Its the process where one common origin diverges into many different variations.
For example. A finch from the mainland diverges into many types of finch on the Galapagos Islands due to different food sources. (large beak to break open seeds, narrow beak to eat grubs etc.)
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.
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.
toilet paper...... just kidding it helps the plants grow and people live
Fertilization plays a crucial role in natural selection by contributing to genetic variation within a population. When organisms reproduce, genetic material from two parents combines, leading to offspring with diverse traits. This variation is essential for natural selection, as it allows certain traits to be favored in changing environments, enabling species to adapt and survive. Ultimately, the differential survival and reproduction of individuals with advantageous traits drive evolutionary change.
The diversity seen in Darwin's finches is a good example of adaptive radiation, where a single ancestral species diversifies to fill multiple ecological niches. This phenomenon highlights the role of natural selection in driving evolutionary change and the importance of environmental pressures in shaping the evolution of species.

Really only natural selection can provide an adaptive direction to evolution. Both gene flow and genetic drift can change allele sequences over time in populations but that is not enough to bring about speciation in those populations. Only natural selection gives you the adaptive change and directional selection that creates new species.
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.
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.
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.
Natural selection does not respect the rights of the individual. If you care for the rights of the individual - your own, for instance - you should avoid being naturally selected against. Fortunately, humans have expanded their control over their environment to such a degree that natural selection no longer has the role in our development that it has for 'wild' life forms. This makes it somewhat easier for us to consider the phenomenon of natural selection from an objective stance.
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.
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.

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.
