1.   It follows that some process other than random mutation and selection must be involved.

2.   Our random mutation is essential because it is unnecessary.

3.   The genes that cause the elaborate ornament or long tail to appear are subject to random mutation.

4.   When they seemed to resemble each other rather too closely, he introduced random mutations in the offspring.

5.   Through random mutations, nature constantly tests new genetic models of organisms.

6.   We want them to emerge solely as a result of cumulative selection of random mutations.

7.   As with mitochondrial DNA, plotting these random mutations yields a tree with the oldest mutation at the trunk and younger mutations forming successive branches.

8.   Bacteria can develop resistance to drugs they are frequently exposed to, by random mutations some of which allow the microbes to survive.

9.   Chromosomes experience random mutations, and their ends fray.
