Nature and Nurture
A lot of studies are concerned with how much about you was shaped by what is around you
and how much is inherent?
The chances are the both nature and the environment have made some contributions. So
now the question has changed from an either or question to one of mechanisms and
combinations. Eventually, when you have kids, you can start to wonder how much of the
child is nature and how much is nurture, for example, gender clothing.
At birth, the twins were both boys. When they decided to raise the child as a boy, they gave
him surgical and hormonal treatment.
Looking back, it is apparent that there are some gender things that you are born with that
will make sure that you fit in with your assigned sex. Today, it is believed that even though
nurture plays a significant role, nature plays an important one too.
Limits to the power of socialization
What the study showed.
Theory of Evolution
Plays a huge role in our current reflections on why human beings are the way that they are.
Not only do we need the parts to ensure that we survive, we also need the behaviour.
Put forward the theory of evolution with the biggest impact. He had written all of this, but
refused to publish it because his wife was very religious. Therefore he held back his
document for over 20 years, and only published it because someone else was going to beat
him to it.
This is the model that has helped us pull it all together when we try to understand why
living systems are the way that they are. The main point is that species have characteristics
that will maximize the survival of their theory. Fitness is the degree to which characteristics
that you have fit the environment that we live in.
If you have a characteristic that reduces the probability that you will be successful in
carrying out the delivery of your genes (ie: living to reproductive maturity), chances are
your genes will be removed from the gene pool (your genes will die with you). Evolution and Survival
Within any species, while most of the species looks the same, there will be genetic diversity
that allows the species to survive. This is because if there is some sort of change in the
environment, at least some members of the species will be able to live on, and after some
time they come to define the gene pool.
Evolution and Sex Differences
One of the results of evolution is that we will start to see differences in how males and
females behave. Darwin, when pondering, could not believe that peacocks would have
developed such a large, ornate tail just to attract females. Darwin thought that there were
just too many disadvantages to it (cumbersome, problems evading predators, etc) for it to
be an advantage overall.
Basically, males and females of the species will be developing different types of behaviours
that play a role maximizing the probability that they will reproduce. Since the male and
female roles are different, they will have different behaviours. For example, the brighter and
bigger the female is, the more they will be killed and this is not good (eg: peacocks). On the
other hand, males are expendible.
For sexual survival,
