Evidence of Evolution/Natural Selectoin

The moth wing and the bat wing are example of structures.

(a)  

• Analogous
• Homologous
• Vestigial
• Fossil

When comparing the DNA of two different organisms, the more differences in the DNA base pairs the more-

• Closely related they are.

• Distantly related they are.

• It doesn't prove anything.

• They look alike.

Vestigial structures

• structures that perform a similar function but are not similar in origin

• remnants of once-important structures that have slowly lost all or most of their function

• features found in different organisms that share structural similarities but may have very different functions

• preserved remains of an organism
