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.)
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
