Why do populations evolve and become adapted to the environment?

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 do organisms that are well adapted to their environment do?
An organism highly adapted to its climate will continue to evolve over millenia as its environment is constantly changing
Does an individual a population or a species evolve?
Populations evolve.
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.
How do people evolve?
They don't - at least, not individually. Evolution is measured as the shifting of allele frequencies in populations.
What happen when organisms populate a new area and are isolated geographically from other populations of the same species?
The species will eventually evolve to be similar, but not exactly like the main species.
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
What do organisms that are well adapted to their environment do?
An organism highly adapted to its climate will continue to evolve over millenia as its environment is constantly changing
Did people adapt or evolve?
To begin with we adapted and evolved, now we apapt the environment to us where animals do not.
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.
Did you evolve?
Populations evolve, individuals are selected.
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
Does an individual a population or a species evolve?
Populations evolve.
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.
