How is kin altruism related to natural selection?
Kin altruism is the tendency to behave in such a way as to provide benefit to a close relative at personal cost. One might think of sharing food, or calling out when a predator approaches. Natural selection is the differential replicative success of alleles. If one considers altruistic behaviour as (influenced by) the expression of a complex of alleles, then it is easy to see how aiding organisms that share most of your alleles (ie. relatives) would cause those alleles to spread throughout the population gene pool at an increased rate. In this manner, altruism could evolve as a result of natural selection acting on 'selfishly' replicating genes.
Is adaptation a cause of natural selection?
No, it's exactly the other way around: natural selection causes adaptation.
Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
What are the advantages and disadvantages of natural selection to an organism?
Natural selection can help creatures adapt to their enviorment. Sometimes this can cause unwanted problems.
Can RNA undergo a natural selection and cause evolution or change?
no
How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
Can someone help you compare and contrast natural selection and evolution any help would be great?
Evolution is simply genetic change within a poulation. That change can occur in several ways. One is immigration/emigration: individuals moving in or out of a population bring in or take out their alleles with them. Another is genetic drift, or chance events which cause the frequencies of alleles in a population to fluctuate. New mutations can change the allelic frequency as well. Finally, natural selection can cause some alleles to become more common at the expense of others. In short, natural selection is one of several mechanisms that can bring about evolution.
What indicates that evolution is occurring in a population in genetic terms?
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.

How may natural selection be able to cause evolution to occur?
By selecting the variant organism most suited to the environment the alleles of the population then change in frequency over time and thus evolution occurs.
What is the relationship between evolution and natural selection?
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Is natural cause the same as natural selection?
No, they are two different things.
Is adaptation a cause of natural selection?
No, it's exactly the other way around: natural selection causes adaptation.
Which mechanism of evolution can cause adaptation?
Natural selection.
What can cause natural selection to go faster?
mutation
Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
