What does it mean when an evolutionary change increases fitness?
Evolutionary change that increases fitness means that a population of organisms has become better adapted to its environment. This can happen in a number of ways, such as through the development of new traits or the loss of old traits.
When an evolutionary change increases fitness, it means that the organisms that have the new trait are more likely to survive and reproduce than those that do not. This can lead to a change in the genetic makeup of the population over time.
There are many examples of evolutionary changes that have increased fitness. For example, the development of antibiotic resistance in bacteria has allowed them to survive in environments that would have previously killed them. The development of flight in birds has allowed them to escape predators and find new sources of food.
Evolutionary change that increases fitness is essential for the survival of species. It allows populations to adapt to changing environments and to compete with other species.
