The short, simple, answer, is survival. The environment is one of the things that drive evolution. When a species is suited to the environment in which it lives it remains relatively stable in it's particular form and exhibits little change.
If the environment becomes unstable or is radically changed in some way, such as ever more cooling temperatures, or a depletion in some natural resource, this drives a species to adapt to the new environment through change/evolution. Depending on the speed with which an environment can change, or the severity of the change in the environment, the pace of the evolution can be relatively slow or relatively fast, but in geologic terms, either fast or slow evolutionarily speaking, the change is still slow in human terms. Evolution always takes usually several millennia, and on rare occasions, based on the scope of the environmental changes, it can happen in as little as several centuries, but this is the exception and not the rule.
What else can I help you with?
The result of different organisms becoming adapted to different environments?
The result is increased survival and reproduction in their specific environment due to better fitness and ability to meet the challenges they face. Over time, this adaptation can lead to speciation as populations evolve unique traits suited to their environment, ultimately leading to biodiversity.
How do populations evolve over time?
Populations evolve over time through the process of natural selection, genetic drift, gene flow, and mutations. These mechanisms can lead to changes in the genetic makeup of a population, resulting in adaptations that increase the population's fitness and survival in its environment.
Does evolution stop once a species is a species?
Answer 1The 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 2The 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 3The 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 do organisms that are well adapted to their environment do?
Organisms that are well adapted to their environment possess characteristics that help them thrive, reproduce, and survive in their specific conditions. They may exhibit traits such as camouflaging, efficient use of resources, specialized body structures, or behaviors that enhance their chances of success in their environment. These adaptations improve their chances of survival and reproductive success, allowing them to pass on these advantageous traits to future generations.
How do organisms evolve through natural selection?
Organisms evolve through natural selection by the process of differential survival and reproduction of individuals with advantageous traits. Variations exist within a population, and those that are better adapted to their environment are more likely to survive and pass on their genes to the next generation. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
Why do populations evolve?
To ensure its survival in its certain environment.
How are sand dollars adapted to its environment?
over time it will evolve depending on its environment

Did you evolve?
Populations evolve, individuals are selected.
It makes them evolve into a way that is adequit for their environment?
Natural selection and it's ability to engender adaptive change in populations of organisms.
Which of the following ideas would follow from the dobzhansky-Mayr theory of speciation?
Isolated populations evolve differences gradually as they adapt to the environment
How do populations evolve over time?
Populations evolve over time through the process of natural selection, genetic drift, gene flow, and mutations. These mechanisms can lead to changes in the genetic makeup of a population, resulting in adaptations that increase the population's fitness and survival in its environment.
Why is DNA mutated?
It is how populations evolve.
What are some factors that are necessary for the formation of a new species?
reproductive isolation: the gene pools of two populations must become separated for them to become new species. As new species evolve, populations become reproductively isolated from each other.

Can populations evolve?
Evolution is the change in allele frequency over time in a population of organisms.Short answer, populations are the only thing that evolves. Individuals die. Traits are passed on to progeny that make up the variations in the populations that evolve.
