Tool making techniques

Homo habilis

Percussion flakingOldowan Tools

Homo erectus

Acheulean Tools– Hand ax, cleaver, picks, knives– Anvil & bipolar percussion

Archaic Homo sapiens

Levalloisian technique– Many flakes from the core

Hafting

Archaic Homo sapiens

Mousterian tradition– Lighter & smaller– Variety

Homo sapiens

Pressure flaking

If early hominids are our past…

What does the future hold?

Homo erectus evolved in Africa into Homo Sapiens. Then, these earliest Homo sapiens spread “out of Africa” to all parts of the world. Other species found DID NOT play a role in the evolution of humans.

Homo erectus left Africa and evolved separately into Homo sapiens. All species remained similar enough to mate but they did develop differences. (Skin color/eye shape.) One group in Europe evolved but did not survive (Neanderthal.)

The Future of Evolution

Major trends in hominid evolution

Tools are becoming lighter and smaller

Major trends in hominid evolution

Tools are more specialized

Major trends in human evolution

Decrease in size of face and teethLarger brainsReduction of body size and robustness

– ? Obesity rates are rising!

Current Evolution

One species of humansStable brain sizeIncreased intelligenceDeveloped institutions

Current Examples (?)

Wisdom teethStature (People are getting taller)Feet are getting largerEyesight less important

– Glasses/contacts/surgery???????

What will humans look like in the future?

I think….– Larger brain size– More similar to each other– Darker skin due to ultraviolet rays– Smaller jaws (Meals in a pill)– Smaller build (less need for strength)– Air-cars

Our futureWhat do you think we will look like

in 1 million years? What do you think the world will look like?

Draw a picture of humans, their vehicles, their environment, their food, their clothes, etc.
