Adaptations increase fitness from "summary" of The Origin of Species (Deluxe Library Binding) (Annotated) by Charles Darwin
Adaptations are beneficial traits that increase an organism's chances of survival and reproduction in a particular environment. These adaptations are the result of natural selection, where individuals with advantageous traits are more likely to pass on their genes to the next generation. Over time, these advantageous traits become more common in the population, leading to an increase in fitness. Fitness, in the context of evolution, refers to an organism's ability to survive and reproduce in its environment. Adaptations that increase an organism's fitness can take many forms, from physical characteristics like camouflage or sharp claws to behavioral traits like hunting strategies or mating displays. These adaptations allow organisms to better compete for resources, avoid predators, and attract mates, ultimately leading to greater reproductive success. The process of natural selection ensures that only the fittest individuals survive and reproduce, passing on their advantageous traits to their offspring. This continuous cycle of adaptation and selection drives the evolution of...
