The process of forming new species from preexisting species is called speciation. It typically occurs when populations of a species become reproductively isolated from one another, leading to genetic divergence and the eventual evolution of distinct species. Speciation can happen through various mechanisms, such as geographic isolation, behavioral differences, or genetic mutations.
The gradual development of new organisms from preexisting organisms is called evolution. This process involves genetic changes and adaptations over generations that result in the diversity of life on Earth.
The process of species changing over time is called evolution. This process involves genetic variations within populations, natural selection, and adaptation to changing environments.
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
Darwin's theory of descent with modification, also known as evolution by natural selection, proposes that species evolve over time through the process of variation and differential survival and reproduction. This means that species descend from common ancestors and accumulate changes or modifications that help them adapt to their environment.
Natural selection is a key mechanism in evolution where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this process leads to the gradual change and adaptation of species to their environment, resulting in the evolution of new species.
Evolution
The gradual development of new organisms from preexisting organisms is called evolution. This process involves genetic changes and adaptations over generations that result in the diversity of life on Earth.
Natural selection causes those organisms that are better suited to survive and reproduce to pass on their genes to future generations, causing their children to be better suited to their environment as well. Over time, these traits that have been selected by natural selection will result in an overall change in a species.

The process is called "adaptation."
The process of species changing over time is called evolution. This process involves genetic variations within populations, natural selection, and adaptation to changing environments.
Biological evolution is the change of animal and plant life over time. Biological evolution is used to explain changes in finch beaks for example.
