*** Extinct Primates Allie** 5 different type of ancient primates dating all the way back to 56 million years facial structures continued to change, including relying on sight more then smell. As well as fingers
 * Understanding Our Past 14**

*** A Record of the Past Allie** . Radio carbon: estimation of when body stopped absorbing carbon 14

*** The Dating Game Allie** the dating game: being able to guess and determine how far it dated

*** Fossil Detectives Allie** can tell/determine how they lived/ died…

*** Ancient Environments Aubrey** Pollen past, Told by tools, Appetite (how environments told the stories of their lives)

*** Examining the Evidence Aubrey** Major differences (walking on two feet) arched feet (handling load). Differing diet. Humans were smaller. Fossil allow for reconstruction (short, not a lot of hair, lower jaw and one piece skull)
 * Reconstructing History Aubrey**

*** Faces from Fossils Shelby** Samll changes can help us determine what we looked like Made casts, superficial muscle layers and fake skin

*** Our Family Tree Shelby** 1856 first hominoid was found DNA closest with chimp

*** Living Primates Shelby** 96% with chimp 99% chimpans large brains, hands, advanced vision, few offspring Color vision! (some are nocturnal)

*** DNA: Comparing Humans & Chimps Drew** common ancestor (also look at above notes) 1.2% = 35 million differences

*** Evolution: How It Works Drew** single celled, mutations, natural selection

*** Tree of Life Drew** diagram that shows how all living things are related to each other. Comparing traits or DNA

•	**Family Resemblances Drew** All are related to each other


 * The History of Human Evolution 16

* The First Humans Nakia** Studies have shown that the first human family walked 6 or 7 million years ago 1997 little foot- early species (living 2-4 million years ago)

*** Early Tools Nakia** 2.5 million years ago, judging by tools small brains and disproportionate bodies

*** Turkana Boy Nakia** 5ft tall, more developed then the average 8 yr old today still had baby teeth, young age when death occured

* Many Faces of Homo Jennifer * Out of Africa Jennifer * Peking Man Jennifer

*** Spreading through Asia William** most successful homo erectus called “hobbits” homo floresiensis so small because of pressures

*** The First Europeans William** came from Africa, million years ago, living near mediterrainian

*** New Migrants William** settled in Europe and asia fossils from 200years ago

*** Evolution in Europe Grant** 200-500,000 years ago (Europe) numerous types of fossils were found there

*** The Neanderthals Grant** 1856 neaderthal fossil found no full skeleton chest shape, funnel, masculine fingers and toes. Shorter in stature

*** The Origin of Our Species Grant** not enough evidence to prove Africa. Modern behavior is harder to trace. Some evidence of artwork dating back 35000 years ago

*** The Arrival of Homo sapiens Grant** jebel qasfzeh (barried with young) same and separate species

*** Life during the Ice Age Molly** ice age 15000 years ago. Homo sapiens, clothingate meats and plants avg height 5’3 119 (women) huts, made of mammoth bones fair skin (developed mainly in Europe less UV rays)

*** Expansion of Homo sapiens Molly** tools.. hand axe, microliths, rods for piercings. Homo sapiens were the last hominids Modern humans migrated on foot some by water, start in Africa, second were austrailia to asia. Biering land bridge ( land between Alaska and upper asia) First modern human appeared in Africa

*** The Symbolic World Molly** first symbol 75,000 years old of a horse. Paint and ingravings= art. Then went to terra cotta, main designs were wild horses.


 * One Human Species 6

* Leaving Africa Marie** 150000 years ago our closest ancestors lived in Africa cranium found in isreal

*** By Land and by Sea Marie** ate seafood 50000 60000 crossed 60 miles of open water

*** Steppes into Asia Marie** followed mammoths and bison heard all the way to Siberia 43,000 years ago, (ancient tools)

*** Moving into Europe Demarcus** 99.9% identical amoung each other. 10000year after arrival of homo sapiens hominids died out

*** The First Americans Demarcus** the land bridge connecting asia and America and then over time the ice bridge melted *** Beneath the Surface Demarcus** DNA determines diseases and other things that could have happened, individuality comes from environment not the percentile Scientist should not have groupings because it is inaccurate.

*** The Human Brain Monroe** 3lbs 2.5% of the body (brain) size doesn’t mean anything, 100billion neurons. Same structure for the last 150000 years ago which allowed us to develop art and music, symbolic awakening
 * What Makes Us Human?**

*** Language Monroe** unique to us, not born with specifics, no one knows how it started. Start with simple sounds and body languages.

*** Music Monroe** naturally musically inclined, in every culture music instruments 30000 years old

*** Art Monroe** in every human culture, start with cave paintings, body paintings sculptures.

*** Tools and Technology Fax** tools we have now came from counting devices, fish hooks, cutting tools and pottery they had back then counting device: quipu

*** A World of Human Expression Fax** express ourselves through language and music, art.

*** The Science of Evolution Fax** conflicting with religions, and now its starting to be accepted, ever since Darwin.

Main questions: Will humans evolve? Are we still evolving? Could a new human species evolve? Genetic engineering: choice of how to make people *** Our Future Environment** Environmental challenges: storms, weather, climate, pollution… etc… *** Our Future Universe** Will we still be on the planet?
