On July 1, 1858, a joint paper on the subject was presented and subsequently published. Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features. Without a working knowledge of natural selection, it is impossible to understand how or why living things have come to exhibit their diversity and complexity. An understanding of natural selection also is becoming increasingly relevant in practical ...

Finally, the most famous mechanism of evolution! Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next. Natural Selection in a Nutshell: Natural selection is the process by which individuals better adapted to their environments survive longer and reproduce more. Natural selection acts on phenotypes, or physical traits, that confer an advantage in fitness at the individual level, thus altering allele frequencies at the population level.Natural selection and the heritability of fitness components.

An understanding of natural selection also is becoming increasingly relevant in practical ...Sexual selection is not a subcategory of natural selection, as Darwin made very clear: it arises from differences in mating success, whereas natural selection is due to variance in all other fitness components.

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.Figure A.2.2 illustrates one possible learning environment from the perspective of a teacher or instructor. A teacher may have little or no control over some components, such as learner characteristics or resources, but may have full control over other components such as choice of content and how learners will be supported.
