Anthropology 151
Human evolution & diversity
Greg Downey, convenor
Once upon a time, when you had a tail.
what is anthropology?
Traditionally, anthropology was the study of ‘primitive,’ non-Western cultures.
When diversity was seen through lens of ‘evolution’ (‘primitives,’ ‘savages,’ ‘tribals’), it made sense to put human evolution in anthropology.
In Australia, anthropology typically the study of cultural diversity through fieldwork.
Holistic anthropology
(biocultural, evolutionary, neuro-psychological)
when studying athletes, we need to understand the origin of and functional capacities of the human body.
how human body can be shaped by our values & obsessions.
sport an area where human diversity is
badly
misunderstood.
Understanding humanity with a multi-dimensional (bio-psycho-socio), cross-cultural & comparative framework.

From Bor-Maor et al. 1980

But isn't the human body perfectly adapted?!
in fact, the body has a host of '
kluges
'
'sub-optimal' solutions to 'design' problems
Throat
breathing, eating & talking plumbing overlaps
Testicles
descent problem & prostate with urethra through it.
Eyes
nerve is in front of the retina
why is this important?
evolution is not 'progress'
Tendency to understand ‘evolution’ through an older model: things improving or becoming ‘more perfect.’

‘Most evolved’ expression.

Teleology
'Great chain of being'
creationists aren't the only ones getting it wrong.
