Observable changes in organisms over time, such as changes in physical traits or behaviors, provide evidence for evolution by natural selection. These changes illustrate how species can adapt to their environment through genetic variation and selection pressures, leading to the evolution of new species over long periods of time. By studying observable changes, scientists can better understand the mechanisms driving evolution.
The principle that living species descend with changes from other species over time is referred to as evolution. This idea was proposed by Charles Darwin in his theory of evolution by means of natural selection.
The evolution of a species is influenced by factors such as natural selection, genetic variation, environmental changes, and reproductive success. These factors can lead to adaptations that help a species survive and thrive in its environment over time.
Gradual changes in species over time is known as evolution. This is a process where populations of organisms change over generations as a result of genetic variation, natural selection, and adaptations to their environment. Over time, these changes can lead to the formation of new species.
Evolution of a species involves changes in inherited traits over generations, driven by factors like genetic mutations, natural selection, genetic drift, and gene flow. These changes can result in the development of new species from a common ancestor through processes like speciation.

We call this speciation, and is largely driven by evolution and natural selection.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.

Evolution is enabled by natural selection: the ability of a species through its individuals to make long-term improved changes in its response to its environment through beneficial mutations, resulting in the species being able to reproduce itself more successfully than before.

A new and better adapted species.

Yes, evolution is closely related to DNA. Changes in DNA, such as mutations, are the raw material for evolution by natural selection. Over time, these changes can accumulate and lead to the development of new species through the process of evolution.
