11.   Other attributes include an ability to respond to environmental changes without human intervention or evolve through selecting the best results from random mutation.

12.   Random genetic mutations, sifted by natural selection, give rise to biological order.

13.   Random mutations produce new genes, with successful genes flourishing and ineffective ones quickly dying off.

14.   The differences in DNA from the Y chromosome, on the other hand, were minor and probably arose from random mutation, the researchers say.

15.   The genetic changes, caused by random mutations and by the differing combinations of parental genes passed along to offspring, give some individuals an advantage over others.

16.   Theoretically, such a random mutation could strike anyone.

17.   People who carry genetically crippled HIV that arose through random mutations do not seem to get sick.

18.   Chances are, everyone with HIV carries a virus with a random mutation that makes it capable of resisting whatever drug comes along.

19.   He said the next step is to re-engineer the virus, putting the extra gene in a spot that is less likely to be dropped through random mutation.

20.   Most Cohanim had the same version of the Y chromosome or close variants that differ because of random mutations.
