not derived from a common ancestor. They are the result of convergent evolution, where different species independently evolve similar traits as they adapt to similar environments or ecological niches.<br /><br />## Step 3<br />On the other hand, homologous structures are those that are derived from a common ancestor. They may not perform the same function in the different species, but they share a common origin.<br /><br />## Step 4<br />In the case of cat legs and whale flippers, they are both derived from the same ancestral limb structure though they perform different functions in the two species. This makes them homologous structures.
