"traits will be passed down into successive generations. Natural selection explains how species can change in what we might call an by adaptation to their environment; it is the primary mechanism of evolution. Darwin called this an "inescapable conclusion" that followed from two "self-evident" premises. (1) organisms tend to overpopulate a region and there are only enough resources for some to survive, and (2) every individual is slightly different (posses unique traits). Thus, the individuals within a population that are best suited to a given environment will survive and reproduce and this inheritable trait will become increasingly common in the population over time. Examples Darwin sights are that he observed subtly different varieties of finches on the Galapagos Islands, each adapted to its local environment. In addition, ancient fossils have been found that resemble modern-day animals, but with key differences that support the evolutionary model. Darwin observed that examples of artificial selection, such as dog breeding, can isolate preferred traits in relatively short time spans, and is a sensible analog to natural selection. Natural selection is also becoming a big problem for many kinds of bacteria and viruses that evolve to be drug-resistant."(Churchill)

According to Darwins theory of evolution what do organisims compete for?
According to Natural Selection organisms compete to live. Now saying that, Natural Selection encompasses a whole range of competition, from competing for food to competing for mates. It is this competition as well as adapting to environments that hones in on variation and drives the change in species.
Why is an animal cell good at its job?
Because it its not then it gets eaten. That's what drives evolution.
What drives the process of evolution?
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
What is the theory of evolution?
Evolution is the change in allele frequency (genotype) over time in a population of organisms resulting in alterations of the phenotype. Change over time gives rise to the diversity of species.The theory of evolution by natural selection is the nonrandom survival and reproductive success of randomly varying organisms. This is the main adaptive driver of evolution and can lead to speciation. All organisms are variations and the environment, the natural selector, preferentially chooses those with beneficial traits to be reproductively successful in the immediate environment at a greater rate than their fellow population members. As their descendents possess these traits, the alleles shift in the population gene pool and evolution occurs. Gene flow and genetic drift also cause evolution, especially in small populations, but they are not adaptive drivers.Basically, theory of evolution is the theory that explains the diversity of life. Many believe the father of evolution was Comte de Buffon, a French naturalist. However, he was unable to come up with a reasonable mechanism that drives evolution. Charles Darwin later came up with natural selection as the mechanism that drives evolution and wrote about it in his book On the Origin of Species.
How does coevolution differ from evolution?
It doesn't. Co-evolution is simply a special case of evolution in which two or more species affect the direction of one another's evolution. The classic example is predator/prey interaction. All rabbits are variants and all fast rabbits vary among themselves also, with the faster ones surviving to reproduce ever faster rabbits. ( within physical limits and incrementally; think of how humans have shaved time off the mile run in the last 50 years ) This drives the evolution of faster, within limits, predators to chase these rabbits. Thus you get a arms race of coevolution in two interacting organisms.
What drive the theory of evolution?
I assume you mean natural selection drives evolution.

Why is an animal cell good at its job?
Because it its not then it gets eaten. That's what drives evolution.
Why does evolutionists claim that natural selection supports evolution?
Because it does! Natural selection is the best explanation of adaptive change that we have and drives much of evolution. talkorigins.orgPS: Evolutionists is an ideological, not a scientific term
How do you write a sentence using the word stellar?

What is the moment when a character's fortunes change and the plot drives towards the conclusion of the story?
The turning point is when the character faces a critical decision or event that significantly impacts the direction of the story. It propels the plot towards its resolution by pushing the character into a new trajectory or situation that drives the narrative towards its conclusion.
Evolutionists often make the distinction between evolution as a fact and evolutionary theory What does this mean?
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
What drives the process of evolution?
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
What role does natural selection play in microevolution?
First, I should mention that 'micro-evolution' is not a process in itself. Rather, it is a perspective on the effects of evolution. 'Micro-evolution' is those effects seen from close-up; by 'zooming out' one sees those same results in a wider scope called 'macro-evolution'. All evolution is driven by genetic variation and natural selection. Natural selection drives evolution by filtering out some variations while promoting others, thereby directing the slow change of morphology and behaviour of populations.
