What can we learn about human health in the past from fossils from humans?

The shift from forging to farming had generally negative consequences for lifestyle and health. • changes in food consumption in food preparation technology alterations to skull and teeth. • workload and activity in general altered populations around to begin to produce their food by farming/ herding.

Soft food and it's relationship to biological change in humans?

The shift to agriculture and the eating of softer resulted in biological changes to face, jaws, and teeth of modern people. Tendencies characterized the skull and teeth of hunter-gatherers.

Important milestones Upper Paleolithic

• 50,000 to 10,000 yBP •a period of cultural fluorescence when fully modern humans (fmh) move in Europe • advances include -> tool technology highly specialized utilizing bone anther, shell, and ivory • invention of the Attatl for hunting • domestication of dogs • appearance of many types of art and decorations • FMH spread it to all areas of the earth.

What are some of the nutritional consequences of becoming an agricultural society?

• Heights have declined • with the height decreasing comes from stress • smaller body does not confer an adaptive advantage.

What are some the disadvantages becoming an agricultural society?

• Increased demands on the environment • pollution • creates social stratification and conflict • decline biodiversity • health cost and quality of life implications.

Globesity vs. malnutrition

• about 7.5 Bil people on earth 1 bill is suffering from malnutrition • many countries globalize and raise living standards they also do high fat, carbohydrates diet. • 5000mil leading to a lot health issues (west disease)

How did agriculture affect human living circumstances?

• agriculture (cause of population increase) crowding - causing conditions conductive to spreading and maintenance of infections and diseases. • Nutrition shifted - Poor diet • agriculture caused declining in workload and activity.

Regions where agriculture was invented independently and their chief products

• domestication- started in at least 11 different regions around the world. • farming began in the southwestern Asia —> 11,500-8,000 bYP.

when, where, and why did agriculture develop?

• during the Holocene epoch, (most recent 10,000 years) people included domesticated plants and animals in their diets for the 1st time. • their earliest agriculture occurred in the eastern Mediterranean (the levant). It rise in 11 other centers independently around the world. • plant/ animal domestication May have arisen to feed the ever- increasing human population.

Theories about peopling of America's (when, how, evidence)

• people from Asia populated the new world via the Bering land Bridge connecting Asia the North America b4 15,000 yBP. • maybe by sea route along the pacific coast and maybe even along the Atlantic coastal ice. •

How did agriculture affect human biological change?

• poor-quality diets led to a decline in health. • the shift from hard foods to soft ones resulted in facial bones reducing in size faster then the teeth. -causing orthodontic issues requiring braces. • the decline in health did not affect human reproductive performance.

Homo floresiensis

What are some the advantages becoming an agricultural society?

• supports larger populations • long-term food storage • surplus food allows for occupation specialties -> creates hierarchy to organism and control.

People of the Pacific (when and how)

• the first humans reach Australia, Iansmina, and new guinea by 50,000 YBP evidence (at lake Mungo) Australia • remainder of the Pacific Islands weren't populated until 3500-600 yBP • Australian peoples remained hunter gatherers until the time of colonization.

Homo naledi

• was found in 2013 South Africa by lee Berger's team in the rising star cave system • fossil dates about 250,000 yBP are very primitive in many ways but modern in others. • this discovery reflects the complexity of our evolutionary history.

archaic humans

•(350,000 - 130,000 yBP) , •the earliest humans emerged 350,000 yBP in Africa • they evolved in modern humans in Africa at least as early as 200,000 yBP • "broken hill man" - Zambia

Skeletal traits of modern humans

•A round and tall vertical forehead and small brow ridges. • small face and teeth, well defined chin. • More gracile post-cranial skeleton.

The rise in allergies, and asthma,

•Allergic reactions to food and the modern environment are becoming more common • causes induced genetics, diet, overuse of antibiotics and environmental pollutant

What human evolutionary trends do we see in the fossil within the transition to agriculture?

•Consumption of various grains brought about both nutritional deficiencies and growth disruptions • because of high carbohydrate content corn and other grains promoted tooth decay. • population crowding in close proximity to herd animals lead to appearance of new infectious diseases.

Monte Verde

Assimilation model for modern human variation

•Fully modern humans arose in Africa and then peopled the world. • met up with archaic Homo sapiens such had Neanderthals and denisovan (they were descendants of homo Ere population is Asia) • who contributed to the gene pool.

What are the most important forces shaping human biology today?

•Global warming is altering the environment. Left unchecked can cause threaten food production and continue to negatively affect health. • population increase -nursing resources and reducing well-being. • tech is creating new opportunities for us but new threats

What are the biological consequences on global climate change, population increase and tech?

•Global warming is threatening further food supplies for the growing world pop worsening poorer new regions • increase places stress on resources including food supplies. • lowering earths biodiversity • many common tech changes promotes obesity/ poor healthy

What other developments took place in H. Sapiens evolution?

•More advanced tools, diet diversification, symbolism appeared first in Africa and later in Europe and Asia. • Neanderthals were likely capable of articulate speech

How may new technologies affect human evolution?

•Our immune system will be weaker • There will be a hierarchy of genetically modified people • we're going to get weaker

Neandertal physical characteristics and behaviors

•Round Eye orbits wide space between Eye orbit wide nasal aperture and protruding made facial region. • evidence of housing structure,?large game hunting, fishing use of Rome materials besides stone, skilled tool production buried loved ones, symbolic behavior.

What are the trends in global climate change

•Shifting patterns of precipitation and dryness put agriculture and food systems at risk. •rising sea levels due to melting glaciers will is all.

How has variation in fossil H. Sapiens been interpreted

•The out-of-Africa model argues that modern h.sapiens migrated from Africa to Asia and Europe, replacing native late archaic h. Sapiens, including Neanderthals. • physical characteristics and dna in fossils Neanderthals were assimilated through admixture with early modern h. Sapiens and did not go extinct.
