How do variations work?
Variations in living organisms arise through changes in DNA during reproduction, resulting in differences in traits. These variations can be caused by genetic mutations, environmental factors, or a combination of both. Natural selection acts on these variations, leading to the evolution of populations over time.
Can RNA undergo natural selection and evolve?
If RNA is used as a genetic molecule, passing traits from parent to offspring, then it is subject to natural selection. This only happens in a number of viruses and very few bacteria, though: most organisms use DNA as their genetic molecule.
How do mutations affect variations within organisms?
Mutations can introduce new genetic variations within a population by changing the DNA sequence. These variations can lead to differences in physical traits, behaviors, or disease susceptibility. Over time, if these variations provide a benefit in a specific environment, they may become more prevalent in the population through natural selection.
What is the relationship between genetic variations and mutations?
Mutations are random changes in DNA; genetic recombinations are new arrangements of genetic material (as a result of sexual reproduction). Together, they are the "fuel" that powers the "evolution machine," the direction of which is determined by natural selection.
The process of making recombinant DNA is least related to?
The process of making recombinant DNA is least related to natural selection in organisms. Recombinant DNA technology involves the manipulation of DNA in a laboratory setting to create new genetic combinations, which is different from the natural selection process that occurs in nature over generations.

What is the selective agent in natural selection?
They are the selective agent in natural selection ;)
Why are chimpanzees brown and black?
evolution. variation and natural selection. DNA!!!!
Explain how the structure and function of DNA enable species to change over time through natural selection.?
The structure of DNA allows for genetic variation through mutations, which introduce new traits into a population. Natural selection acts on these variations, favoring traits that increase an organism's fitness for its environment. Over time, these advantageous traits can accumulate in a population, leading to species adaptations and evolution.

What process provides the genetic variability that natural selection acts on during evolution?
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
How do DNA mutations impact genetic diversity and evolution?
DNA mutations impact genetic diversity and evolution by introducing new genetic variations into a population. These mutations can lead to changes in traits and characteristics, which can be beneficial, harmful, or neutral. Over time, these variations can be selected for or against through natural selection, influencing the overall genetic makeup of a population and driving evolution.

what was Darwin's concept of natural selection was not influenced by?
Knowledge to the structure of DNA.

How would any changes in a mammal be passed on from generation to generation?
Through DNA, Genetics and Natural Selection.
