A process of sexual selection by which members of one sex compete with each other, and the victors gain preferential mating access to members of the opposite sex.

Artificial selection, or selective breeding, operates by the same principles as does natural selection, the basis of evolution. These include genetic variation via mutations, differential reproduction and heritability. Humans engage in artificial selection to create specific plants and animals.
For example, the two bucks to the right are fighting, and whoever wins gets the deer to mate and pass down its trait. And who do you think will win? If you said the one that is most fit, then you are right. Its role in evolution is just another part of Natural Selection. It is practically natural selection paraphrased.

Nov 08, 2004 · Sexual Selection Seen in Primate Genes By John Bohannon Nov. 8, 2004 , 12:00 AM Long before DNA was discovered, Darwin proposed that sex is a powerful evolutionary force.

Differential mate selection definition

Specifically, although students can usually assert that some organisms die off because of an unfavorable trait, they often leave out the critical role of differential reproduction and heredity of favorable traits in their explanations of natural selection after completing the activity. Selection differential Harvests ( [dagger]) Block 1 Block 2 Both blocks g [kg. At the youngest age, the selection differential on size is limited by the sum of the selection differentials on [L. Labellum length was chosen, rather than frontal area,... MATE SELECTION THEORIES. Social scientists who study the family have long been interested in the question "Who marries whom?" On one level, the study of mate selection is conducted from the perspective of family as a social institution. Using Revealed Mate Preferences to Evaluate Market Force and Differential Preference Explanations for Mate Selection Article (PDF Available) in Journal of Personality and Social Psychology 96(6 ... Looking for online definition of MATEA or what MATEA stands for? MATEA is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms MATEA - What does MATEA stand for? But just as with natural selection individuals may differ in their ability to reproduce, in sexual selection there can be differential reproductive success among individuals of the same sex (and species). In order to mate, males need to gain access to females and vice versa, and not all individuals will be equally successful at this task. Lecture 3 - Adaptive Evolution: Natural Selection Overview. Adaptive Evolution is driven by natural selection. Natural selection is not “survival of the fittest,” but rather “reproduction of the fittest.” Evolution can occur at many different speeds based on the strength of the selection driving it. Thus, mate selection can be understood at several different, yet inter-connected, levels of analysis. The broader ecological factors discussed earlier provide a good example. Cultural variations in mate choice are not completely random, but often fit with general principles applicable to many animal species (Crook and Crook 1988; Daly and ... Apr 18, 2006 · These forms of mate choice are strongest in large females, suggesting that costs decrease with increasing female size. The genetic association between attractiveness and differential allocation suggests potential for differential allocation to become exaggerated by coevolutionary runaway processes in an analogous manner to pre-copulatory choice. Oct 10, 2017 · A lthough much scientific research has focused on the initial stages of mate selection and mate attraction, and some on mate retention, relatively little attention has been given to adaptations for mate switching. One of the most important involves monitoring a partner’s mate value, which is made up of dozens of qualities. natural selection. n. The process in nature by which, according to Darwin's theory of evolution, organisms that are better adapted to their environment tend to survive longer and transmit more of their genetic characteristics to succeeding generations than do those that are less well adapted.

Mate choice is one of the primary mechanisms under which evolution can occur. It is characterized by a “selective response by animals to particular stimuli” which can be observed as behavior. Fitness is normally defined as the number of offspring an individual will produce. Natural selection works to maximize fitness, because traits can only be selected for if they are passed down to progeny.
