Evolution is constant from "summary" of Adapt by Tim Harford
Evolution is constant. It's not a one-time event that happened in the distant past. It's an ongoing process, happening all around us, all the time. Every living thing is constantly changing and adapting to its environment. And the pace of change is accelerating. With each passing generation, new traits emerge, old ones disappear, and the genetic makeup of a species evolves. This constant evolution is driven by several factors. One of the most important is natural selection. The individuals within a population that are best suited to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. Over time, these traits become more common in the population, leading to the evolution of new species. But natural selection is not the only force at work. Random mutations also play a crucial role in driving evolution. These genetic changes can be beneficial, harmful, or neutral. Beneficial mutations increase an organism's chances of survival and reproduction, while harmful mutations decrease those chances. Neutral mutations have no effect on an orga...
