Darwin therefore suggested sexual selection stating that any characteristic that benefits reproductive success will become the norm over time as it is consistently selected. Sexual selection involves inter and intra sexual selection. Intra sexual selection is the evolutionary process in which members of one sex (usually males) compete with each other for members of the opposite sex. Those who win are able to pass on their genes, which include the factors that made the winning person successful. This helps to ensure the offspring’s survival whilst passing on successful genes.
Genetic influences are referred to as nature. This is that extreme view that all behaviour is controlled by our genetic makeup. This does not just say it’s just the ability we are born with that are demented by genes but also behaviour that appear through maturation (mature as we grow) are determined by genes. For example the 23rd chromosome determines sexual identity. Environmental influence as are referred to as nurture.
This is related to the biological perspective as 'imprinting' images into a brain links to how the newborn organism would act (innate behaviour). Although biology may influence how the brain acts, there are still some flaws in this perspective, such as ignoring cognitive and behavioural explanations. The environment, for example, is but one of the main concepts that have not been taken into
Maslow) • Social Learning (e.g. Bandura) • Operant conditioning (e.g. Skinner) • Behaviourist (e.g. Watson) The theorist whose theory is physical development is Arnold Gesell. His theory is that most physical skills cannot be taught but is programmed in our genetics, which means we will learn different physical skills when our body is ready to.
The offspring have to compete for the limited resources, and individuals with the favorable traits are able to gain the necessary resources for survival. The environment determines if a trait is beneficial or not for example what is beneficial in the artic is not beneficial in the Sahara. If the individual is able to procreate, those favorable genes are passed on to the offspring. If said individual is able to produce multiple offspring, as compared to others, they then have greater reproductive success. Over long periods of time variations in a species occur in a population, so the later generations are distinct from ancestral ones.
Another misconception is that international adoption is more costly than adopting domestically (114). Needless to say, international adoption has much better benefits than domestic adoption because of the thorough and efficient process, fewer concerns, and a wonderful and successful outcome. The process is the most stressful, but integral part of adoption. There is an astounding amount of requirements which families have to abide by to adopt. In general, the prospective parent(s) must be a United States citizen and meet the state’s adoption requirements to adopt (“Who Can
So it is not so much where you are born in your family but how you function that counts. How a person functions generally correlates with birth position. The categories for birth order vary by different studies but generally goes as follows; first child, middle child (first and second born), last born child, only child and twins. Each category has its own traits which can be affected in many ways. Such as the death of the oldest child would cause a second born to be raised as the first born.
First, it will briefly analyse how both genetics and the environment shape human intellect and it will conclude by evaluating intelligence as an intricate result of both. This section will look at some researches which provide proof supporting the hereditary of intelligence. The theory of nature influence argues that human intellect develops his mental ability based on his genes. Furthermore, researchers who defend this point of view completely believe that the environment has no part in determining human intelligence, but they claim that intelligence is a result of genetic factors. Galton in 1875 conducted the first studies supporting this hypothesis.
The key arguments used to support the constitution of species include member of a species share reproduction and evolutionary process. If a member of specie reproduce with organisms of other or same species and produce viable offspring, which can survive and successfully reproduce with other organisms. then that organism is said to be specie. A problem with this method of telling whether an organism is specie is that some kinds of non-sexual organisms, such as bacteria and some eukaryotes have been divided into a wide variety of different species. This problem can be eliminated by using the general idea of specie as an evolving unit which also includes the non-sexual organisms.
In order for a relationship to progress, both partners need to stay motivated in to getting to know each other. The theory stated that a relationship is more likely to be formed if a person meets the needs of the partner and they provide rewards. Relationships provide rewards such as love, company, money (financial security) etc which satisfy our social needs, e.g. self esteem and dependency. So in terms of operant conditioning, the relationship is being positively reinforced because it's rewarding and hence the behaviour involved from both sides is likely to be repeated.
