Introduction To Dynamic Evolutionary Psychology
Disclaimer: This introduction goes from the basic ideas of evolution to the theories of evolutionary psychology.
Everything alive,
All living organisms on earth have something common: the DNA.
Life could be summed up as the replication process in which the bodies are vehicles transporting the DNA.
The DNA has specific sequences called genes defining the vehicle's properties.
It is then replicated from one generation to the other.
All living creatures share the same 4 components in their DNA: thymine, adenine, cytosine, or guanine. Only the sequence changes.
Some species have sequences that resemble the sequences of other species. Some parts of the sequences are exactly the same, at the exact same spot. In fact because we all share the basic four components we can definitely find species closer to one another. They have some sort of relation with that other species because they share the same long sequences.
From those relations we can draw a tree of life.
Following this premise, we can deduce that we share a common ancestor, the initial DNA sequence. We can trace that at some point we converged in one single entity.
Then, where does this variety come from?

The replication process doesn't happen randomly.
Because some replicators are better at surviving than others, their vehicle is more suited to their current environment.
Consequently, there's an unbalance in the ones who can transfer their genes to the next generation.

The longer this process goes on the more varieties start to appear.
The diaspora and schism between the genes across a population will grow.

Slight changes will slowly become totally different features.

The abilities that are making one replicator survive and reproduce, giving offspring that will also reproduce taking in consideration the current environment, will be favored and the opposing qualities might not. More on stated clearly
This has been going on Earth for 4.6 Billion years, an immense amount of time.
The code in the genes is a blueprint of the baggages and history the species have passed through to be able to cope with the world it's living in.
Blueprints are chosen through iterations of natural selection.
They are there because the ones in the generations before survived by having them and the ones who didn't did not, or they did but drifted in another direction.
Natural section is the process by which random evolutionary changes are selected for by nature in a consisted, orderly, non-random way.
Some features are there as vestiges. Those now unused qualities might disappear after many generations if they somehow affect the survival and transmission of the genes.
They will have less chance of being in the next generation.
Birds have wings, Fish swim and live underwater, bears have big fur to protect from cold, Leopards run fast, and we, the humankind, have big brains.

We have evolved very large brains.
It goes without saying that they had and still have an advantageous function and help us cope with our environment.
It's an edge against the ones with lesser brain capabilities.

As with everything else, the brain evolved.

But what exactly?
The brain is still thought of as a sort of black box due to its inherent complexity.
We are conducting experiments to answer our questions concerning its mechanism.

One of the oldest is: Are we born as a blank slates?
With no prior knowledge of the world.
We simply have to ask: Wouldn't it give us an advantage to be born with some bits of knowledge about our environment?
Built-in biases or predispositions to help us deal with the world faster instead of having to re-learn and drudge through the drudgery over and over again?
How can we learn anything if we don't already have something to derive it from?
Wouldn't it be faster to just evoke the behavior from our evolutionary past, take some template and apply it.

The human species is certainly having and had challenges that are recurrent; The same set of events keep happening again and again.

It's obvious that as a survival mean the genes would evolve into having a mechanism to cope with the world faster with a low error rate, it would give an advantage.

We can ask:
Are those remnant of the past, vestiges or do they they still apply to our recent world?
If they are vestiges, are they inferring a disadvantage and will they disappear. How stable are those built-in brain features.
You might wonder: Why is this pattern so noticeable in humans.
Are there human universals?

Indeed, some behaviours are common anywhere in the world regardless of the people's origins and environment.
It might seem obvious to most that, for example: Men focus more on sex than women. It is so obvious that they forget to ask why and how or which of those patterns are truly built-in.

What are they?

This is where the field of evolutionary psychology comes into play.

It is about studying those predispositions and why they happen, their relation with their environment, and if they are universal.
But does it imply biological determinism:
We have those biases, does that mean we are meant to do those things?
Are we determined?

This is a wider subject, out of scope but let's just mention that blueprints are there as guides, as foundations, we are free to choose our lives to a certain extent.
Everything is a melange of environment and genes.
This doesn't mean you are doomed to do something.
You still have to take responsibility for your actions.

Blueprints are high levels specifics, the implementations differ.
The field of evolutionary psychology only studies the singular behaviours, what if you could mix them together with the environment and together with group dynamics: social interactions.

Let's define dynamic evolutionary psychology because it sounds like a big complicated word.

To understand it let's take it apart and get familiar with the terms.

Dynamic means anything that is in movement or motion.
Evolutionary relates to the gradual adaptation to the environment, something that has been built through time, a universal property.
Psychology is the science that deals with mental processes and behaviors.

To sum it all, it's the relation and links behind all of our mental processes that have been built through time, universal behaviors.

That's what we're gonna try to achieve.
It's not as scientific as it should be because it cannot be studied on a top down level, and we can't apply strict mathematical rules to it, numeral measures, other than graph theory.
It's not an exact science but it's a relevant one.
However, let's emphasis that every single behaviour mentioned is backed up by multiple scientific studies, the issue is when we mix too many correlations together; This gets close to a conjunction fallacy.
There are many persons reluctant to accept evolutionary psychology.
It's not surprising that it's a controversial subject, it's normal that people fear talking about the biases and the correlation between them; and it is for political and religious reasons.

It's a misunderstanding, we tend to hear relation when in fact we meant correlation. As we've said, those are all just blueprints. No predispositions, just foundations.

Moreover, there's a lot of misunderstanding because some find the fact too obvious. For instance there's a co-relation between fearful events and people seeking more security to protect what they cherish.
It seems obvious and unquestionable when it's something you feel but it doesn't mean it's a reflection of reality.
Dynamic evolutionary psychology is an important topic to discuss because those generic rules, psychological mechanism, are built in us to face problems our ancestors had.
It means we aren't born empty.
We don't have to follow those tendencies. But without bringing them to light we unfortunately cannot help to avoid them.

"The genes hold the gun, the environment press the trigger."

By understanding the regularities within our life we can better interact with one another.
We have awoken to our own evolution.
We can modify our vision and change the world.

> Finding that something is adaptive or was adaptive in part of the past doesn't give us an excuse or justification for the commission of crimes

> Diseases are natural, cancer is natural, lots of things are part of nature, the way we are design, but we choose because of our value system, we interfere. It doesn't mean it's natural that it's an excuse for justification.

- David BUSS.

That is why it is important.
It's a knowledge that brings us freedom.

If we wake up to those facts we won't be bumper cars going around life driven by predispositions.
But without opening the book of our ancestors and self-reflection it is inextricable

Let's open it together and face the facts.
