What else can I help you with?
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
what causes changes in frequency?
There are three main mechanisms that can cause changes in allele frequency.These include natural selection, genetic drift, and gene flow.
Is natural selection a cause or effect of organic evolution?
Natural selection is a cause of organic evolution. It is the mechanism by which certain traits become more or less common in a population based on their advantages or disadvantages for survival and reproduction in a given environment. As organisms with favorable traits are more likely to survive and reproduce, these traits become more prevalent over generations, driving the process of evolution. Thus, natural selection leads to changes in the genetic makeup of populations over time.
What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
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.
Why are evolution and adaptive capacity necessary responses to natural and unnatural mechanisms that cause changes in the biosphere?
If the species can not adapt to changes in the environment they will die out.
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
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
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.
