the factors that are necessary for natural selection by evolution to occur are:
1)variation in characteristics;different individuals in a population must have different characteristics.
2)differencies in fitness different characteristics of different individuals must contribute to differences and fitness.
3)heritability of characteristics characteristics that affects fitness must be heritable.... example:passed by genes from one generation to the next)

Which is not one of darwins four main ideas of natural selection?
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
What are four statements that describe natural selection?
Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce more successfully. It operates on the variation within populations, favoring traits that enhance survival and reproductive success. Over time, this leads to the gradual evolution of species as advantageous traits become more common. Ultimately, natural selection drives the diversity of life on Earth by shaping the genetic makeup of populations.
What is natural selection and what are the four principles that must be present in order for it to occur?
Natural selection is the process by which certain traits become more common in a population due to their advantageous effects on survival and reproduction. The four principles essential for natural selection to occur are: variation, where individuals within a population exhibit differences in traits; heritability, meaning these traits can be passed on to the next generation; competition, as individuals compete for limited resources; and differential survival and reproduction, where individuals with favorable traits are more likely to survive and reproduce, leading to a change in the population over time.
What are the 4 types of natural selection?
The four types of natural selection are stabilizing selection (where the average phenotype is favored), directional selection (where one extreme phenotype is favored), disruptive selection (where both extreme phenotypes are favored), and sexual selection (where traits that increase mating success are favored).
What are the phases of Natural Selection?
The four stages are: Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction
What are the four parts of Darwin's theory of natural selection?
Overproduction, genetic variation, selection, and adaption
12. Which is not one of Darwin's four main ideas of natural selection?
Inheritance of acquired characteristics is not one of Darwin's four main ideas of natural selection. His four main ideas are variation, competition, heritability, and differential reproductive success.

What are four forces that can change the frequency of genes in a population?
- natural selection - sexual selection - genetic drift - immigration/emagration
What are the four pieces of evidence that scientists point to as proof of natural selection?
The four pieces of evidence that scientists point to as proof of natural selection are the fossil record, biogeography, homologous structures, and observable natural selection in action. These pieces of evidence all support the idea that organisms have evolved over time through the process of natural selection.
