N O T E S
First Ancestors
- Our first ancestors lived 7 million years ago
- Bipedal, upright walking
- Ability to walk emerged long before humankind developed big brains.
- Even though they walked they were still tree climbers.
- No hominins have been found during this period yet.
----------------------
Homonins
- Hominins continued to develop.
- 4 million years ago grasping feet were lost.
- Multiple hominin species lived simultaneously.
- They may have met.
------------
Homo habilis
- 3 million years ago hominins lived in Southern Africa.
- Tools allowed hominins to adapt to new environments.
- The first known stone tools were produced in Ethiopia.
- The tools may have been produced by Homo habilis.
- The Homo habilis is a member of our own genus group, the genus Homo
-------------------
Homo erectus
- 2 million years ago Homo erectus became the first hominin to migrate out of Africa.
- Homo erectus had human-like traits such as:
- large brains
- dexterous fingers
- long legs
--------------------
Brain Growth
- 800,000 years ago advances in cooking was fueling further brain growth.
--------------------
Homo sapiens
- Our own species Homo sapiens emerged in Africa 200,000 years ago.
- They lived alongside and interbred with other hominin species.
- Homo sapiens were highly adaptable, quickly filing nearly every geographic niche.
- Other hominins went extinct.
- Climate pressures and competition with Homo sapiens may have wiped them out.
- Although these ancient hominins are now extinct, they remain our closest relatives on the family tree.

What characteristics attributed to the Homo habilis, Homo erectus and Homo sapiens influenced our species' ability to dance?

Human -like Traits
- Each specie exhibited various degrees of human-like physical and behavioral traits such as: large brains, small teeth, bipedality and tool use.
--------------
Homonins
These homonins can be divided into three main groups:
Early homonins:
Between 7 and 4.4 millions
of years ago in Africa; ape like traits such as small brain capacity,
some were beginning to show some human-like characteristics such as
small canines used more for eating than for hunting or fighting.
Australopithecines:
Primates, 4.4 - 1.4 millions
of years ago across the African continent; they had some ape-like
traits; however, changes in their skull, spine and shift, show a shift
toward a human-like trait, consistent bipedal locomotion
Genus Homo:
2 million years ago; contemporaries of some of the australopithecines, they were becoming distinctly more human; cranial capacity growing larger than any other hominin; sophisticated stone tool technology; the first to control fire; first to migrate out of Africa into the rest of the world.

What characteristics attributed to the Homo habilis, Homo erectus and Homo sapiens influenced our species' ability to dance?
- It is possible to identify the source of the ability to dance in Homo sapiens from the characteristics which were identified for the earlier hominids Homo habilis and Homo erectus. The shift to Homo habilis, which used tools, is a shift to better coordination and fine motor control, a foundation for later physical movement. Homo erectus, with a larger brain, dexterous fingers, and long legs, exhibited physical coordination and cognitive complexity that were increased; both of these are important for rhythm and movement. While Homo sapiens were evolving, their highly adaptable nature, their increased brain size, and their social interaction skills contributed to the further development of the capacity to participate in synchronized and expressive movement. These final developments in motor skills, social bonding, and cognitive functions are what led to the creation of dance as a means of communication and social cohesion and as a ritual.
“ Why is bipedality an important trait for dance development in the paleolithic?”
Bipedality was a crucial trait for the development of dance in the Paleolithic for several reasons. First, it enabled early humans to keep their balance and stability, which are important for engaging in coordinated movements, as in dance. The ability to stand upright also unlocked the arms and hands, which made it possible to use expressive gestures and more dynamic movements, which are a part of dance. Also, bipedality made early humans more efficient in their locomotion and could travel for longer distances and participate in social activities like dance. Since bipedalism is related to the evolution of a bigger brain, it also helped improve coordination and memory, which are essential for learning and executing complicated dance moves. In sum, bipedality provided the physical and cognitive basis for the evolution of dance as a social and cultural activity.
“Why is it significant that these early humans built shelters, buried their dead and created the first objects of art?”
The significance of the early humans' shelters, the burial of their dead, and the first objects of art demonstrate advanced cognitive abilities and social behaviours. The ability to plan, adapt and control the environment is reflected in building shelters, showcasing problem solving and foresight. The emotional depth, social bonding and possibly the beginnings of a belief system is suggested by burying their dead, it indicates an awareness of mortality and respect for the deceased. The emergence of symbolic thinking, creativity and communication is marked by creating art, and it demonstrates the capacity for abstract thought. These behaviors signal the development of complex social structures, culture and cognitive sophistication that define human evolution.
