Human Bio Notes:

UNDERSTANDING OUR PAST -5 types of Primates -large teeth, large brains -grasping hands and feet with sensitive finger tips and thumbs


 * fossils are physical evidence of previous life or activity of bones protected inside rock sediments.


 * The Dating Game: fossils are dated back further in time depending on their placement in the rock


 * Fossil Detectives: fossils provide proof of when and where new species evolved. They can relate their bones to other fossils to learn about how the species lived and died.


 * pollen can be preserved in lake sediment, tools can help provide more evidence as to what the environment was like when humans began to evolve. look at animal bones at campsites that humans ate and carbon date those and find out what time period the animals where from.


 * we walk on two feet, we are bipeds, chimps are quadrupeds.
 * DNA IS KEY PART IN UNDERSTANDING OUR HISTORY, along with the family tree.

-color vision aids in spotting fruits and nutrient leaves. utilize night vision to hunt.

-Chimps and humans share 98.8% of their DNA and humans and chimps share a single common ancestor.

-every cell that humans have carries 3 billion base pairs, or pieces of info. the 1.2% difference between humans and chimp DNa is equal to about 35 million differences.

-evolution: mutations causes variations in DNA. the fate of traits depends on natural selection.

-tree of life shows how all living things are related to each other. and all living things are related to each other.

- most successful were the homo erectus lived 1.5 million years ago. -first Europeans all originated from Africa, and predicted that the hominids lived nea the Mediterranean Sea.

- NEw migrants settles in Europe and Asia, homo heidebergensis found in Africa

-Our brain separates us, small size, 3lbs 2.5%, 100 billion neurons, generally same for the last 150, 000 years, developed abilities for music and art, symbolic awakening, 100,000 years ago.

- Origins- not much is known: body language, simple sounds, and primates. - humans are naturally musically inclined, a unique function of the human brain, distinct evolutionary function, many different uses, widespread, musical instruments, 30,000 years old, bones - art is interwoven in every human culture - animals do not create art themselves -Origins: cave paintings

What Makes us Human: tools and technology, a world of human expression and the world of science evolution

-first stone tools were found were about 2.5 million years old. the tools are now evolved from those first primate tools.

- oldest fishing hook from 18000 years ago. -we express ourselves through culture like music art, language. and technology.

-the theory of evolution is a very controversial theory and people are starting to accept it into their religion.
