Evolution Is Not Neutral: New Study Challenges 60-Year Biology Theory

New research challenges the long-standing idea that most fixed genetic mutations are neutral. For many years, scientists studying evolution have believed that most genetic changes influencing how genes and proteins evolve are essentially neutral. These mutations were thought to be neither harmful nor helpful, allowing them to pass through natural selection without much notice. A [...]
