The modern evolutionary synthesis leaves unresolved some of the most fundamental, long-standing questions in evolutionary biology: What is the role of sex in evolution? How does complex adaptation evolve? How can selection operate effectively on genetic interactions? More recently, the molecular biology and genomics revolutions have raised a host of critical new questions, through empirical findings that the modern synthesis fails to explain: for example, the discovery of de novo<span> genes; the immense constructive role of transposable elements in evolution; genetic variance and biochemical activity that go far beyond what traditional natural selection can maintain; perplexing cases of molecular parallelism; and more.</span>

The answer is a relapse. A relapse occurs when a person who has gone into recovery or has been sober for a long time goes back into abusing drugs and any addictive substances. This can also be seen in patients who had shown a period of health improvement goes back to deteriorating state.
