Out of homologous, vestigial,and analogous structures which can show common ancestry among organisms? low does the fossil record support the theory of evolution?

## Step 1<br />The question is asking about the types of structures that can show common ancestry among organisms. The options provided are homologous, vestigial, and analogous structures.<br /><br />## Step 2<br />Homologous structures are those that have a similar structure but may perform different functions. They indicate a common ancestry because they suggest that the organisms sharing these structures have evolved from a common ancestor.<br /><br />## Step 3<br />Vestigial structures are remnants of organs or structures that had a function in an early ancestor. They do not necessarily indicate common ancestry, but rather indicate that the organism has evolved over time.<br /><br />## Step 4<br />Analogous structures are those that perform the same function but have different structures. They do not indicate common ancestry, but rather indicate that the organisms have adapted to similar environments.<br /><br />## Step 5<br />The second part of the question asks how the fossil record supports the theory of evolution. The fossil record provides evidence of the existence of species that no longer exist, showing a progression of life forms over time. This supports the theory of evolution, which posits that species have evolved over time.
