EVOLUTIONARY EXPLANATIONS OF RELATIONSHIPS
- Environment of Evolutionary Adaption
- thousands and
thousands and
thousands and
thousands of years ago
"in the EEA"
- The time
when a
relationship
formation
criteria was
established
- The EEA is NOT a specific time or
place - but the environment to
which a species is adapted.

"in the EEA"
- What is attractive? EG: FACIAL FEATURES
what men think? what women think?
Symmetrical Facial Features .. MALE
(square Jaw, ridged eyebrows, small eyes)
FEMALE (large eyes, small nose, small chin)
- Grammer and
Thornhill 1994

Thornhill 1994
- Partner Selection
- females preferred powerful
males (what does this look like?
modern day? e.g.: financial
security and ambition
- Males preferred youthful
attractiveness - to spread
genes
- NB: LINKS TO PARENTAL INVESTEMENT
- Mate choice is a
product of mate
preference formed in
the 'environment of
evolutionary
adaptiveness'
- females preferred powerful
males (what does this look like?
modern day? e.g.: financial
security and ambition
- Differences in reproductive behaviour ?
- " MEN HAVE MORE SEX" (i don't thin this
really makes sense coz like how can you
have more sex than women if you're
having sex with women?.. ANYWAY the
alleged reason for this "more sex having"
in Evolutionary explanatory terms is
because men want to perpetuate GENE
pool
- concerns with relationships are
seen to involve two priorities (FOR
MEN - concern with sexual infidelity
FOR WOMEN - concern is with
emotional infidelity)
- nature of sexual selection: INTRASEXUAL
= male competition INTERSEXUAL = men
choosing women & women choosing men
- Darwin 1874 - "SEXUAL SELECTION"

- (SEXUAL
SELECTION)
- SEXY SONS -
hypothesis a female
chooses a sexual
partner for
successful and
attractive attributes
as these are likely to
be inherited by their
sons
- SHORT
TERM
MATING
- more vulnerable
- overtime humans
have "evolved" many
mating strategies
- WHY? - the more females
that the male can
impregnate the more
likely they are for
reproductive success
- more vulnerable
- HRB - "Human
reproductive
behaviour"
ESSAY = begin
by talking about
mate choice -
female then
male what they
want/look for -
then link to
Darwins
"SEXUAL
SELECTION"
- WHAT IS HRB ?? - the romantic behaviours in
the present day and how these are explained
by the evolutionary explanations given by
"sexual selection" and the EEA
- humans born
prematurely -
because of head
size
- WHAT IS HRB ?? - the romantic behaviours in
the present day and how these are explained
by the evolutionary explanations given by
"sexual selection" and the EEA
- PARENTAL INVESTMENT
- breast-feeding can last
for up to four years in
some societies. In the
UK and other Western
cultures the average is
between 3 and 12
months VS MEN WHO
COULD HAVE AN
ULIMITED NUMBER OF
OFFSPRING
- Females must nourish the baby for
9 months which means she can only
have a limited number of babies
- Trivers 1972 "any investment by the
parent in an individual offspring that
increases the offspring's chance of
surviving {and hence reproductive
success} at the cost of the parents
ability to invest in other offspring"
- includes provision of resources
(such as food, energy and time
used in obtaining food and
maintaining the home and
territory) time spent teaching
offspring dn risks taken to protect
the young

- FUNDAMENTAL
DIFFERENCES IN
HUMANS sperm
= unlimited &
eggs = sacred
- BIOLOGICAL
INEQUITY - females
must be choosier
when selecting
potential mates -
males compete for
quantity of females
whereas choose
quality male because
of their resources
- OPTIMUM
number of
offspring - trivers
argues that
there is an
optimum number
of offspring for
each parent
- Quality (women)
vs
Quantity (men)
- Quality (women)
vs
Quantity (men)
- SEXUAL & EMOTIONAL
JEALOUSY
- HOW TO BEST PAST ON YOUR GENES? - ONE WOMEN
OR AS MANY AS POSSIBLE (NOTE THE PROPOSITION IS
THAT THE MEANING OF LIFE IS TO SPREAD YOUR
GENES) DOES THIS APPLY TO THE MODERN
RELATIONSHIP? NO.
