One problem with a thick layer of thatch is that newly sown seed will root in the thatch layer â not the soil. Thatch doesn't provide the same insulation as soil, so the roots of such plants dry out quickly, and the lawn dies. A heavily thatched lawn dries out faster so you have to water more frequently.
The field of molecular biology provides the most detailed and convincing evidence available for biological evolution. In its unveiling of the nature of DNA and the workings of organisms at the level of enzymes and other protein molecules, it has shown that these molecules hold information about an organismâs ancestry.
The Proof Is in the Proteins: Test Supports Universal Common Ancestor for All Life. One researcher put the basic biological assumption of a single common ancestor to the test--and found that advanced genetic analysis and sophisticated statistics back up Darwin's age-old proposition.By Katherine Harmon | May 13, 2010.he Proof Is in the Proteins: Test Supports Universal Common Ancestor for All Life.
