suggested that species evolve through sexual selection which involves attracting the mate with the greatest fitness and at the same time maximizing the chances of being selected as ‘fit’ themselves. Fitness‚ in the context of the evolutionary theory‚ means the ability to reproduce and have offspring‚ making it more likely for them to pass on their genes to the next generation. To explain this‚ Darwin came up with the two processes: Intra-sexual selection refers to the evolutionary process where members

Discuss the relationship between sexual selection and human reproductive behaviour. (24) Sexual selection can be used to explain certain characteristics or behaviours which increase an individual’s reproductive success. These characteristics may get exaggerated over evolutionary time. In humans‚ these characteristics may include good physical and mental health‚ as well as physical features such as good looks etc. these characteristics are attractive because they show an ability to reproduce and

AO1 Psychologists suggest that there is a relationship between human sexual selection and reproductive success. Explaining this relationship there is intra-sexual selection and inter-sexual selection. Intra-sexual selection suggests that members of the same sex compete with each other in order to get a member of the opposite sex and ensure reproductive success. The winner mates and then passes on their genes. Whichever traits led to their success i.e. health because there genes are stronger‚ will

This debate has been ongoing for literally centuries despite one side being embarrassingly unprepared. The amount of plausible and logical arguments the theory of Natural Selection brings to the table far outnumbers those of Intelligent Design. Intelligent Design proposes that “God” created earth.

and compare them to the accepted Darwin theory of Natural selection. A pre- Darwin explanation of evolution would be Jean- Baptiste de Lamarck’s theory of acquired characteristics. Which he thought that evolution and adaption to the environment does occur and causes diversity. His theory was that species inherit acquired characteristics and that more complexed organisms came from less complexed ones. Darwin’s theory of natural selection is the adaption to the environment under certain conditions

Natural and Sexual Selection of Vestigial and Wild Type Drosophila melanogaster Abstract In this experiment‚ vestigial flies as well as wild type flies were used to create some diversity as well as test one of our hypotheses. Our hypotheses are as follows; 1) The wild type flies will have a greater relative fitness compared to the vestigial flies based on only sexual selection. The wild type has a relative fitness of 1 since it has fully functional wings. Vestigial Winged flies are not as sexually

relationship between sexual selection and human reproductive behaviour. (24 marks) The nature of sexual selection is derived from the evolutionary theory. This suggests that the people who we choose to have sex with has been born into us and is an innate response we have. It also suggests that all behaviours are adaptive‚ including relationship formation‚ therefore forming a relationship should help out ‘survival’ in the way of passing on our genes. There are 2 types of sexual selection‚ of inter and intra

Write this as if you are trying to explain evolution by natural selection to someone that “doesn’t believe in evolution”.

Humans in technology environment are not very free from natural selection. According to Charles Darwin‚ natural selection acts only for the good of each organism‚ so since our very first human ancestors had no natural defenses‚ they would die from what is considered today an insignificant disease. It was throughout millions of years‚ that the human body started to build an immunization to certain diseases and only the stronger humans were the ones to survive and carry on that trait. Likewise‚ having

The argument will be developed by a critical review of Zibarras and woods’ research‚ discussing in turn its background‚ methods‚ results‚ discussions and implications. The paper of Zibarras and Woods reports a study examining the selection methods in 579 UK organizations representing a range of different industry sectors and organization sizes. In this
