Natural selection (survival of the fittest) is a key mechanism driving evolution but they are not the same. Evolution encompasses all changes in allele frequencies in a population over time, while natural selection is one process that can lead to those changes by favoring certain traits in individuals that increase their reproductive success.

What is the goal of evolution?
In the short, intermediate, and long term, the function of evolution is the survival of the species or genera. In the very long run, thermodynamics tells us that entropy will ensure that there are no energy sources available - all the bits will be equal. Whether entropy applies to information is a thought worth perusing.
What is the importance of crossing over in the process of evolution?
Gentic variation. If every set of DNA was equal, there would be no vartiation and no evolution. Fortunately, crossing over is a common process that helps with genetic variation so that no two people, animals, or plants have the same DNA. Crossing over only really occurs in eukaryotes, so this is why it helps with the evolution of plants and animals. "Sexual reproduction and recombination of linked genes (crossing over) are along with mutations the main instruments of biological variability. Sexual reproduction allows many combinations between genes situated in different chromosomes. Crossing over, however, is the only means to provide recombination of alleles located in a same chromosome. Crossing over probably emerged and has been maintained by the evolution because of its importance for the biological diversity. " See: http://en.wikipedia.org/wiki/Chromosomal_crossover
How does water move from high to low concentration in a natural system?
Water moves from high to low concentration in a natural system through a process called osmosis. Osmosis is the movement of water molecules across a semi-permeable membrane from an area of higher concentration to an area of lower concentration. This movement occurs until the concentration of water is equal on both sides of the membrane.
How does osmosis keep living healthy?
Because cell always need water let cell keep equal and healthy.
What condition is necessary for a body to resonate with a vibrating source?
The conditions necessary for a body to produce sound are first that their must be a medium for the sound to travel through. Then their must be a disturbance in the medium that pulses through the medium .

What is the ultimate goal of evolution?
In the short, intermediate, and long term, the function of evolution is the survival of the species or genera. In the very long run, thermodynamics tells us that entropy will ensure that there are no energy sources available - all the bits will be equal. Whether entropy applies to information is a thought worth perusing.
Why did progressive reformers reject Social Darwinism?
Progressive reformers rejected Social Darwinism because they believed in promoting social welfare and equality, which was in direct opposition to the survival of the fittest mentality of Social Darwinism. They emphasized the need for government intervention to protect and uplift the less fortunate in society, rather than letting natural selection determine outcomes.
How did naturalism challenge the idea of social Darwinism?
Naturalism challenged the idea of social Darwinism by highlighting that not all individuals have an equal opportunity to succeed due to factors outside of their control, such as environment, genetics, and social circumstances. Naturalism emphasized the role of these external factors in shaping an individual's destiny, as opposed to social Darwinism's focus on innate superiority and survival of the fittest.
What substance is equal in hardness to a diamond?
No natural substance is equal in hardness to a diamond.
What is the least natural number divisible by each natural number less than or equal to twelve?
It is 27720.
Is -a a natural number?
No. Natural numbers are 0, 1, 2, 3 ... If a was defined to be a negative integer, then -a would equal a natural number. But -a is a variable with a sign, not a natural number.
What pace is equal to one natural step?
30 inches
What are some animals that eat tigers?
Since tigers have no natural predator, the only scenario in which it is eaten is either one in which it has died of natural causes and scavengers like vultures or wild boars eat its carcass, or one in which survival is thoroughly threatened, and the tiger is extremely weak, and a rival predator of near equal power kills it to survive. The second case very seldom occurs.
Can evolution occur without natural selection?
Natural selection is the differential fitness of diverse phenotypes, causing some individuals to reproduce more than others according to their own relative fitness. Evolution is the change in gene frequencies of a population between generations. Therefore, natural selection can indeed occur without resulting in evolution, as changes in mean fitness do not necessarily lead to changes in gene frequencies. For example, a deleterious allele may affect only homozygotes in a population. Thus, homozygotes may be selected against in equal proportions, causing them both to decrease in frequency at the same rate. While heterozygotes would have higher fitness, the mean change in frequencies would still equal zero. Both the dominant and recessive alleles are still present at the same frequency as before they were acted on by selection, due to the relative increase in heterozygotes.
What is the concept that all people are of equal worth called?
Natural Equality.
Is negative 12 a natural?
No. "Natural numbers" only refers to integers greater or equal to zero, that is, non-negative integers.
