Gradual changes across generations, driven by processes like natural selection and genetic drift, influence organisms by allowing them to adapt to shifting environments and ecological niches. These incremental adaptations can lead to the development of new traits that enhance survival and reproductive success. Over time, such changes contribute to the diversity of species, as populations diverge and evolve in response to their specific habitats and challenges. Ultimately, this gradual evolution shapes the Biology and behavior of organisms, ensuring their continued existence in a dynamic world.

Natural selection varies the death rates of individuals in the current generation. As the next generation is born with different traits derived from parents that were survivors of the current generation, the population changes gradually from generation to generation better able to survive longer against the natural selection pressures. Should selection pressures change in the future (and they very likely will) the direction of changes caused by natural selection will also change (with a corresponding but temporary increase in death rates if the change is large and sudden).
The theory that explains how organisms change due to adaptations that help them survive and reproduce is known as the theory of evolution by natural selection, proposed by Charles Darwin. This theory suggests that individuals with advantageous traits are more likely to survive and pass on their genes to the next generation, leading to gradual changes in the population over time.
A gradual change in the kinds of organisms living in an ecosystem, typically in response to environmental factors, is known as ecological succession. This process involves a series of stages that ultimately lead to a stable community of plants and animals in the ecosystem.

Evolution is the process by which species of organisms change over time through the gradual accumulation of genetic variations that are passed down from generation to generation, leading to the development of new traits and the emergence of different species.

Scientists describe evolution as the process by which organisms change over time through the gradual accumulation of small genetic variations. This can lead to the formation of new species and the diversity of life on Earth. Evolution is driven by natural selection, genetic drift, mutation, and other mechanisms that influence how traits are passed on from one generation to the next.

This is known as evolution. Evolution is the gradual change in the heritable characteristics of biological populations over successive generations due to factors such as natural selection, genetic drift, and mutations. It occurs in response to changes in the environment and can result in the adaptation of organisms to better survive and reproduce in their environment.
The theory that explains how organisms change due to adaptations that help them survive and reproduce is known as the theory of evolution by natural selection, proposed by Charles Darwin. This theory suggests that individuals with advantageous traits are more likely to survive and pass on their genes to the next generation, leading to gradual changes in the population over time.

The gradual change and buildup of organisms in an environment is known as ecological succession. It involves the sequential process of species replacing one another over time in response to changing environmental conditions. This process typically starts with pioneer species and ends with a stable community.
