References. The four main ideas of Darwin's evolutionary theory are variability in populations, overproduction of offspring, competition for resources and inheritance of traits. Variation provides advantages to some members of a population. The surviving individuals pass their traits to the next generation.T he primary mechanism of change over time is natural selection, elaborated below. This mechanism causes changes in the properties (traits) of organisms within lineages from generation to generation. The Process of Natural Selection. Darwin’s process of natural selection has four components. Variation.

One component of natural selection is the fitness level of each individual in a population.

Natural Selection: Natural selection refers to the process that explains why some biological traits increase or decrease within a population. The selection is based on the effect the trait will have on the overall health of the population as certain traits will provide a larger benefit to subsequent generations. Answer and Explanation: 1In later grades, students will learn that there are four essential components of natural selection — an important mechanism of evolution: Variation: All life forms vary genetically within a population. Inheritance: Genetic traits are inherited from parents and are passed on to offspring.

Genetic Variation: Individuals vary from one to another or different beak length. Overproduction of offspring: Individuals tend to produce more offspring in order to survive and produce dozens, but only 2 survive.Darwin’s observations that led to his theory of natural selection are: Overproduction – all species will produce more offspring than will survive to adulthood. Variation – there are variations between members of the same species. Adaptation – traits that increase suitability to a species’ environment will be passed on.This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

Natural selection is founded on three principles: most qualities are inherited (inheritance), more children are born than can survive (competition), and children with more desirable characteristics will survive and produce more offspring (variation). Key points: Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.
