Here we have some highlights of how the natural selection works and some of the evolutionary forces that drive evolution: The natural selection operates in base of the difference between de reproductive successes of the individuals. The genes of the most successful individuals (the ones that reproduces more) appears more in the next generation. If an individual cannot survive it will not be able to reproduce. Because of that natural selection is NOT RANDOM and can act really quickly. (Charlat et

Sexual selection was an idea proposed by Darwin and refers to the process in which males and females attempt to maximize their chances of reproductive success. Within a species there are certain characteristics that make individuals attractive to potential mates. An example of this is in peacocks‚ female peacocks are attracted to males with long brightly colored tails‚ even though this makes them easier to be spotted by predators. This characteristic then evolves within the species due to how males

Natural selection forms the foundation of how we understand the ways that species have formed over time. Another form of selection is sexual selection‚ which is the selection of traits based on their roles in courting and mating. It involves attracting a mate with the greatest fitness while simultaneously portraying oneself as the best mate for selection. Fitness‚ described in natural selection‚ is the ability to reproduce and leave successful offspring that will continue the cycle. Sexual selection

The Units and Levels of Selection by Samir Okasha (Ch 8‚ A Companion to Philosophy of Biology) Traditional Darwinian View – * Though Darwin treats individual organisms as basic unit of selection‚ other possibilities can be seen * Lewontin (1970) – Natural Selection will operate on any level that exhibits ‘heritable variation in fitness’. * Hence the question of level seems purely empirical – but is not. Historically – * The debate of Levels of Selection can be traced back to

Natural selection Natural selection is one of the basic mechanisms of evolution‚ along with mutation‚ migration‚ and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To find out how it works‚ imagine a population of beetles: 1. There is variation in traits. For example‚ some beetles are green and some are brown. 2. There is differential reproduction. Since the environment can’t support unlimited population growth‚ not all individuals

research paper is to identify the differences in mate selection strategies of men and women. This paper will first discuss the past research in mate selection tactics. It will then examine the hypotheses of the present research in the light of the studies previously conducted. Consequently it will discuss the method used to conduct present research‚ its results and its findings. Then it will relate the current study to major theories of mate selection. Lastly‚ it will discuss the limitations and the strengths

The Mate Selection This paper compares and contrasts what the secular world presents about how we select our mates and how the Lord directs us to select our mates. The secular world has looked at this process using Sociology and Psychology to answer the question why do we choose our partners. This paper will discuss how culture‚ self preservation‚ and ultimately the Lord will affect the selection of one’s mate.
