Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring. Over time, this leads to the accumulation of beneficial traits in a population, as individuals with those traits have a better chance of passing them on to future generations.
Traits that confer a reproductive advantage, such as increasing survival or attracting mates, are more likely to be passed on to the next generation in greater frequency. This process is influenced by natural selection, genetic variations, and environmental factors that shape the gene pool of a population over time.
The unit of evolution depends on the level at which genetic variation is passed on to the next generation. This can occur at the level of individuals, populations, or species. The unit of selection is the entity on which natural selection acts to drive evolutionary change.
Inherited traits are necessary for natural selection because they are the ones that can be passed down to offspring. Acquired traits, on the other hand, are not directly encoded in an organism's DNA and therefore cannot be transmitted to future generations. Natural selection acts on inherited traits that are heritable and can influence an organism's ability to survive and reproduce.
Mendel's conclusion on the segregation and independent assortment of traits laid the groundwork for Darwin's theory of natural selection by providing a mechanism for how variation is passed down from one generation to the next. This understanding of how traits are inherited allowed Darwin to propose that natural selection acts on this variation to drive the evolution of populations.
Understanding how genetic variation can be inherited from one generation to the next helps support Darwin's theory of natural selection, as it provides the basis for the variability upon which natural selection acts. The mechanisms of inheritance, such as dominant and recessive traits, allow for the passing down of advantageous traits that can confer a survival advantage, leading to their increased prevalence in a population over time through natural selection. By observing how traits are passed on and how they can change within a population over generations, we can see how natural selection can drive the evolution of species.

No, a frog is not an example of natural selection itself. Natural selection is a mechanism for evolution that acts on populations of organisms over generations, influencing the traits that are passed on to the next generation. Individual organisms like a frog can be impacted by natural selection, depending on their traits and how those traits affect their survival and reproduction.

Heritable, meaning that it can be passed down from one generation to the next through genetic inheritance. Without a genetic basis, natural selection would not be able to change the frequency of that trait in a population over time.

Acquired traits, on the other hand, are not directly encoded in an organism's DNA and therefore cannot be transmitted to future generations. Natural selection acts on inherited traits that are heritable and can influence an organism's ability to survive and reproduce.
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.
Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.
