physics
the science of matter (that which has mass and occupies space) and energy and their interactions.
“ABOUT 13.5 BILLION YEARS AGO, MATTER, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics.”
chemistry
The science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions. “About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then combined into molecules. The story of atoms, molecules and their interactions is called chemistry.”
biology
About 3.8 billion years ago, on a planet called Earth, certain molecules combined to form particularly large and intricate structures called organisms. The story of organisms is called biology. About 70,000 years ago, organisms belonging to the species Homo sapiens started to form even more elaborate structures called cultures. The subsequent development of these human cultures is called history. MD - fossilized microorganisms found in hydrothermal vent precipitates 3.77 million years ago.

Time of cognitive revolution, agricultural revolution, and scientific Revolution
cognititive revolution - 70,000 years ago agricultural revolution - 12,000 years ago scientific revolution - 500 years ago Three important revolutions shaped the course of history: the Cognitive Revolution kick-started history about 70,000 years ago. The Agricultural Revolution sped it up about 12,000 years ago. The Scientific Revolution, which got under way only 500 years ago, may well end history and start something completely different. This book tells the story of how these three revolutions have affected humans and their fellow organisms. MD - cognitive revolution - massive human brain allowed sapiens to be the dominant species in the genus - signal to other sapiens about the world and gossip about social relationships. and + the ability to create fiction. watch out for that lion watch out for conrade you can’t lend him money, and joseph conrade - fiction. - agricultural revolution - grain cultivation (barley) and domestic pigs - scientific revolution Cognitive revolution - sound for 7 agricultural revolution - 12,000 years ago - tin hoe 500 years ago - scientific revolution (around 1519?) Law - like the natural laws Isaac Newton

archaic
- of a much earlier time 2. having the character or characteristics of a much earlier time These archaic humans loved, played, formed close friendships and competed for status and power, but so did chimpanzees, baboons and elephants. There was nothing special about humans. Nobody, least of all humans themselves, had any inkling that their descendants would one day walk on the moon, split the atom, fathom the genetic code and write history books. The most important thing to know about prehistoric humans is that they were insignificant animals with no more impact on their environment than gorillas, fireflies or jellyfish. MD - archaeology strives to understand archaic past by uncovering artifacts. indiana jones holding an artifcact - the golden idol - belonging to the Chachapoyas for Peru (Warriors of the Clouds) a culture of the Andes living in the cloudforest of Peru who were conquered by the Incas who shorlty after were conquered by the Spanish conquest in the 16th century.

what does belonging to the same species.mean?
Animals are said to belong to the same species if they tend to mate with each other, giving birth to fertile offspring. Biologists classify organisms into species. Animals are said to belong to the same species if they tend to mate with each other, giving birth to fertile offspring. Horses and donkeys have a recent common ancestor and share many physical traits. But they show little sexual interest in one another. they will mate if induced to do so - but their offspring, called mules, are sterile. Mutations in donkey DNA can therefore not cross over to horses, or vice versa. The two types of animals are consequently considered two distinct species, moving along separate evolutionary paths.” (loc 116) MD - Horse and Donkey mating and creating a mule which is sterile. show mutations from horse and mutations from donkey not able to cross over, a stop sign in between.

genus
“Species that evolved from a common ancestor are bunched together under the heading ‘genus’ (plural genera). Lions, tigers, leopards and jaguars are different species within the genus Panthera. Biologists label organisms with a two0part Latin name, genus followed by species. Lions, for example, are called Panthera leo, the species leo of the genus Panthera. Presumably, everyone reading this book is a Homo sapiens - the species sapiens (wise) of the genus Homo (man).” MD - cats - family (lions, cheetas, house cats) Panthera - outlines of lions, tigers, leopards, and jaguars followed by species - panthera leo being the lion

family
genera in their turn are grouped into families, such as cats (lions, cheetas, house cats), the dogs (wolves, foxes, jackals) and the lephants (elephants, mammoths, mastodons). All members of a family trace their lineage back to a founding matriarch or patriarch. All cats, for example, from the smallest house kitten to the most ferocious lion, share a common feline ancestor who lived about 25 million years ago.” (loc 123) MD -

ape (hominoid - member of the superfamily Hominoidea: extant members are the gibbons (lesser apes, family Hylobatidae) and the hominids. A hominid is a member of the family Hominidae, the great apes: orangutans, gorillas, chimpanzees, and humans.)
any of various large tailless semi-erect primates of Africa and southeastern Asia (such as the chimpanzee, gorilla, orangutan, or gibbon) “Just 6 million years ago, a single female ape had two daughters. One became the ancestor of all chimpanzees, the other is our own grandmother.” Location 133 MD - ape apple no tail can draw an apple that is tilted (semi-erect) big to

homo
any of a genus (Homo) of hominids that includes modern humans (H. sapiens) and several extinct related species (such as H. erectus and H. habilis)
any living or extinct member of the family Hominidae characterized by superior intelligence, articulate speech, and erect carriage. “Yet the real meaning of the word human is ‘an animal belonging to the genus Homo’, and there used to be many other species of this genus besides Homo sapiens. Moreover, as we shall see in the last chapter of the book, in the not so distant future we might again have to contend with non-sapiens humans. To clarify this point, I will often use the term ‘Sapiens’ to denote members of the species Homo sapiens, while reserving the term ‘human’ to refer to all members of the genus Homo.” MD - human - belonging to the genus homo “any living or extinct member of the family Hominidae characterized by superior intelligence, articulate speech, and erect carriage. apple that is fully erect with Hume’s face”” ““A wise man proportions his belief to the evidence.

homo erectus
the oldest known early humans. they were around for 2 million years whereas homo sapiens were only around for 200,000 years “The more eastern regions of Asia were populated by Homo erectus, ‘Upright Man’, who survived there for close to 2 million years, making it the most durable human species ever. This record is unlikely to be broken even by our own species. It is doubtful whether Homo sapiens will still be around a thousand years from now, so 2 million years is really out of our league.” MD - the oldest known early humans name erectus - this is what separated humans from the semi - erect apes.
We’ve only lived for 10 percent of the time homo erectus lived.
homonidae
a taxonomic family (/hɒˈmɪnɪdiː/), whose members are known as great apes[note 1] or hominids, are a taxonomic family of primates that includes eight extant species in four genera: Pongo, the Bornean, Sumatran and Tapanuli orangutan; Gorilla, the eastern and western gorilla; Pan, the common chimpanzee and the bonobo; and Homo, which includes modern humans and its extinct relatives (e.g., the Neanderthal), and ancestors, such as Homo erectus.[1] homonidae - family great apes as opposed to lesser apes - called great because of their larger bodies and brains. orangutan gorilla, chimpanzee and bonobo, homo,

insular dwarfism
is the process and condition of large animals having a reduced body size when their population’s range is limited to a small environment, primarily islands. “Humans first reached Flores (island in the eastern part of Indonesia) when the sea level was exceptionally low, and the island was easily accessible from the mainland. When the seas rose again, some people were trapped on the island, which was poor in resources. Big people, who need a lot of food, died first. Smaller fellows survived much better. Over the generations, the people of Flores became dwarves. This unique species, known by scientists as Homo floresiensis, reached a maximum height of only 3.5 feet and weighed no more than fifty-five pounds. They were nevertheless able to produce stone tools, and even managed occasionally to hunt down some of the island’s elephants – though, to be fair, the elephants were a dwarf species as well.” insular - island - limited resources (think of survivor island in china which only had rats and snakes

why sapiens are born prematurely
natural selection favored childbirth at an earlier stage of fetal development to accommodate selection for both large brain size and upright locomotion—defining characteristics of the human lineage. “And, indeed, compared to other animals, humans are born prematurely, when many of their vital systems are still under-developed. A colt can trot shortly after birth; a kitten leaves its mother to forage on its own when it is just a few weeks old. Human babies are helpless, dependent for many years on their elders for sustenance, protection and education.” “Early birth was an adaption to expanding brain and narrowing hips” MD - narrow hips and growing brain, big brain can’t make it out of the canal at 18 - 21 monhts, but 9 month smaller underdeveloped human brain can make it out. human fetus would have to undergo a gestation period of 18 to 21 months instead of the usual nine to be born at a neurological and cognitive development stage comparable to that of a chimpanzee newborn. short gestation period narrow hips and big brain
bone marrow
Bone marrow is the spongy tissue inside your bones. It’s home to blood vessels and stem cells that help produce: red and white blood cells. “One of the most common uses of early stone tools was to crack open bones in order to get to the marrow. Some researchers believe this was our original niche. Just as woodpeckers”
banana republic
In political science, the term banana republic describes a politically unstable country with an economy dependent upon the exportation of a limited-resource product, such as bananas or minerals. In 1901, the American author O. Henry coined the term to describe Honduras and neighboring countries under economic exploitation by U.S. corporations, such as the United Fruit Company.
“As lions became deadlier, so gazelles evolved to run faster, hyenas to cooperate better, and rhinoceroses to be more bad tempered. In contrast, humankind ascended to the top so quickly that the ecosystem was not given time to adjust. Moreover, humans themselves failed to adjust. Most top predators of the planet are majesctic creatures. Millions of years of dominion have filled them with self-confidence. Sapiens by contrast is more like a banana republic dictator. Having so recently been one of the underdogs of the savannah, we are full of fears and anxieties over our position, which makes us doubly cruel and dangerous. Many historical calamities, from deadly wars to ecological catastrophes, have resulted from this over-hasty jump.” MD Politically unstable - a banana is likely going to be peeled (it’s unstable) banana - the one export product

advantages of cooking food
The advent of cooking enabled humans to eat more kinds of food, to devote less time to eating, and to make do with smaller teeth and shorter intestines. But the best thing fire did was cook. Foods that humans cannot digest in their natural forms – such as wheat, rice and potatoes – became staples of our diet thanks to cooking. Fire not only changed food’s chemistry, it changed its biology as well. Cooking killed germs and parasites that infested food. Humans also had a far easier time chewing and digesting old favourites such as fruits, nuts, insects and carrion if they were cooked. Whereas chimpanzees spend five hours a day chewing raw food, a single hour suffices for people eating cooked food. The advent of cooking enabled humans to eat more kinds of food, to devote less time to eating, and to make do with smaller teeth and shorter intestines. Some scholars believe there is a direct link between the advent of cooking, the shortening of the human intestinal track, and the growth of the human brain. Since long intestines and large brains are both massive energy consumers, it’s hard to have both. By shortening the intestines and decreasing their energy consumption, cooking inadvertently opened the way to the jumbo brains of Neanderthals and Sapiens. MD cooking - potatoes - are indegestible - increases the food we can eat through the upper intestine with little change. They arrive in the lower intestine largely intact, where they begin to ferment under the influence of intestinal bacteria. The result of this fermentation is the production of gas, which can cause bloating, cramping and flatulence. Although none of these effects are a threat to health, they are uncomfortable and inconvenient. - reduces the chewing and digestion time carrion - a dead gazelle - chimp teeth and intestines versus human teeth and intestines - it allows the fibrous fruits, stems, and leaves to be digested (i.e., fermented by gut bacteria) for a longer period of time.

supple
a. moving and bending with ease b. readily adaptable or responsive to new situations “The most common answer is that our language is amazingly supple. We can connect a limited number of sounds and signs to produce an infinite number of sentences, each with a distinct meaning.” Webster - ELASTIC, RESILIENT, SPRINGY, FLEXIBLE, SUPPLE mean able to endure strain without being permanently injured. SUPPLE applies to something that can be readily bent, twisted, or folded without any sign of injury. MD - a sup pole (supper pole) that moves and bends with ease the sup pole moving and bending with eas through different restaurant dores. and is readily adaptable and responsive to new situations, it can make supper in any type of restaurant. pic - sup pole in german restaurant with pretzel, in japanese restaurant with sushi.
theory on why language evolved (not about the world around us, about….
language evolved as a way of conveying information about humans. “A second theory agrees that our unique language evolved as a means of sharing information about the world. But the most important information that needed to be conveyed was about humans, not about lions and bison. Our language evolved as a way of gossiping. According to this theory Homo sapiens is primarily a social animal. Social cooperation is our key for survival and reproduction. It is not enough for individual men and women to know the whereabouts of lions and bison. It’s much more important for them to know who in their band hates whom, who is sleeping with whom, who is honest, and who is a cheat. MD - Russel - tribal council in survivor. ability to get along, manipulate, and strategize with people is most important. Old school new school.
maligned
spoken unfavorably about Neanderthals and archaic Homo sapiens probably also had a hard time talking behind each other’s backs, a much maligned ability which is in fact essential for cooperation in large numbers. MD - maligned - the body will speak unfavorably about a
Max size of a group bonded by gossip
150 “Under natural conditions, a typical chimpanzee troop consists of about twenty to fifty individuals…..Sociological research has shown that the maximum ‘natural’ size of a group bonded by gossip is about 150 individuals. Most people can neither intimately know, nor gossip effectively about, more than 150 human beings.”
incarnated
embody or represent (a deity or spirit) in human form: • put (an idea or other abstract concept) into concrete form: a desire to make things which will incarnate their personality. • (of a person) be the living embodiment of (a quality): the man who incarnates the suffering which has affected every single Mozambican. “Any large-scale human cooperation - whether a modern state, a medieval church, an ancient city or an archaic tribe - is rooted in common myths that exist only in people’s collective imagination. Churches are rooted in common religious myths. Two Catholics who have never met can nevertheless go together on crusade or pool funds to build a hospital because they both believe that God was incarnated in human flesh and allowed Himself to be crucified to redeem our sins.” (28) MD - carne asada - GOD incarnates himself as the living embodiment of man grilling a carne asada which is deliciousness (an idea or abstract concept) incarnate. and the man that God is the emobidment of manliness (quality)
Hominoidea: extant members are the gibbons (lesser apes, family Hylobatidae) and the hominids. A hominid is a member of the family Hominidae
