How does the environment influence our biology,
The role of epigenetics:
The molecules that modify genetic information leading to variation in the phenotype and genetic information, without changing the DNA sequence.
- What is epigenetic? the genetic of the above, studying the differences and changes in phenotype without modifying the DNA sequence. Epigenetics is the change in gene expression due to environmental input
- the role of plasticity and exposure (how can it lead to phenotypic variations)
- What is the link between epigenetics and human behavior?
- molecular conduit: social interaction can affect biology, need to look at what exact processes are responsible for it.
- the importance of causality
- can epigenetic changes be silent
- what are the mechanisms that affect methylation
--> The evidence that there is a variety of different factors responsible for the process of life that goes beyond genes and DNA. (the role of different molecular interaction)
--> methylation is an existing process at all times
--> epigenetic changes to gene regulation

Structure of the essay
How does the socio-economic context influence our biology, also observe the difference within gender as a way to demonstrate our strong dispositions
-
Dedicate a short paragraph to epigenetics and the details of the mechanism as well as its biological and Biochemical role.
1st paragraph defining nature and nurture explains the interdependent relationship between the 2. asking the question where and how to draw the line between experience and biology

-
One paragraph on the three Cs : cognitive, cooperation and culture, serves as an argument to show how environment and biology can be interdependent
The ideas/ key terms of this topic are: Nature, Nurture, behavior, genotype, phenotype, processes (relating to molecules: methylation etc...), causality or cause
Blank slate: individual are modified by ecological factors: experience determines who the person is, (social/ cultural level or biologically? NURTURE
Human nature: attribute or characteristics shared by all humans across the world. innate understanding, NATURE: SHARED BY ALL HUMANS, HERITABLE: if removing the uniqueness can be attributed to nature
Nature via nurture: show how the innate (instinct predisposition etc) and the experience are interdependent, they can each be adaptive or maladaptive: Developmental system theory
Cross cultural universals: some of what we are today must be due to selection therefore mostly nature. way to dissociate the role of nature and nurture would be to study young infants before the influence of their environment kicks in.

- What is the relation between molecular conduit and developmental strategy theory : showing the cyclical between nature via nurture.
