Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

In Darwin's theory of evolution by natural selection, the environment is a key driver of the process. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. Environmental pressures, such as competition for resources or changes in climate, drive the process of natural selection by selecting for traits that increase an organism's fitness for survival.
Yes, natural selection plays a role in the evolution of genetic resistance to malaria. Individuals with genetic traits that provide resistance to the disease are more likely to survive and pass on their genes, leading to a higher prevalence of resistance in populations where malaria is endemic. This evolutionary process is an example of natural selection in action.
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.

Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.

Meiosis plays a role in the process of natural selection by generating genetic diversity through the shuffling of genes during the formation of gametes. This genetic diversity contributes to variation within a population, which is crucial for natural selection to occur as individuals with advantageous traits are more likely to survive and pass on their genes to the next generation.

Acquired traits. The theory of evolution by natural selection focuses on inherited traits that provide a reproductive advantage. Acquired traits, which are not genetically determined, do not play a direct role in this process.
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
Reproductive isolation through sexual selection is often an important factor in speciation. This type of natural selection can lead to the evolution of reproductive barriers that prevent individuals from different populations from successfully interbreeding, ultimately resulting in the formation of distinct species.
They both fuel the engine of genetic diversification by creating changes to the linear structure of Dna.
Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
Antigens play a critical role in the human body by triggering the immune response. They are molecules that are recognized by the immune system as foreign, such as bacteria or viruses, and signal the body to produce antibodies to target and neutralize the threat. This helps protect the body from infections and diseases.
Heritable variations play a crucial role in Darwin's theory of natural selection as they provide the raw material for evolution to act upon. These variations are inherited from parents to offspring and can affect an individual's ability to survive and reproduce in a given environment. Natural selection then acts on these variations, with individuals better adapted to their environment being more likely to survive and pass on their favorable traits to the next generation.
