Transcript of Love: A Mechanism of Evolution

Love: A Mechanism of Evolution Agapé Philia Types of love Greek word for "love"
Often refers to general affection, or a deeper sense of "true love"
Can also be used to denote feelings to one's child or spouse, or for feelings of content or holding someone in high regard
Used in the Bible for sacrificial love
Used by Christians for unconditional love of God Plato's redefinition of Éros Although éros is initially felt for someone, with contemplation it becomes an appreciation of the beauty within that person, or even of beauty itself.
Plato does not say physical attraction is a necessary part of love
Platonic love is love without physical attraction Friendship or affectionate love
Dispassionate, virtuous love
Includes loyalty to friends, family, and community
Requires virtue, equality, and familiarity Agapé
Storge Love; everyone has a different idea of what it is. Its level of importance, moral nuances and general effects in human society are all highly contested, both on a personal and philosophical level. The origins of love are perhaps even more mysterious than its nature - but it can be explained, as a mechanism of evolution. Love has evolved alongside mankind, shaping and being shaped by human history. In order to prove that love is a mechanism of evolution however, it is necessary to find a working, in-depth definition of love. Éros Passionate love, with a sensual desire and longing
Greek for "intimate love"
It does not need to be sexual in nature
It can apply to one you love more than philia, love of friendship
It can also apply to dating relationships and marriage Storge Greek word for “affection”
Natural affection
What a parent would feel for their children
Rarely used, but mostly for family relationships
Can be used to express acceptance or tolerance
"Loving the tyrant" What happens to the brain when in love Certain chemical levels increase, while others decrease
Causes a chemical imbalance
This imbalance is necessary High levels of Dopamine A neurotransmitter
Helps control the brain’s reward and pleasure centres
Helps regulate movement and emotional responses
Helps us see rewards and take actions toward them Low levels of Serotonin A neurotransmitter
Helps regulate learning, mood, sleep, and vasoconstriction
My also play a part in anxiety, migraine, vomiting, and appetite 3 Key components of love Anthropologist Dr. Helen Fisher believes there are 3 key components of love
Lust: Driven by androgens and estrogens, the craving for sexual satisfaction
Attraction: Driven by high dopamine and norepinephrine levels and low serotonin, romantic or passionate love, with euphoria if things are good, intense mood swings if things are not, focused attention, obsessive thinking, and intense craving for the individual
Attachment: Driven by oxytocin and vasopressin, the sense of calm, peace, and stability one feels with a long-term partner Love and Medication Low levels of serotonin can be a contributing factor to depression, but ironically, are required to be in love
Serotonin-enhancing antidepressants can actually inhibit the ability to fall in love
They suppresses obsessive thinking, which is an important part of romantic love

WARNING! This does not mean that you should stop taking antidepressants if you are severely depressed! This just states that you can inhibit your ability to fall in love. Do not potentially risk your life for love if you have life-threatening depression. Society and its views on love Old vs new views (North America)
Portrayal by media (specifically movies)
Valentine's Day (and the commercialization of it) Old vs new views Old views:
between a man and a womansex after marriagetraditionone partner, your spouse (monogamy)
New views:
varies based on cultural and religious backgroundparticipants decide when sex is acceptable in a relationshipsame-sex relationships are acceptedmultiple partners and open relationships are more accepted Movies and Love Various different ideas
Love is perfect (pretty much any romance)
Certain people will never find love (high school romances)
There’s a specific way to get the person of your dreams (romances putting the wrong ideas in your head)
People will just manipulate your feelings for their own gain (one-sided love stories, break-up revenge movies) Valentine's Day Quantifying love in material goods
Love can be bought
“Go big or go home”
Quality measured in material wealth
Specifying a day to be "romantic", probably causing stress for one or both members in a relationship
Making single people feel bad about themselves Love and evolution Origins of love (personal opinion)
How love has affected the progress of society By: Micheil Beale Animals have a base need to find a mate to reproduce for the continuation of their race
They can do this relatively quickly
Compared to other animals, humans:
Have a slower fertility cycle
Have a ridiculously long gestation period that is relatively incapacitating for the female, even after giving birth
Take ridiculously long to mature and become capable of fending for themselves
A mechanism was required within us to keep the male around to care for the female, so she could care for the offspring Here's where love comes into play:
The father loves the mother, so he wants to stay and care for her while she’s incapacitated or caring for the child, and possibly help care for the child himself
The mother loves the child, and wants to care for them until it is able to take care of itself
There is a payoff if the child loves the parent
It wants to care for the parents when they are incapacitated, old, or infirm
This causes a constant loop of love, and a stable support structure is formed Love is no longer just about finding a mate
It's about finding someone you can relate to, and spend your life with
Love is no longer just between a man and woman. Same-sex relationships are becoming more accepted
Same-sex marriage is becoming legal in many countries This is a good example of how love affects and can be affected by society:
It shows persecution based on who you are, who you love
Certain love made forbidden
Freedoms stripped based on how you're born
LGBTQ community uses this video because people in this community are judged and not given equal opportunity because of their sexual preference (who they love)
they are fueled by love to help allow others the right to love whoever they want, and not just that, but fight for anyone who doesn't have equal opportunity because of things the have no control over Love started off as a product of evolution, but it has evolved with society, and helped society evolve. It’s now no longer just about finding a mate, but also about finding someone who you can relate to, someone to spend your life with. Familial love hasn’t really changed much over time. Different types of love are becoming more accepted. Same-sex marriage has been accepted and legalized in many countries, so pursuing your love interest is possible without persecution. Some religions, like certain sects of Christianity, are still against same-sex relationships, but some are becoming more tolerant. Love is a product of physical human evolution, and has contributed to the evolution of human society. References
