Is natural selection a cause of evolution?

No, natural selection is believed to result in evolution.


What characteristic within populations cause natural selection to occur?

Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.


Which mechanism of evolution can cause adaptation?

Natural selection.


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.


What is the relationship between evolution and natural selection?

Evolution is the process of change in species over time, while natural selection is a mechanism by which evolution occurs. Natural selection acts on genetic variation within a population, favoring traits that increase an individual's chances of survival and reproduction in a given environment. Over time, these advantageous traits become more common in the population, leading to evolutionary change.


Can RNA undergo a natural selection and cause evolution or change?

no


How did Darwin explain why Galapagos species had different adaptions and similar South American species?

Define the term Variation and natural selection how do they work together to help cause evolution


What is the mechanism of evolution?

The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.


What factors might be responsible for variation in measurements of traits such as the heights of 10yrs old pine trees or the kidney filtration rates of 10 replicate lab mice?

genetics, evolution, and natural selection can be the cause of variations.


What are the alternatives to evolution and how do they differ from the theory of evolution?

The main alternatives to evolution are creationism and intelligent design. Creationism posits that a divine creator is responsible for the origin of life and species, while intelligent design suggests that certain features of living organisms are best explained by an intelligent cause rather than natural selection. These alternatives differ from the theory of evolution in that they do not rely on the scientific principles of natural selection and genetic variation to explain the diversity of life on Earth.


How does variation work to help cause evolution?

You have to have variation in order to be able to have more successful variations, which succeed in evolutionary terms, and less successful variations which fail. If there were no variation in a species, there would be no natural selection.


What is the cause and effect of Darwin's theory?

The cause of Darwin's theory of evolution was his observations of natural variation and adaptation in species during his travels, particularly in the Galapagos Islands. The effect of his theory was a paradigm shift in biology, leading to a better understanding of how species change over time through the process of natural selection.
