Jared Diamond, a well-traveled American professor of physiology and, most notably, the world-renowned author of the book Guns, Germs, and Steel: The Fates of Human Societies (1999), famously determined the answer to this question by concluding that the peoples of Eurasia (which included North Africa), not those of Africa south of the Sahara Desert or Australia-New Guinea, were destined, as early as the first days of human life on Planet Earth, to conquer and colonize not just the Americas, but most of the rest of the known world.(Diamond’s capstone work, with the 16th-century illustration of Spanish conquistador Francisco Pizarro capturing the Inca Emperor Atahuallpa in A.D. 1532 as its cover.)He attributes this conclusion to a number of factors:The successes and failures, respectively, of plant and animal domestication in Eurasia and the Americas. The horse in particular (which had previously existed on American soil before the days of European exploration and colonization, until going extinct)—history’s longest-lasting war beast with which the European (especially Spanish) conquistadores managed to overcome the vast hordes of Native Americans—marked a central example of how environment tipped the scales decisively in the Europeans’ favor rather than the American Indians’. (The latter, of course, did ultimately adopt the horse from the Eurasians and then used it as a weapon of resistance against Western expansionism—the Lakota and Cheyenne tribes, for example, succeeded brilliantly against the U.S. Army’s 7th Cavalry battalion under George A. Custer at Little Bighorn, in 1876 (which Diamond himself cites)—though by then it was already too late.)The lack of significant natural and ecological barriers present along Eurasia’s east-west axis, as opposed to the Americas’ north-south axis (e.g., the Andes Mountains, Mexico’s southern desert, and the Isthmus of Panama).Eurasian peoples’ ability to build up an immunity to the vicious diseases (most distinct among them, smallpox) that either wiped out or brought to the verge of total extermination the Aztecs, Incas, and other Native American peoples, a direct result of the frequency and easy accessibility of these diseases made possible by the previously mentioned lack of geographical obstacles within Eurasia.Lastly, and most importantly, Eurasia’s predominantly hospitable geography and climate—drastically incomparable to that of the Americas, much less that of sub-Saharan Africa and Australia—enabled its capacity for supporting food production on a massive scale, thus ensuring greater population densities and, in effect, superior human and societal development in that part of the globe in terms of creating better—i.e. modern—standards of living. (“Thus, food production, and competition and diffusion between societies, led as ultimate causes, via chains of causation that differed in detail but that all involved large dense populations and sedentary living, to the proximate agents of conquest: germs, writing, technology [i.e. guns], and centralized political organization.” (Diamond, p. 292))(The readers of this post who are unfamiliar with Guns, Germs, and Steel should bear in mind that the factors listed above constitute only some of the important factors mentioned in Diamond’s book, and that I have briefly summarized each one of them so to give those readers an introductory taste of this very important and interesting work on the story of humankind’s disparate levels of sophistication reached in the various parts of the world. I strongly encourage everyone to read this book.)All of these factors proved most advantageous for the western Europeans and most detrimental for their American “inferiors” (a word commonly used among white European societies in reference to those more technologically primitive groups of foreigners that they conquered) when, in A.D. 1492, the hemispheres of the Old World and the New finally, and violently, collided. Even the most powerful states that existed in the Americas when Columbus first crossed the ocean blue—the Aztec and Inca Empires—were dealt a poor hand as a result of the natural barriers that surrounded them as well as their own lacking of the means to create the sorts of technologies—namely those of military value, from large, ocean-going ships to steel and gunpowder-fed weapons—that, in Eurasia, helped forge colossal empires in places like classical antiquity-era Greece and Rome, seventh-century Arabia, and thirteenth-century Mongolia. Hence, for the great empires in the New World, such an absence of opportunity for achieving a “superpower” status equal to their Old World contemporaries made impossible their ability to promote trade, exploration, and territorial expansion far beyond their limited spheres of influence in the same ways that led their Spanish, Portuguese, French, English, Dutch, and Russian counterparts triumphantly to “God, gold, and glory.”

Thanks for the A2A.Jim Davis's answer to How do I find the differences between musical genres?Jim Davis's answer to Which music is the best?…and so my answer doesn’t get flagged for brevity:(alphabetically by genre/sub-genre; and no, not “every” genre is included. That would be physically impossible. This is closer to about 10% of all genres/sub-genres. You’re welcome.)Blues:Blues Rock; Similar to Electric Blues, but sometimes acoustic.

Country for the sake of true mountain/southern expression. Hard workin' white trash sadness and hard times with an occasionally poppy feel later in the genre.

Just sort of, “Life is tough and I’m gonna bitch about it” music - but good. -Anberlin, Good Charlotte, Motionless in White, My Chemical Romance, SkilletFusion Metal: including…Folk Metal: including…Celtic Metal; reminiscent of ancient Celtic/Irish battle music. Heavy and grinding, but with an air of ambient atmosphere and possibly pan flutes. Yes definitely pan flutes.

Swashbuckling, rum-guzzling, peg-legged, patch-eyed, hook-armed, parrot-perched ne’er-do-wells prowling the waters in wooden ships carrying gold, gems and ghosts of the sea. At least that’s what they sing about. I think in real life they’re just normal people who drive cars and pay taxes like the rest of us. - Alestorm, Blaxon Stone, Cat O’ Nine Tails, Iron Seawolf, Red Rum, Silverbones, SwashbuckleViking Metal; metal having to do with Vikings (mostly lyrically) and their respective culture.

Not as esoteric as Avant-Garde Metal and more artsy than Funk Metal. Elements of Jazz like improvisation and off-kilter chord structures prevail. -Conflux, Gru, Sithu Aye, Shining, Naked CityNeoclassical Metal; these guys would be composing for their respective local monarchs had they lived 200 years ago. This is metal with classical tendencies, but not necessarily classical instrumentation. Mostly guitar virtuosi hang out here. Their bands are typically comprised of musical over-achievers who don’t quite have what it takes to be fully progressive. -Yngwie Malmsteen, Vinnie Moore, Timmo Tolkki, Joshua Perahia, Marty FriedmanRap Metal; Pretty self-explanatory. Combines rap and metal.- Linkin Park, P.O.D., Kid Rock, Rage Against The Machine, Papa Roach, Crazy Town, Limp BizkitSymphonic Metal; - again, pretty self-explanatory.

More about sex and drugs in the deviant and slimy way. Not really about partying, but about the actual sex and drugs. More leather and fringe than hairspray and makeup. Though you will find some hairspray. And makeup. -Billy Idol, Guns ’n’ Roses, Skid Row, Mötley Crüe, L.A. Guns, ExtremeGroove Metal; Metal with slightly more funk than pure Metal, slightly more balls than Jazz Metal and slightly more balls than pure Funk Metal. Imagine Funk Metal more laid back and less aggressive. Like….if Motown made Metal.

Can become over-commercialized due to its attainability by the masses.- Rob Zombie, Front Line Assembly, God Lives Underwater, Skinny Puppy, NIN, Filter, The Union UndergroundMetalcore; growling, screaming and yelling. Angry people reside here; somewhere between extreme metal and hardcore punk. Hey wait.....Metalpunk? no....Extrard? no.....Punkstreme? no. Metalcore! There. That works.- SOiL, Drowning Pool, Biohazard, The Agonist, Trivium, HelmetNu Metal; guys who use digital production techniques and a more refined sound. Good hardcore stuff, but not raw and dirty. Often have numbers or present tense verbs/gerunds in their names.- 10 Years, 3 Days Grace, 30 Seconds To Mars, Breaking Benjamin, Dropping Daylight, Shinedown, Sevendust, Finger Eleven, KoЯnPower Metal; metal that combines the powerful elements of classic metal, speed metal and a bit of symphonic metal for added drama.

Not always happy, but driven and motivational. -Alestorm, Powerwolf, Metal Church, Iced Earth, Kamelot, HelloweenProgressive Metal; including…Classical Prog; Heavy, yet classical virtuosity runs rampant. Complex orchestrations and thematic derivatives abound. Their album covers are usually pretty Dungeons & Dragons-esque.- Adagio, Blind Guardian, Symphony X, Triumph, The Devin Townsend ProjectDjent; pretty much onomatopoeiaic. Those crunchy guitar sounds that are mimicked by Metalheads using their voices to project “DJENT DJENT DJENT DJENT….” as they mouth along with the kickass guitar riffs. - Animals As Leaders, Meshuggah, Mnemic, Periphery, Sikth, TesseracTMathcore; the guys who are more into technique than groove. Music that exhibits what a theoretical physicist’s chalkboard might sound like if transferred to aural perception. - Benea Reach, Botch, Daughters, Ion Dissonance, Psyopus, Spiral ArchitectMelodic Prog; the guys who are more about melody and tonality than about technical virtuosity. Don’t get me wrong, they’re still damn good, but they produce more memorable and catchy tunes than some other Progressive groups. - Crimson Glory, A Perfect Circle, Tool, Queensrÿche, Rhapsody of Fire, Shadow GalleryOmni Prog; the guys who can do it all. Classical, Rock, Jazz, Funk, Groove, Technique, Passion, Virtuosity, Acoustic, Electric, Slow, Fast, Flamenco, Baroque, etc. Pretty much the embodiment of “Musicians’ Bands”. - Dream Theater, Fates Warning, King’s X, Pain of Salvation, Liquid Tension Experiment, PlatypusPower Prog; virtuosity tempered with sheer power. Hard-driving beats and riffs with high-volume, in-your-face ass-kicking. - Adrenaline Mob, Frameshift, Nevermore, Orden Ogan, Ne Obliviscaris, Seventh WonderTechnical Death Metal; similar to the Mathcore guys but heavier.

Makeup and crazy hair and facial prosthetics abound. - Cherry Vanilla, Flash Bastard, The Hot Dogs, New York Dolls, Shady Lady, Sick Six CrushHardcore; faster, more aggressive Punk.

Music is raw, unproduced, natural; yet maintains an honesty that’s rare in a lot of musical styles. - Last Resort, Peter and the Test Tube Babies, Public Enemy, Street Dogs, SuperYob, Toy DollsPop Punk; music by and for the spoiled, rich-kid wannabes that had started to become “punkers”. Punk in the mainstream. The use of Punk stylings and techniques for the sake of selling albums and making money and becoming famous and rich. - American Hi-Fi, The Ataris, Green Day, OffspringPost-Punk; the evolution of Punk into a more personally stylistic and individually nuanced style. More experiementation and removal from the classic Punk traditions created a sort of Avant-Garde Punk movement which culminated in Post-Punk. - 23 Skidoo, Au Pairs, Bauhaus, Big Black, The Chills, The Cult, The StranglersProto-Punk; the ones who started it all. The original punks. The artists who originally went against the grain of the conventional Rock or Pop of their day to create what would become the Punk movement. - Iggy & The Stooges, MC5, NEU!, The Patti Smith Group, The Sonics, TelevisionPunk Rock; those groups that don’t really fit into any subgenre of Punk and just encapsulate what the common culture knows as “Punk”. - The Clash, The Jam, The Ramones, Sex Pistols, Sprung MonkeySpeed Metal; exactly that. Speed. Even the band names are so fast they only use one word.- Helloween, Overkill, Impellitteri, Cranium, Atomkraft, Annihilator, Sodom, Kreator, GravediggerThrash Metal; the guys you likely know best.

Not as counter-culture as EDM, but slightly heavier than Bubble Gum Pop; which I didn't list as a category.- Bananarama, Billy Ocean, Katy Perry, Lady Gaga, Debbie Gibson, EMF, Will to Power, TiffanyDisco; formed from funk, psychedelic and soul; this style rebelled against the rock music of the day in a more visceral, primal way. All about body movement, dancing and the human spectacle, it stole colorful clothing and drugs from the Hippies, up-beat driven rhythms from the Beatniks and combined them in a sexy, seductive libido-based production praising dance and expressive human life. It is currently "dead".- ABBA, The Bee Gees, The Village People, KC & The Sunshine Band, Gloria Gaynor, Lipps Inc.Doo Wop; yet another mainstream derivative of African-American music, doo wop uses more nonsensical phrases and sounds to emphasize harmony and melody over lyrical substance. These names also are often "The" something.- The Dominoes, The Platters, The Tune-Weavers, The Casinos, The Dreamlovers, The Passions, The Penguins, The Rivieras, The Esquires, Bob & Earl.Indie Pop; somewhat contradictory, the emphasis on self-reliance and the whole DIY perspective is exploited to assure popularity and mainstream success.

Actually Bluegrass is a subgenre of Country music. However I can see where the two get confused. Some people might think Bluegrass is Country for Hillbillies and Hipsters rather than Cowboys and Rednecks (But that's a bunch of stereotypes), or that any Acoustic Country music is bluegrass, many early country artists (Jimmie Rodgers, Carter Family, Roy Acuff) although having a big in influence on Bluegrass, might be confused for Bluegrass for simply being acoustic.The one main important thing that separates Bluegrass from Country is that Bluegrass is String Band music based.Basically Bluegrass is very heavily based off of old time string bands. The main instruments in Bluegrass are string band instruments, Guitar, Banjo, Mandolin, Fiddle, Upright Bass (along with the Dobro and Harmonica here and there) are what most Bluegrass bands ( both Traditional and Newgrass) very often use.A big difference however from Old Time string band music, is that Bluegrass is basically more “free" musically (basically old time music is very strict on “Tradition" and has less improv) and Bluegrass incorporates elements of other genres of music like early country, blues, and Jazz (and takes instrumental solos inspired by jazz bands). Improv is a big role in Bluegrass and most Bluegrass songs feature solos that are improvised on the spot.A big difference in Bluegrass from many Country music is that Bluegrass has a very big focus with the instrumental parts and often the musicianship of the instrumentalist is a big part of bluegrass. Although many Bluegrass musicians focus on songwriting and many Bluegrass songs are often simple in chord structure, the instrumental parts can still be pretty complex and are important to many songs.I think it would best to compare a classic country song being done by a classic country singer and a bluegrass band. Let's use the Jimmie Rodgers songs “Mule Skinner Blues/ Blue Yodel #8″ being done by Jimmie Rodgers (who is considered to be the godfather of Country music) and a Bill Monroe and His Bluegrass Boys (Basically the original Bluegrass musicians).Here is the Jimmie Rodgers original:Now here is Bill Monroe's version:As you can see the original Jimmie Rodgers version is basically a folksy white guy singing the blues and features simple folk and blues guitar for accompaniment. Meanwhile Bill Monroe's version is much more complex instrumentally and sounds like it's being sung by hillbilly from the mountains (although many early bluegrass musicians disliked the label “hillbilly” and would dress up fancy in order to avoid it).Another Classic Country and Western string band genre that some people might confuse it with and/or for Bluegrass is Western Swing. However after actually listening to a Western Swing song you can see it's different from Bluegrass. Here is a Bob Willis (the king of Western Swing) song:As you can see, along with being more based of the music of the Southwest (Texas, Oklahoma, New Mexico) rather than the Appalachians of Bluegrass. Western Swing is inspired more by the Hot String Bands of the popular Swing music, but being played with Country and Western instruments (however Western Swing bands were using instruments not often used in Bluegrass and also not yet common in Country music like Drums, Electric Steel Guitars (rather than the acoustic Dobro), Electric guitars, and even horns.Today Bluegrass and Country music might seem very different because a lot of music that is called Country music is basically pop music with a twang. However some Country singers might play some Bluegrass music, Chris Stapleton is a notable example as he was in a Bluegrass band (the SteelDrivers) before becoming a very popular Country singer.Today Bluegrass seems to have two main types, Traditional and Newgrass. Traditional Bluegrass is more based off of the classic Bluegrass music. Meanwhile Newgrass is much more eclectic and can be inspired by other genres of music, and can also sometimes use non-traditional bluegrass instruments (such as electric guitars, electric basses, accordions, pianos, ukuleles, etc) or have Bluegrass instruments being played in non traditional ways.Alison Krauss is a well known example of modern Traditional Bluegrass:The band Trampled By Turtles (which is an absolute favorite of mine) is a good example of Newgrass:Anyways I hope this answer helps!
