Aristotle
what did they study?
Year?
Mentalism: hylomorphism: the soul is the main entity
300B.C
Andreas Vesalius
what did they study?
Year?
Studied human anatomy (nervous system). familar with brain anatomy. brain was the seed of our understanding
- More evidence-based
1500s
René Descartes
what did they study?
Year?
Dualism:
-brain = basic behaviours (moving, smelling)
- mind = higher though and understanding
1600s
Charles Darwin
and Alfred Russel Wallace
what did they study?
Year?
Materialism: can be explained by science.
- Promoted idea of natural selection
1800s - 1900s
Evidence for species evolution
- fossil records show change in hominid skull
- similar arm bone structure (bat/human)
- selective breeding dogs and plants
- Galapagos islands drought beak size changed in 18 months
Gregor Mendel
- Experiments involving crossbreeding of plants
- coined recessive and Dom traits
– Same time period as Darwin
Baldwin Effect
knowing how to use tools (engraved in genes)
ex: birds when born, know how to use sticks to open nuts instinctivly
How long ago?

First Brain Cell: 700 mya
First Brain: 250 mya

Simple nervous system (2)
Nerve net:
only has reflexive motor responses and no central brain (jellyfish)
Ganglia:
a bit more complex than nerve net
- Ganglia allow this simple cognition
Chordate Nervous System
- true brain
- true spinal cord
- bilateral symmetry
- crossed organization of brain hemispheres
humans, birds, frog, fish
Australopithecus
our distant acestor. we watched a video on how they became bipedalist and used tools
Homo habilis
‘handy human’
used tools
homo erectus
‘upright human’
bipedal
-migrated beyond Africa
-more sophisticated tools
Neanderthals
- europe and asia
- ancient DNA shows interbreeding with modern humans
- had the FOXP2 gene
FOXP2 gene
gene that expresses speech, verbal communication, syllables, sounds
