The document discusses the evolution of the brain and mind in humans and animals. It covers topics like the growth of the human brain in Homo Erectus, the evolution of intelligence in animals like octopuses, crows and parrots, and theories about the development of different levels of consciousness and cognitive fluidity in humans. The main conclusions are that intelligence began developing after the physical growth of the brain for non-cognitive reasons, and that intelligence is not unique to humans as it can also be seen in certain animal species.

2. Today we are going to talk about..
• the brain growth
• How the mind has evolved after the growth of
the brain
• mind evolution among animals

3. Homo Erectus

4. The Human Evolution

5. Stone tools
of Erectus

6. The brain capacity paradox

7. Increasing of the Brain Size
endurance running theory
Humans are the best marathon runners
Extra brain cells
Long legs body hair (overheating) Sweat
modifications for running

8. Evolution of the mind
First approach: 4 levels of consciousness
Episodic mimetic Mythic Theoretical

9. Evolution of the mind
• Second approach: Cognitive Fluidity
Linguistic (language) Social
TechnicalNatural history
• Autism

10. Misconception of mind evolution
Linear Tree of life

11. Intelligence in Animals
Octopus can :
• Classify objects by size and shape
• Navigate in simple mazes
• Solve problems

12. Intelligence in Animals
The smartest birds are parrots and crows
• crows can make an use tools
• Crows can anticipate unique future events

13. Intelligence in Animals
Alex the parrot

14. Our main conclusions
• Intelligence began developing
only after the physical growth of
the brain due to non cognitive
reasons
• Intelligence is not
unique to humans
Human beings are less unique
then they think of themselves
