What are some primal instincts?

Primal instincts are behaviors and drives that are deeply ingrained in human nature and play an important role in survival. These instincts originate from our evolutionary past and helped early humans adapt and thrive. Though modern society is much different, these primal urges still influence human behavior in powerful ways.

Fight or Flight Response

One of the most well-known primal instincts is the fight or flight response. When faced with danger, humans instinctively experience a flood of physical changes – like increased heart rate and adrenaline production – to prepare the body to either stand and fight or flee to safety. Though not as necessary now, this instinct evolved to deal with threats from predators or hostile humans.

Physiological Changes

The fight or flight response involves wide-ranging physiological changes, including:

  • Increased heart rate and blood pressure
  • Accelerated breathing
  • Sweating and heightened senses
  • Release of glucose for a burst of energy
  • Increased muscle tension and strength

These automatic bodily responses equip an individual to stay and battle a threat or run away as fast as possible.

Brain Changes

The brain also undergoes changes, including:

  • Activation of the amygdala, the fear center
  • Suppression of non-essential brain areas like the prefrontal cortex
  • Release of neurotransmitters like adrenaline and dopamine

These neural responses sharpen focus, dull pain, boost motivation, and drive instinctive fight or flight behaviors.

Behaviors

Common behaviors sparked by this primal instinct include:

  • Aggression or physically fighting back
  • Fleeing immediately without thinking
  • Yelling or shouting in panic
  • Freezing in place

Though this primal reaction can be helpful for survival, it can also lead to inappropriate responses in modern society.

Reproduction and Sexual Urges

Another fundamental primal drive is the instinct to reproduce. Passing on one’s genes to the next generation is essential for evolutionary success. Powerful sexual and reproductive urges ensure humans seek out partners and engage in sexual activity.

Physical Drives

Physically, the human body has evolved many traits to promote successful mating, like:

  • Developing secondary sex characteristics during puberty
  • Ovulation and menstruation cycles in women
  • Production of sperm and testosterone in men
  • Physical pleasure and orgasms from sex

These biological processes stimulate sexual interest, arousal, and intercourse leading to reproduction.

Behavioral Drives

On the behavioral side, humans also exhibit innate drives like:

  • Flirting, courtship rituals, and mate selection
  • Motivation to have frequent, enjoyable sexual intercourse
  • Seeking physical attractiveness in partners
  • Same-sex attraction in some individuals

These behavioral instincts evolved over time to maximize chances of passing on genes.

Emotional Drives

Reproductive instincts also involve emotional components like:

  • Romantic love and attachment to partners
  • Sexual jealousy towards romantic rivals
  • Feelings of protectiveness towards family members
  • Joy and bonding from physical intimacy

These emotional drives strengthen reproductive bonds between mates and kin.

Self-Preservation

Self-preservation is a primal drive to ensure one’s own survival. This includes instincts like:

Hunger

The hunger drive motivates humans to seek out food and avoid starvation. Key elements include:

  • Appetite signals when the body needs nourishment
  • Seeking calorie- and nutrient-rich foods
  • Eating until satiated
  • Cravings for fat, sugar, and salt

Though extreme hunger is rare today, this primal drive remains strong.

Thirst

Thirst instincts compel the body to replenish fluids, including:

  • Feeling thirsty as dehydration increases
  • Seeking out and consuming water
  • Preference for cool, clean water
  • Drinking until quenched

Dehydration can be fatal, so this is an important self-preservation urge.

Sleep

Sleeping is also essential for survival. Key sleep instincts and drives include:

  • Feeling tired after long wake periods
  • Seeking shelter and safety to sleep
  • Preference for nighttime sleep
  • Urge to sleep when extremely tired

Though lack of sleep is not immediately fatal, rest and sleep remains a primal need.

Security and Shelter

To aid survival, humans also instinctively seek security and shelter:

  • Seeking safe locations away from hazards
  • Desire to control and defend territory
  • Building physical shelter for protection
  • Storing extra provisions

These self-preservation urges remain influential in modern society.

Group Living and Tribal Bonds

Historically, human survival depended greatly on close social groups and tribes. Key social instincts include:

Safety in numbers

Humans have an innate drive to live in groups, likely because there is safety in numbers against threats.

Social bonding

Strong social bonds and connections evolved to hold groups together, including:

  • Making friendships and alliances
  • Caring for infants and family members
  • Romantic pair bonding
  • Playing, laughter, and group activities

These social instincts strengthen group cohesion and loyalty.

Group identity

Tribal groups often have strong shared identities, including:

  • Symbols, rituals, and traditions
  • Shared purpose and values
  • Language, stories, and culture
  • Group defense against outsiders

These help create an “us vs. them” mentality that solidifies tribes.

Hierarchy

Human groups often have hierarchical structures with leaders and followers:

  • Seeking leadership roles and status
  • Granting authority to dominant members
  • Obeying group norms and leaders
  • Punishing dissent and betrayal

These instincts help organize social systems and maintain order.

Curiosity and Exploration

An innate human drive for curiosity and exploration also evolved as a survival advantage. Key elements include:

Novelty-Seeking

Humans instinctively seek out new stimuli, environments, and experiences:

  • Boredom from routine and familiarity
  • Thrill from unfamiliar and unexpected
  • Draw towards mystery and unexplored areas

This primes humans to investigate new territories and discoveries.

Risk-Taking

Exploration often requires calculated risk-taking, like:

  • Willingness to leave comfort zones
  • Bravery and resilience against harm
  • Ability to recover from mishaps
  • Learning from mistakes

These traits allow profitable exploration and expansion.

Mastery

Humans also strive to master new environments and situations:

  • Pushing limits to gain competence
  • Pride and satisfaction from accomplishments
  • Seeking greater challenges after mastery

These drives help humans become capable of exploiting new territories.

Creativity

Human creativity generates new innovations that aid survival, including:

  • Imagining better solutions
  • Inventing new tools and technology
  • Creative problem-solving
  • Art, storytelling, and culture

This ability to innovate gave human ancestors key advantages.

Defense of Property and Resources

For ancestral humans, property and resources were essential for survival and propagation. Key related instincts include:

Ownership

Humans exhibit a primal sense of ownership over their property:

  • Marking territory as belonging to oneself
  • Feeling of right to control owned resources
  • Anger and defense against theft
  • Reward circuits in acquiring new property

These instincts help humans secure essential resources.

Protection

Humans are very protective over their resources and possessions:

  • Guarding property from harm or loss
  • Willingness to fight intruders and thieves
  • Preferring hidden, locked storage
  • Seeking insurance and security measures

Vigilance and protection fuels survival capability.

Acquisition

There are also innate drives to acquire resources:

  • Work ethic to obtain vital resources
  • Urge to bargain, trade, and profit
  • Competitiveness over limited resources
  • Excitement and greed from big gains

These acquisition drives distribute resources efficiently.

Saving

Humans also tend to save excess resources when available:

  • Squirreling away extra provisions
  • Avoiding unnecessary expenditure
  • Planning and delaying gratification
  • Distress and anxiety from wastefulness

Saving during abundance buffets against future scarcity.

Key Questions

In summary, some key questions about primal human instincts include:

  • What core behaviors and motivations are inherited from our ancestors?
  • How do primal drives for survival, reproduction, security, and resources continue to influence humans today?
  • Which instincts generate helpful vs. disruptive impulses in modern society?
  • Can human higher cognition overcome primal urges when necessary?
  • How do factors like group identity, hierarchy, and territory still impact social structures and politics?
  • Are primal instincts hard-coded into human DNA or conditioned by environments?

Understanding these innate urges provides insight into human nature and our shared evolutionary roots.

Conclusion

Primal human instincts are innate drives and behaviors programmed by natural selection over hundreds of thousands of years. Though civilization has changed drastically, these primal urges for survival, reproduction, security, social bonds, exploration, property, and resources continue to shape human motivations and actions. These instincts can spark both constructive and harmful impulses in today’s world. Understanding our primal human nature provides useful perspective on why we are the way we are, and how best to construct modern societies.
