Evolution Vs Natural Selection Essay

According to Wikipedia,
Evolution is change in the heritable traits of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organization, including the levels of species, individual organisms, and molecules.
As the opposition side, we believe evolution is a fiction.

In darwin’s theory of evolution, it states that “modifications of populations by natural selection, where some traits were favored in an environment over others, Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations. This is called "microevolution."
With no doubt natural selection changes a species, but is this” modification” an …show more content…

No new genetic specifications are being created by natural selection. In fact, what natural selection talking about somehow is a loss of genes – a decrease in diversity.

Why? Here comes a classic example, a small amount of poison dusted onto a crop may kill 99% of the insects, but subsequent spraying is less and less effective. The few survivors of the first pesticide wave are insects that are genetically resistant, carrying an allele that somehow enables them to resist the chemical attack.

The poison kills most members of the population, leaving the resistant individual to reproduce and pass their alleles for pesticide resistance to their offspring. The population of pesticide-resistant individuals then increase in each generation. The example tells us that when one allele is more preferable than the other, it then become more common in the group and the other disappear.
In this case, rise in diversity, evolution, didn’t exist in the process of natural selection.
