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.

What is the difference between macro evolution and micro evolution?
The difference is one of scale and scope. This is best explained using a single species and its descendants as an example:Every change that happens to the species up to the point of speciation would be classified as "micro-evolution". But after speciation, divergence would not stop: the two new species would continue to diverge from one another, possibly resulting in yet more branching events, more new species. The scope would increase to include all of those as well. At this scale, we're talking about "macro-evolution". When we zoom in on one of those newly emerged species, we can see that the resulting "macro-evolution" is still being generated by the cumulative effects of "micro-evolution" within each individual population.
What is the gradual change in the types of species that live in a community.?
ecological succession
What is the gradual development of new organisms from preexisting organisms called?
I believe you are referring to evolution, which occurs as a result of natural selection causing species to change into new species over time.
Evolution that leads to similarities in different species?
Convergent:)
The gradual change in a species over time is what?
evolution
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.
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 a sentence using the word evolution?
Evolution has changed many species
What is the key component of evolution?
The key component of evolution is reproduction of the 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.
What are the divisions of evolution?
Evolution is sometimes described as macro-evolution, which is the long-term evolution of an entire new species, and micro-evolution, which is largely to do with less significant evolutionary changes within a species. Many creationists accept the existence of micro-evolution, but say that macro-evolution does not occur.
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.
True or false the theory of evolution focuses on the evolution of the human species?
False. Evolution is a general theory relating to the change amongst species over time. It is not specific to any particular species, nor even to a group of species, but to all species that have ever existed, are existing and will ever exist.
