Answer 1
The pace of evolution depends on how well adapted a species is to its environment and how stable the environment is. If a species is not well adapted to its environment then it will either evolve or go extinct. If the environment changes then the species living in it will have to adapt and evolve, or go extinct. If a species is well adapted to its environment and the environment is not changing then there will be no evolutionary pressure and no evolutionary process will occur. This kind of stability can be maintained for millions of years sometimes but ultimately every environment will change.
Answer 2
The above is not quite correct. Evolution, the change in allele frequency over time in a population of organisms, never stops. Variation by mutation, independent alignment of chromosomes, crossing over and random fertilization still goes on in species. The selection may be stabilizing if the environment is stable, but alleles change. Evolution and speciation are two things that flow seamlessly one into the other.
Answer 3
The question suggests that the asker is a bit confused about what constitutes a species. For all intents and purposes, we can replace the word 'species' with 'population'. Evolution concerns the changes in allele-frequencies in reproductively linked groups of organisms - populations. 'Species' is just a label that we attach to reproductively linked populations that share definitive features. Species do not become species: they already are, and always have been. Occasionally, we find reason to attach a new species-label to a particular population. Usually such reasons are found in increasing reproductive isolation and the divergence of phenotypes.
No, evolution does not stop once a species has evolved. Evolution is a continuous process driven by natural selection, genetic drift, and other mechanisms that lead to changes in populations over time. As environments change and new selection pressures arise, species may continue to evolve.

What are the 5 types for evolution?
The five types of evolution are divergent evolution (species diverge from a common ancestor), convergent evolution (unrelated species develop similar traits), coevolution (two species evolve in response to each other), parallel evolution (related species independently evolve similar traits), and adaptive radiation (rapid diversification of species to fill ecological niches).
How can the evolution of one species affect the evolution of another?
The evolution of one species can impact another through coevolution, where changes in one species drive adaptations in another. This can lead to mutualism, where both species benefit, or antagonism, where one species may be negatively affected. Interactions such as competition, predation, and symbiosis can all shape the evolution of species over time.
The principle that living species were descend with changes from other species over time is referred to as?
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.
What are the products of evolution?
The products of evolution include the diversity of species, adaptation to environments, and the development of complex biological structures and functions. Evolution also leads to the formation of new species through the process of speciation.
What are examples of structural evidence of evolution?
Examples of structural evidence of evolution include homologous structures, which are similar in form and function but have different evolutionary origins, and vestigial structures, which are remnants of once-functional features that have no purpose in the current species. Another example is the fossil record, which shows transitional forms that demonstrate gradual changes in species over time.
How would you use population and evolution in a sentence together?
Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.
What is a change of a species over time called?
Evolution is a change in species over time.

Evolution and natural selection stop if groups of a species are isolated from each other... true or false?
False. Isolation promotes natural selection of the unique mutations and recombinations in an isolated population, thus leading to evolution.
What is the subject of the book The Edge of Evolution?
The Edge of Evolution: The Search for the Limits of Darwinism is about the evolution and that it can produce changes within species, but there is a limit to the ability of evolution to generate diversity, and this limit (the "edge of evolution") is somewhere between species and orders.
Why hasn't anyone seen a new species appear in biological evolution.?
Evolution doesn't work like that. Since evolution is an ongoing, continuous mechanism, every species that we see is the 'newest' species in its particular line

What is the key component of evolution?
The key component of evolution is reproduction of the species.
What is a sentence using the word evolution?
Evolution has changed many species
What is the evolution of species from an existing species?
Different traits in a organism
When does evolution act?
Evolution is always happening. Species are constantly changing to adapt to their surroundings. If evolution wasn't always happening, many different species would have died.
