Evolution just broke its own logic, a new biology rule may follow
Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...
Genes that don't themselves directly affect the inherited characteristics of an organism but leave them increasingly open to variation may be a significant driving force of evolution, say scientists.
In the children’s game telephone, a whispered phrase like “I ate a pear” can quickly become “I hate bears” as it moves down a line of players. As genes are passed down from parents to offspring, they ...
