time. Natural selection is where animals with advantageous characteristics produce more offspring‚ therefore passing down favoured genes. In the more developed parts of the world‚ medical care and access to food means natural selection is lesser‚ as selective forces that were there before e.g some diseases and predators‚ are no longer there. Therefore‚ some humans that have characteristics that would have previously meant they produce less offspring‚ reproduce at a similar rate to humans with more

WHY IS SEX FUN? If you were a male would you rather have a beautiful‚ impressive‚ long tail that attracts a lot of women or would you rather have a shorter‚ less attractive tail that enables you to escape from predators more easily? Living out in the wild among many potential predators‚ a shorter tail would seem more logical since it would be a more useful trait than a good-looking one. Though the most logical choice‚ it is not always the case. In many species‚ traits that would normally be considered

Natural selection is mainly thought of as being applied to the biological and physical features of organisms during evolution. The traits that help humans survive through different circumstances will continue to be passed to the next generations because through natural selection the fittest survive. Charles Darwin then applies natural selection to morality in societies. I agree that natural selection can also be applied to the moral faculties of humans. A society’s viewpoint on rationality‚ and what

It is an environment that encompasses the interaction of all living specie.

of Man and Selection in Relation to Sex. In the former‚ he presents his theory of natural selection that results from the struggle to survive (On the Origin of Species‚ 175). In the latter‚ he explains sexual selection that results from the struggle to reproduce. According to Darwin‚ natural selection is one the basic agents of evolutionary change. At the same time‚ sexual selection is divided into the two aspects of intrasexual and intersexual selection. In essence‚ natural selection involves the

Natural Selection Paper Natural selection is considered one of the most important processes for a variety of species and the environment which allows the fittest organisms to produce offspring. To prevent a species from extinction‚ it is necessary for them to adapt to the surrounding environment. The species which have the ability to adapt to new surroundings will be able to pass their genes through reproduction. Within the process of natural selection‚ it is possible for the original genetic make-up

This article was published in the ’current biology’ journal volume 23‚ issue 10. I chose this article because it deals with natural selection‚ which was talked a lot about in Chapter one in our learning and behavior book. Over time a lot of change took place‚ and a lot of it was due to natural selection and how our bodies and traits

introduced to evolution by way of Natural Selection‚ Artificial Selection‚ and Sexual Selection. The process of evolution is seen in species that undergo changes over long periods of time by adapting characteristics which will better suit them to their environments. By utilizing a combination of both hypothetical imagery and scientific observation‚ Darwin has developed a persuasive argument intended to shed light on the origins of life. Natural Selection Natural selection is understood as the evolutionary

ESSAY (Question n°4) For decades‚ humans use natural resources for their development. Today‚ we pay for this exploitation. Human lifestyle are responsible of many effects on environment: global warming‚ climate change‚ depletion of Ozone layer‚ deforestation‚ pollution‚ extinction of species… With depleting resources of nature‚ certain ways to save the environment have to be formulated. But who can do something to save the planet: people or

• Explanation of the concept of natural selection and how it takes place The theory of natural selection was developed by Charles Darwin and Alfred Russel Wallace. They suggested that the mechanism of natural selection was that some organisms have characteristics that are better suited to the environment they live in then others that don’t have these characteristics. These organisms are then more expected to survive to reproduce offspring with these characteristics‚ over generations new organisms
